Operation  
Overview  
This section outlines the operations of the mechanism and control  
units of the scanner.  
OVERVIEW  
Operation of the mechanism unit  
The mechanism unit consists of two optical units (front and back  
sides), a hopper and ADF, upper and lower transport units, a motor  
drive system, and a stacker. Each optical unit consists of a CCD  
image sensor, a lens, and mirrors. The hopper and ADF feeds  
stacked documents and the upper and lower transport units transport  
the documents. The motor drive system drives these units. The  
stacker stores documents.  
When the power is turned on, the lamps are lit and the scanner  
waits until the light intensities of the lamps become stable. Once the  
light intensities have become stable, the scanner is ready for a  
command from the host machine.  
A document is picked from the hopper and then ADF feeds a  
document one by one. The document width is checked and  
document top is detected.  
The documents are counted, fed, and stacked on the stacker.  
The lamps illuminate the document, and a lens focuses the images  
on CCD for photoelectric conversion processing.

Main control unit  
OVERVIEW  
This scanner is controlled by a 80C186 MPU. This scanner consists  
of a ROM as a program area, internal registers, an external RAM as a  
work area, gate arrays for the MPU peripheral and video circuits,  
dither processing and γ conversion RAMs, and error diffusion.  
Interface control  
SCSI-2 interface  
SCSI (small computer system interface) circuit consists of SPC  
(MB86601A), VCEP (OTI95C71/20) and a glue ASIC. The scanned  
image data are transferred to interface circuit as video interface. The  
interface circuit converts internal video interface to SCSI interface via  
compression, if required. SCSI interface transferes data 1.5MB/s in  
Asynchronous transfer, 4.0MB/s in Synchronous transfer following to  
SCSI-2 standard. The VCEP compresses the binary image data in  
MH, MR, MMR algorithm defined by CCITT G3, G4. See Chapter  
3 for details of SCSI interface.  
Resolution  
The basic resolution of this scanner is 200dpi. The resolution can be  
changed to 240, 300, or 400dpi from the host computer or the  
operator panel.  
The resolution in the subscanning direction is achieved by changing  
the document transport speed.  
When the image processing circuit II (IPC II) option is installed, the  
linear density is changed by setting the parameter to its internal circuit.  
Video amplifier and driver section  
This section consists of a CCD drive circuit, a video amplifier circuit,  
a white-black level correction circuit, sensors, and also control circuits  
for the stepping motor, heater, and lamps.

Connection  
SCSI devices are daisy-chaned together using a common 50-  
conductor ‘A’ cable and, optionally, a 68-conductor ‘B’ cable. Both  
ends of each cable are terminated. All signals are common between  
all SCSI devices on the ‘A’ cable. In systems that employ the wide  
SCSI option, wide SCSI devices additionally connect to the ‘B’ cable.  
Various width SCSI devices may be mixed. This scanner supports ‘A’  
cable.  
Note: Use of ‘B’ cable is not recommended because of ANSI draft  
proposal indicates this definition is removed in a future  
version of the SCSI.

SCSI Bus Signals (See ANSI SCSI-2 4.6)  
Table 3.3 SCSI Bus Signals  
Signal  
Description  
BSY(BUSY)  
An "OR tied" signal that indicates that the bus is  
being used.  
SEL(SELECT)  
C/D  
An "OR tied" signal used by an initiator to select  
a target or by a target to reselect an initiator.  
A signal driven by a target that controls the  
(CONTROL/DATA) direction of data movement on the DATA BUS  
with respect to an initiator. True indicates input  
to the initiator. This signal is also used to  
distiguish between SELECTION and  
RESELECTION phase.  
MSG(MESSAGE)  
REQ(REQUEST)  
A signal driven by a target during the MESSAGE  
phase.  
A signal driven by a target on the A cable to  
indicate a request for an ACK information  
transfer handshake.  
ACK  
A signal driven by an initiator on the A cable to  
(ACKNOWLEDGE) indicate an acknowledgement for a REQ  
information transfer handshake.  
ATN(ATTENTION) A signal driven by an initiator to indicate the  
ATTENTION condition.  
RST(RESET)  
An "OR tied" signal that indicates the RESET  
condition.  
DB(7-0,P)  
(DATA BUS)  
Eight data bit signals, plus a parity bit signal that  
from a DATA BUS. DB(7) is most significant bit  
and has the highest priority during the  
ATTENTION phase. Bit number, significance  
and priority decrese downward to DB(0). A data  
bit is defined as one when the signal value is true  
and is defined as zero when the signal value is  
false. Data parity DB(P) shall be odd. Parity is  
undefined during the ARBITRATION phase.

Signal Values  
Signals may assure true or false values. These are two methods of  
driving these signals. In both cases, the signal shall be actively driven  
true, or asserted. In the case of OR tied drivers, the driver does not  
drive the signal to the false state, rather the bias circuitry of the bus  
terminators pulls the signal false whenever it is released by the drivers  
at every SCSI device. If any driver is asserted, then the signal is true.  
In the case of non OR tied drivers, the signal may be actively driven  
false. In this standard, whenever the term negated is used, it means  
that the signal may be actively driven false, or may be simply released  
(in which case the bias circuitry pulls it false), at the option of the  
implementor.  
INTERFACE  
Signal Source  
Table 3.4. indicates which type of SCSI device is allowed to source  
each signal. No attempt is made to show if the source is driving  
asserted driving negated, or is passive. All SCSI device drivers that are  
not active sources be in the passive state. The RST signal may be  
asserted by any SCSI device at any time.

SCSI Bus Timing  
Unless otherwise indicated, the delay time measurements for each  
SCSI device, shown in Table 3.5., shall be calculated from signal  
conditions existing at that SCSI device’s own SCSI bus connection.  
Thus, these measurements (except cable skew delay) can be made  
without considering delays in the cable. The timing characteristics of  
each signal are described in the following paragraphs.

Arbitration Delay  
The minimum time an SCSI device shall wait from asserting BSY for  
arbitration until the DATA BUS can be examined to see if  
arbitration has been won. There is no maximum time.  
Assertion period  
The minimum time that a target shall assert REQ (or REQB) while  
using synchronous data transfers. Also, the minimum time that an  
initiator shall assert ACK (or ACKB) while using synchronous data  
transfers. REQB and ACKB timings only apply to optional wide data  
transfers.  
Bus Clear Delay  
The maximum time for an SCSI device to stop driving all bus signals  
after:  
• The BUS FREE phase is detected.  
• SEL is received from another SCSI device during the  
ARBITRATION phase.  
• The transition of RST to true.  
For the first condition above, the maximum time for an SCSI device  
to clear the bus is 1200 nanoseconds from BSY and SEL first  
becoming both false. If an SCSI device requires more than a bus  
settle delay to detect BUS FREE phase, it shall clear the bus within a  
bus clear delay minus the excess time.  
Bus Free Delay  
The minimum time that an SCSI device shall wait from its detection  
of the BUS FREE phase until its assertion of BSY when going to the  
ARBITRATION phase.  
Bus Set Delay  
The maximum time for an SCSI device to assert BSY and its SCSI  
ID bit the DATA BUS after it detects BUS FREE phase for the  
purpose of entering the ARBITRATION phase.

Bus Settle Delay  
The minimum time for wait for the bus to settle after changing  
certain control signals as called out in the protocol definitions.  
Cable Skew Delay  
INTERFACE  
The maximum difference in propergation time allowed between any  
two SCSI bus signals measured between any two SCSI devices.  
Data Release Delay  
The maximum time for an initiator to release the DATA BUS signals  
following the transition of the I/O signals from false to true.  
Deskew Delay  
The minimum time required for deskew of certain signals.  
Disconnection Delay  
The minimum time that a target shall wait after releasing BSY before  
participating in an ARBITRATION phase when honoring a  
DISCONNECT message from the initiator.  
Hold Time  
The minimum time added between the assertion of REQ(or REQB)  
or ACK(or ACKB) and the changing of the data lines to provide  
hold time in the initiator or target while using synchronous data  
transfers. REQB and ACKB timings only apply to optional wide data  
transfers.  
Negation Period  
The minimum time that a target shall negate REQ (or REQB) while  
using synchronous data transfers. Also, the minimum time that an  
initiator shall negate ACK (or ACKB) while using synchronous data  
transfers. REQB and ACKB timings only apply to optional wide data  
transfers.

Power-On to Selection Time  
The recommended maximum time from power application until an  
SCSI target is able to respond with appropriate status and sense data  
to the TEST UNIT READY, INQUIRY, and REQUEST SENSE  
commands.  
Reset to Selection Time  
The recommended maximum time after a hard RESET condition  
until an SCSI target is able to respond with appropriate status and  
sense data to the TEST UNIT READY, INQUIRY, and REQUEST  
SENSE commands.  
Reset Hold Time  
The minimum time for which RST is asserted. There is no  
maximum time.  
Selection Abort Time  
The maximum time that a target (or initiator) shall take from its  
most recent detection of being selected (or reselected) until asserting  
a BSY response. This time-out is required to ensure that a target (or  
initiator) does not assert BSY after a SELECTION (or  
RESELECTION) phase has been aborted. This is not the selection  
time-out period; see ANSI SCSI-2 6.1.3.1. and ANSI SCSI-2  
6.1.4.2. for a complete description.  
Selection Time-out Delay  
The minimum time that a SCSI device should wait for a BSY  
response during the SELECTION or RESELECTION phase before  
starting the time-out procedure. Note that this is only a  
recommended time period.

Transfer Period  
The Transfer Period specifies the minimum time allowed between  
the leading edges of successive REQ pulses and of successive ACK  
pulses while using synchronous data transfers. (See ANSI SCSI-2  
6.1.5.2 and ANSI SCSI-2 6.6.21.)  
INTERFACE  
The SCSI architecture includes eight distinct phases:  
a) BUS FREE phase  
SCSI Bus Phases  
b) ARBITRATION phase  
c) SELECTION phase  
d) RESELECTION phase  
e) COMMAND phase  
f) DATA phase  
These phases are collectively termed  
the information transfer phase.  
g) STATUS phase  
h) MESSAGE phase  
The SCSI bus can never be in more than one phase at any given  
time. In the following descriptions signals that are not mentioned  
shall not be asserted.  
BUS FREE Phase (See ANSI SCSI-2 6.1.1 for details)  
The BUS FREE phase indicates that there is no current I/O process  
and that the SCSI bus is available for a connection.  
SCSI devices shall detect the BUS FREE phase after the SEL and  
BSY signals are both false for at least a bus settle delay.  
SCSI devices shall release all SCSI bus signals within a bus clear delay  
after the BSY and SEL signals become continuously false for a bus  
settle delay. If an SCSI device requires more than a bus settle delay to  
detect the BUS FREE phase then it shall release all SCSI bus signals  
within a bus clear delay minus the excess time to detect the BUS  
FREE phase. The total time to clear the SCSI bus shall not exceed a  
bus settle delay plus a bus clear delay.

If an initiator detects the release of the BSY signal by the target at  
any other time, the target is indicating an error condition to the  
initiator. The target may perform this transition to the BUS FREE  
phase independent of the state of the ATN signal. The initiator shall  
manage this condition as an unsuccessful I/O process termination.  
The target terminates the I/O process by clearing all pending data  
and status information for the affected nexus. The target may  
optionally prepare sense data that may be retrieved by a REQUEST  
SENSE command.  
ARBITRATION Phase  
The ARBITRATION phase allows one SCSI device to gain control  
of the SCSI so that it can initiate or resume an I/O process.  
The procedure for an SCSI device to obtain control of the SCSI bus  
is as follows:  
a) The SCSI device shall first wait for the BUS FREE phase to  
occur. The BUS FREE phase detected whenever both the BSY  
and SEL signals are simultaneously and continuously false for a  
minimum of a bus settle delay.  
b) The SCSI device shall wait a minimum of a bus free after  
detection of the BUS FREE phase (i.e. after the BSY and SEL  
signals are both false for a bus settle delay) before driving any  
signal  
c) 3)Following the bus free delay in Step(b), the SCSI device may  
arbitrate for the SCSI bus by asserting both the BSY signal and its  
own SCSI ID, however the SCSI device shall not arbitrate (i.e.  
assert the BSY signal and its SCSI ID) if more than a bus settle  
delay has passed since the BUS FREE phase was last observed.

d) After waiting at least an arbitration delay (measured from its  
assertion of the BSY signal) the SCSI device shall examine the  
DATA BUS. If a higher priority SCSI ID bit is true on the  
DATA BUS (DB(7) is the highest), then the SCSI devices has  
lost the arbitration and the SCSI device may release its signals  
and return to Step(a). If no higher priority SCSI ID bit is true on  
the DATA BUS, then the SCSI device has won the arbitration  
and it shall assert the SEL signal. Any SCSI device other than the  
winner has lost the arbitration and shall release the BSY signal  
and its SCSI ID bit within a bus clear delay after the SEL signal  
becomes true. An SCSI device that loses arbitration may return to  
Step(a).  
INTERFACE  
e) The SCSI device that wins arbitration shall wait at least a bus  
clear delay plus a bus settle delay after asserting the SEL signal  
before changing any signals.  
SELECTION Phase  
The SELECTION phase allows an initiator to select a target for the  
purpose of initiating some target function (e.g., READ or WRITE  
command). During the SELECTION phase the I/O signal is  
negated so that this phase can be distinguished from the  
RESELECTION phase.  
The SCSI device that won the arbitration has both the BSY and SEL  
signals asserted and has delayed at least a bus clear delay plus a bus  
settle delay before ending the ARBITRATION phase. The SCSI  
device that won the arbitration becomes an initator by not asserting  
the I/O signal.  
The initiator shall set the DATA BUS to a value which is the OR of  
its SCSI ID bit and the target’s SCSI ID bit and it shall assert the  
ATN signal (indicating that a MESSAGE OUT phase is to follow  
the SELECTION phase). The initiator shall the wait at least two  
deskew delays and release the BSY signal. The initiator shall then  
wait at least a bus settle delay before looking for a response from the  
target.  
The target shall not respond to selection if bad parity is detected.  
Also, if more than two SCSI ID bits are on the DATA BUS, the  
target shall not respond to selection.

No less than two deskew delays after the initiator detects the BSY  
signal is true, it shall release the SEL signal and may change the  
DATA BUS. The target shall wait unitl the SEL signal is false before  
asserting the REQ signal to enter an information transfer phase. (See  
ANSI SCSI-2 6.1.3.1 SELECTION Time-out Procedure)  
RESELECTION Phase  
RESELCTION is an optional phase that allows a target to reconnect  
to an initiator for the purpose of continuing some operation that was  
previously started by the initiator but was suspended by the  
target(i.e., the target disconnected by allowing a BUS FREE phase to  
occur before the operation was completed).  
RESELECTION  
Upon completing the ARBITRATION phase, the winning SCSI  
device has both the BSY and SEL signals asserted and has delayed at  
least a bus clear delay plus a bus settle delay. The winning SCSI  
device becomes a target by asserting the I/O signal. The winning  
SCSI device shall also set the DATA BUS to a value that is the  
logical OR of its SCSI ID bit and the initiator’s SCSI ID bit. The  
target shall wait at least two deskew delays and release the BSY signal.  
The target shall wait at least a bus settledelay before looking for a  
response from the initiator.  
The initiator shall determine that it is reselected when the SEL and  
I/O signals and its SCSI ID bit are true and the BSY signal is false  
for at least a bus settle delay. The reselected initiator may examine  
the DATA BUS in order to determine the SCSI ID of the reselecting  
target. The reselected initiator shall then assert the BSY signal within  
a selection abort time of its most recent detection of being reselected;  
this is required for correct operation of the time-out procedure. The  
initiator shall not respond to a RESELECTION phase if bad parity  
is detected.  
Also, the initiator shall not respond to a RESELECTION phase if  
other than two SCSI ID bits are on the DATA BUS.

After the target detects the BSY signal is true, it shall also assert the  
BSY signal and wait at least two deskew delays and then release the  
SEL signal. The target may then change the I/O signal and the  
DATA BUS. After the reselected initiator detects the SEL signal is  
false, it shall release the BSY signal. The target shall continue  
asserting the BSY signal until it relinquished the SCSI bus. (See  
ANSI SCSI-2 6.1.4.2. RESELECTION Time-out Procedure)  
INTERFACE  
Information Transfer Phases  
NOTE: The COMMAND, DATA, STATUS, and MESSAGE  
phases are all grouped together as the information transfer phases  
because they are all used to transfer data or control information via  
the DATA BUS. The actual content of the information is beyond  
the scope of this section.  
The C/D, I/O, and MSG signals are used to distinguish between the  
different information transfer phases(see Table 3.6). The target  
drives these three signals and therefore controls all changes from one  
phase to another. The initiator can request a MESSAGE OUT phase  
by asserting the ATN signal, while the target can cause the BUS  
FREE phase by releasing the MSG, C/D, I/O, and BSY signals.  
The information transfer phases use one or more REQ/ACK  
handshakes to control the information transfer. Each REQ/ACK  
handshake allows the transfer of one byte of information. During the  
information transfer phases the BSY signal shall remain true and the  
SEL signal shall remain false. Additionally, during the inforamtion  
transfer phases, the target shall continuously envelope the REQ/ACK  
handshake(s) with the C/D, I/O, and MSG signals in such a manner  
that these control signals are valid for a bus settle delay before the  
assertion of the REQ signal of the first handshake and remain valid  
until after the negation of the ACK signal at the end of the  
handshake of the last transfer of the phase.

Asynchronous Information Transfer  
The target shall control the direction of information transfer by  
means of the I/O signal. When the I/O signal is true, information  
shall be transferred from the target to the initiator. When the I/O  
signal is false, information shall be transferred from the initiator to  
the target. If the I/O signal is true (transfer to the initiator), the  
target shall first drive the DB(7-0,P) signals to their desired values,  
delay at least one deskew delay plus a cable skew delay, then assert  
the REQ signal. The DB(7-0,P) signals shall remain valid until the  
ACK signal is true at the target. The initiator shall read the DB(7-  
0,P) signals after the REQ signal is true, then indicate its acceptance  
of the data by asserting the ACK signal. When the ACK signal  
becomes true at the target, the target may change or release the  
DB(7-0,P) signals and shall negate the REQ signal. After the REQ  
signal is false the initiator shall then negate the ACK signal. After the  
ACK signal is false the target may continue the transfer by dividing  
the DB(7-0,P) signals and asserting the REQ signal, as described  
above.

If the I/O signal is false (transfer to the target) the target shall request  
information by asserting the REQ signal. The initiator shall drive the  
DB(7-0,P) signals to their desired values, delay at least one deskew  
delay plus a cable skew delay and assert the ACK signal. The initiator  
shall continue to drive the DB(7-0,P) signals until the REQ signal is  
false. When the ACK becomes true at the initiator, the initiator may  
change or release the DB(7-0,P) signals and shall negate the ACK  
signal. After the ACK signal is false the target may continue the  
transfer by asserting the REQ signal, as described above.  
INTERFACE  
Synchronous Data Transfer  
Synchronous data transfer is optional and is only used data phases. It  
shall be used in a data phase if a synchronous data transfer agreement  
has been established (see SYCHRONOUS DATA TRANSFER  
REQUEST Message). The agreement specifies the REQ/ACK offset  
and the minimum transfer period.  
The REQ/ACK offset specifies the maximum number of REQ pulses  
that can be sent by the target in advance of the number of ACK  
pulses received from initiator, establishing a pacing mechanism. If  
the number of REQ pulses exceeds the number of ACK pulses by the  
REQ/ACK offset, the target shall not assert the REQ signal until  
after the leading edge of the next ACK pulse is received. A  
requirement for successful completion of the data phase is that the  
number of ACK and REQ pulses be equal.  
The target shall assert the REQ signal for a minimum of an assertion  
period. The target shall then wait at least the greater of a transfer  
period from the last transition of the REQ signal to true or a  
minimum of a negation period from the last transition of the ACK  
signal to false before asserting the ACK signal.  
The initiator shall send one pulse on the ACK signal for each REQ  
pulse received. The ACK signal may be asserted as soon as the  
leading edge of the corresponding REQ pulse has been received. The  
Initiator shall assert the ACK signal for a minimum of an assertion  
period. The initiator shall wait at least the greater of transfer period  
from the last transition of the ACK signal to true or for a minimum  
of a negation period from the last transition of the ACK signal to  
false before asserting the ACK signal.

If the I/O signal is true (transfer to the initiator), the target shall first  
drive the DB(7-0,P) signals to their desired values, wait at least one  
deskew delay plus one cable skew delay, then assert the REQ signals.  
The DB(7-0,P) signals shall be held valid for a minimum of one  
deskew delay plus one cable skew delay plus one hold time after the  
assertion of the REQ signal. The target shall assert the REQ signal  
for a minimum of an assertion period. The target may then negate  
the REQ signals within one hold time of the transition of the REQ  
signal to true. The initiator shall then respond with an ACK pulse.  
If the I/O signal is false (transfer to the target), the initiator shall  
tranfer one byte for each REQ pulse received. After receiving the  
leading edge of a REQ pulse, the initiator shall first drive the DB(7-  
0,P) signals to their desired values, delay at least one deskew delay  
plus one cable skew delay, then assert the ACK signal. The initiator  
shall hold the DB(7-0,P) signals valid for at least one deskew delay  
plus one cable skew delay plus one hold time after the assertion of  
the ACK signal. The initiator shall assert the ACK signal for a  
minimum of an assertion period. The initiator may then negate the  
ACK signal and may one hold time of the transition of the ACK  
signal to true.  
COMMAND Phase  
The COMMAND phase allows the target to request command  
information from the initiator.  
The target shall assert the C/D signal and negate the I/O and MSG  
signals during the REQ/ACK handshake(s) of this phase.  
Data Phase  
The data phase is a term that encompasses both the DATA IN phase  
and the DATA OUT phase.

DATA IN Phase  
The DATA IN phase allows the target to request that data be sent to  
the initiator from the target.  
The target shall assert the I/O signal and negate the C/D and MSG  
signals during the REQ/ACK handshake(s) of this phase.  
INTERFACE  
DATA OUT Phase  
The DATA OUT phase allows the target to request that data be sent  
from the target to the initiator.  
The target shall negate the C/D, I/O, and MSG signals during the  
REQ/ACK handshake of this phase.  
STATUS Phase  
The STATUS phase allows the target to request that status  
information be sent from the target to the initiator.  
The target shall assert the C/D and I/O signals and negate the MSG  
signal during the REQ/ACK handshake of this phase.  
Message Phase  
The message phase is a term that references either a MESSAGE IN,  
or a MESSAGE OUT phase. Multiple messages may be sent during  
either phase. The first byte transferred in either of these phases shall  
be either a single-byte message or the first byte of a multiple-byte  
message. Multiple-byte messages shall be wholly contained within a  
single message phase.  
MESSAGE IN Phase  
The MESSAGE IN phase allows the target to request that message(s)  
be sent to the initiator from the target.  
The target shall assert the C/D, I/O, and MSG signals during the  
REQ/ACK handshake(s) of this phase.

MESSAGE OUT Phase (See ANSI SCSI-2 6.1.9.2 for details)  
The MESSAGE OUT phase allows the target to request that  
message(s) be sent from the initiator to the target. The target invokes  
this phase in response to the attention condition created by the  
initiator.  
The target shall assent the C/D and MSG signals and negate the I/O  
signal during the REQ/ACK handshake(s) of this phase. The target  
shall handshake byte(s) in this phase until the ATN signal is negated,  
except when rejecting a message.  
If the target receives all of the message byte(s) successfully (i.e., no  
parity errors), it shall indicate that it does not wish to retry by  
changing to any information transfer phase other than the  
MESSAGE OUT phase and transfer at least one byte. The target  
may also indicate that it has successfully received the message byte(s)  
by changing to the BUS FREE phase (e.g., ABORT or BUS  
DEVICE RESET messages).  
The SCSI bus has two asynchronous conditions; the attention  
condtion. These conditions cause the SCSI device to perform ceratin  
actions and alter the phase sequence.  
SCSI Bus  
Conditions  
Attention Condition  
The attention condition allows an initiator to inform a target that  
the initiator has a message ready. The target may get this message by  
performing a MESSAGE OUT phase.  
The initiator creates the attention condition by asserting ATN at any  
time except during the ARBITRATION or BUS FREE phases.  
The initiator shall negate the ATN signal at least two deskew delays  
before asserting the ACK signal while transferring the last byte  
transferred in a bus phase for the attention condition to be honored  
before transition to a new bus phase. Asserting the ATN signal later  
might not be honored until a later bus phase and then may not result  
in the expected action. See ANSI SCSI-2 6.2.1 for details.

Reset Condition  
The reset condition is used to immediately clear all SCSI devices  
from the bus. This condition shall take precedence over all other  
phases and condtions. Any SCSI device may create the reset  
condition by asserting the RST signal for a minimum of a reset hold  
time.  
INTERFACE  
All SCSI devices shall release all SCSI bus signals (except the RST  
signal) within a bus clear delay of the transition of the RST signal to  
true. The BUS FREE phase always the reset condition.  
The effect of the reset condition on I/O processes which have not  
completed, SCSI device reservations, and SCSI device operation  
modes is determined by whether the SCSI device has implemented  
the hard reset alternative or the soft reset alternative (one of which  
shall be implemented) as defined in ANSI SCSI-2 6.2.2.1 and  
6.2.2.2. The hard and soft reset alternative is implemented is  
provided in the SftRe bit of the INQUIRY data. This scanner  
supports Hard Reset alternative as below.  
Hard Reset Alternative:  
1) Clear all I/O process including queued I/O process.  
2) Release all SCSI device reservations.  
3) Return any SCSI device operation modes to their appropriate  
initial conditions, similar to those conditions that would be  
found after a normal power-on reset. MODE SELECT  
conditions shall be restored to their last saved values if saved  
values have been established. MODE SELECT conditions for  
which no values have been save shall be returned to their default  
values.  
4) Unit attention condition shall be set.  
Note: I/O process queuing in (1) and parameter saving in (3) are  
not supported in this scanner.

The order in which phases are used on the SCSI bus follows a  
prescribed sequence.  
SCSI Bus Phases  
Sequences  
The reset condition can abort any phase and is always followed by  
the BUS FREE phase. Also any other phase can be followed by the  
BUS FREE phase but many such instances are error conditions.  
The additional allowable sequences shall be as shown in Figure 3.5.  
The normal progression is from the BUS FREE phase to  
ARBITRATION, from ARBITRATION to SELECTION or  
RESELECTION, and from SELECTION or RESELECTION to  
one or more of the information tranfer phases (COMMAND,  
DATA, STATUS, or MESSAGE). The final information transfer  
phase is normally the MESSAGE IN phase where a  
DISCONNECT, or COMMAND COMPLETE message is  
transferred, followed by the BUS FREE phase.

A command is communicated by sending a command descriptor  
block to the target. For several commands, the command descriptor  
block is accompanied by a list of parameters sent during the DATA  
OUT phase. The command descriptor block always has an operation  
code as its first byte and a control byte as its last byte.  
Commands (See  
ANSI SCSI-2 7)  
INTERFACE  
Reserved (See ANSI SCSI-2 7.1.1)  
Reserved bits, fields, bytes, and code values are set aside for future  
standardization. Their use and interpretation may be specified by  
future extensions to ANSI SCSI standard. A reserved bit, field, or  
byte shall be set to zero, or in accordance with a future extension to  
this standard. A target that receives a reserved bit, field, or byte that  
is not zero or receives a reserved code value shall terminate the  
command with CHECK CONDITION status and the sense key  
shall be set to ILLEGAL REQUEST.  
Logical Unit Number  
The logical unit number is defined in the IDENTIFY message. The  
target shall ignore the logical unit number specified within the  
command descriptor block if an IDENTIFY message was received.  
This scanner supports Logical Unit Number 000b only. Followings  
shows target’s response to selection of invalid logical unit.  
• In response to an INQUIRY command, the target shall return the  
INQUIRY data with the peripheral qualifier set to the value  
required.  
• In response to any other command except REQUEST SENSE, the  
target shall terminate the command with CHECK CONDITION  
status.  
• In response to an REQUEST SENSE command, the target shall  
return sense data. The sense key shall be set to ILLEGAL  
REQUEST and the additional sense code shall be set to  
LOGICAL UNIT NOT SUPPORTED.

Transfer Length  
The transfer length field specifies the amount of data to be  
transfered, usually number of blocks. The block length is this scanner  
is 1byte. In command that use multiple bytes for the transfer length,  
a transfer length of zero indicates that no data transfer shall take  
place. A value of one or greater indicates the number if blocks that  
shall be transferred.  
Allocation Length  
The allocation length field specifies the maximum number of bytes  
that an initiator has a allocated for returned data. An allocation  
length of zero indicates that no data shall be transferred. This  
condition shall not be considered as an error. The target shall  
terminate the DATA IN phase when allocation length bytes have  
been transferred or when all available data have been transferred to  
the initiator, whichever is less. The allocation length is used to limit  
the maximum amount of data(e.g. sense data, mode data, etc)  
returned to initiator.  
Control field  
The control field is the last byte of every command descriptor block.  
The control field is defined in ANSI SCSI-2 7.2.7. In this scanner,  
this field is not used. Any field in this byte is regarded as Reserved.

The sense key, additional sense code and additional sense code  
qualifier provide a hierachy of information. The intention of the  
hierarchy is to provide a top down approach for an initiator to  
determine information relating to the error and exception  
conditions. The sense key provides generic categories in which error  
and exception condition can be reported. Initiators would typically  
use sense keys for high level error recovery procedures. Additional  
sense codes provide further detail describing the sense key.  
Additional sense code qualifiers add further detail to the additional  
sense code. The additional sense code and additional sense code  
qualifier can be used by initiators where sophisticated error recovery  
procedures require detailed information describing the error and  
exception conditions.  
INTERFACE  
The sense key field is mandatory and indicates generic information  
describing an error or exception condition. The sense key used are  
defined in Table 3.29.

Table 3.29 Sense Key Descriptions  
Sense Description  
Key  
0h  
NO SENSE. Indicates that there is no specific sense key  
information to be reported for the designated logical unit. This  
would be the case for a successful command or a command that  
received CHECK CONDITION or COMMAND  
TERMINATED status because one of the filemark, EOM, or  
ILI bits is set to one.  
2h  
3h  
NOT READY. Indicates that the logical unit addressed cannot  
be accessed. Operator intervention may be required to correct  
this condition.  
MEDIUM ERROR. Indicates that the command terminated  
with a non-recovered error condition that was probably caused  
by a flaw in the medium or an error in the recorded data. This  
sense key may also be returned if the target is unable to  
distinguish between a flaw in the medium and a specific  
hardware failure (sense key 4h)  
4h  
5h  
HARDWARE ERROR. Indicates that the target detected a non-  
recoverable hardware failure (for example, controller failure,  
device failure parity error, etc.) while performing the command  
or during a self test.  
ILLEGAL REQUEST. Indicates that there was an illegal  
parameter in the command descriptor block or in the additional  
parameters supplied as data for some commands (FORMAT  
UNIT, SEARCH DATA, etc.). If the target detects an invalid  
parameter in the command descriptor block then it shall  
terminate the command without altering the medium. If the  
target detects an invalid parameter in the additional parameters  
supplied as data, then the target may have already altered the  
medium. This sense key may also indicate that an invalid  
INDENTIFY message was received  
6h  
UNIT ATTENTION. Indicates that the removable medium  
may have been changed or the target has been reset. See ANSI  
SCSI-2 7.9 for more detailed information about the unit  
attention condition.  
Bh  
ABORTED COMMAND. Indicates that the target aborted the  
command. The initiator may be able to recover by trying the  
command again.

command, the difference of the required length(Transfer Length)  
minus the actual length in bytes. (Negative values are indicated by  
two’s complement notation)  
INTERFACE  
Additional Sense Length: 0Ah(10 bytes)  
This field indicates the number of additional sense bytes to follow. If  
the allocation length of the command descriptor block is too small to  
transfer all of the additional sense bytes, the additional sense length is  
not adjusted to reflect the truncation.  
Command Specific Information: 00000000h(not supported)  
ASC (Additional Sense Code): This field indicates further  
information related to the error or exception condition reported in  
the sense key field.  
The additional sense code qualifier (ASCQ) indicates detailed

The window identifier specifies the window defined by the window  
descriptor. A window is referenced by the window identifier during  
data transfers and parameter updates.  
Fujitsu defines for duplex scanner, window identifiers 00h to 7Fh are  
used for front page and 80h to FFh are used for back page,  
implicitly. This scanner supports one window for each side,  
therefore, window identifier 00h for front page and window

The transfer length specifies the length in bytes of the window  
identifier list that shall be sent during the DATA OUT phase. A  
transfer length of zero indicates that no data shall be transferred. This  
condition shall not be considered as an error.  
The window identifier list consists of zero or more window  
identifiers each of which specifies a window to be scanned.  
This command is mandatory when scanning in duplex mode by  
sending window identifier 00h, 80h. When scanning in simplex  
mode this command is not required but it can be available. In the  
simplex mode, only 00h(front page) is specifiable.

The transfer length specifies the number of blocks the target shall  
transfer to the initiator during the DATA IN phase. The block size  
is 1 byte in fujitsu scanner. A transfer length of zero, is not  
considered an error and no data shall be transferred.  
If the target transfers less than transfer length blocks a CHECK  
CONDITION status shall be returned. The ILI bit is set to one, the  
valid bit is set to one, and the information bytes are set to the  
difference (residue) between the requested transfer length and the  
actual number of blocks transferred.  
The command shall be terminated with a status of RESERVATION  
CONFLICT if any reservation access conflict (see ANSI SCSI-2  
10.2.10) exists and no data shall be transferred.

MODE SELECT(6) Command  
The MODE SELECT(6) command (Table 3.66) provides a means  
for the initiator to specify medium, logical unit, or peripheral device  
parameters to the target. Targets that implement the MODE  
SELECT command shall also implement the MODE SENSE  
command. Initiators should issue MODE SENSE prior to each  
MODE SELECT to determine supported pages, page lengths, and

string in conjunction with Endorser String. The Endorser String  
Length of zero is not considered as error. The maximum printable  
string length in this scanner is 20 columns including endorser  
counter value. This scanner supports, only “%05ud” for endorser  
counter format. This field can be exceeded 20 because of “%%” is  
two characters but it is recognized “%” as one character.  
Endorser Strings field specifies Endorser Strings to be printed.  
Alpha-numeric(ASCII code 20h to 7Fh) and Endorser counter is  
available. This field uses C-language printf syntax. Only one  
numerical argument is available and any escape sequences are not  
available(ex. “Number of Page %05ud”[20column]). Endorser  
counter is used as numerical argument implicitly.

The status byte and status byte code are defined in Table 3.80, 3.81.  
A status byte shall be sent from the target to the initiator during the  
STATUS phase at the completion of each command unless the  
command is terminated by one of the following events:  
Status (See ANSI  
SCSI-2 7.3)  
a) an ABORT message;  
b) an ABORT TAG message; (ABORT TAG is not supported by  
this scanner)  
INTERFACE  
c) a BUS DEVICE RESET message;  
d) a CLEAR QUEUE message;(CLEAR QUEUE is not supported  
by this scanner)  
e) a hard reset condition;  
f) an unexpected disconnect.  
The STATUS phase normally occurs at the end of a command but  
in some case may occur prior to transferring the command descriptor  
block.

A definition of the status byte codes is given below.  
GOOD: This status indicates that the target has successfully  
completed the command.  
CHECK CONDITION: This status indicates that a contingent  
allegiance condition has occurred(See ANSI SCSI-2 7.6).  
BUSY: This status indicates that the target is busy. This status shall  
be returned whenever a target is unable to accept a command from  
an otherwise acceptable initiator (i.e., no reservation conflicts). The  
recommended initiator recovery action is to issue the command  
again at a later time.  
RESERVATION CONFLICT: This status shall be returned  
whenever an initiator attempts to access a logical unit or extent  
within a logical unit that is reserved with conflicting reservation type  
for another SCSI device (See RESERVE UNIT, RESERVE UNIT  
commands). The recommended initiator recovery action is to issue  
the command again at a later time (see ANSI SCSI-2 7.6).

The message system allows communication between an initiator and  
target for the purpose of interface management. A message may be  
one, two, or multiple bytes in length. One or more messages may be  
sent during a single MESSAGE phase, but a message may not be  
split over MESSAGE phase. The initiator is required to end the  
MESSAGE OUT phase (by negating ATN) when it sends certain  
messages identified in Table 3.82.

The supported extended message by this scanner is  
SYNCHRONOUS DATA TRANSFER only.  
The first message sent by the initiator after the SELECTION phase  
shall be an IDENTIFY, ABORT, or BUS DEVICE RESET message.  
If a target receives any other message it shall go to BUS FREE  
phase.(see unexpected disconnect ANSI SCSI-2 6.1.1)  
If the first message is an IDENTIFY message, then it may be  
immediately followed by other messages, such as the first of a pair of  
SYNCHRONOUS DATA TRANSFER REQUEST messages. The  
IDENTIFY message establishes a logical connection between the  
initiator and the specified logical unit or target routine within the  
target known as an I_T_L nexus to be re-established. Only one  
logical unit shall be identified for any connection; if a target receives  
a second shall go to BUS FREE phase (see unexpected disconnect  
ANSI SCSI-2 6.1.1). The treatment of other logical unit addressing  
errors is described in ANSI SCSI-2 7.5.  
Whenever an I_T_L nexus is established by an initiator that is  
allowing disconnection, the Initiator shall ensure that the current  
pointers are equal to the saved pointers for that particular logical unit  
or target routine. An implied restore pointers operation shall occur as  
a result of a reconnection.  
ABORT (Init → Targ)  
The ABORT message is sent from the initiator to the target to clear  
any I/O process for the I_T_x nexus. The target shall go to the BUS  
FREE phase following successful receipt of this message. The  
pending data, status, and I/O processes for any other nexus shall not  
be cleared.  
Previously established conditions, including MODE SELECT  
parameters, reservations, and extended contingent allegiance shall  
not be changed by the ABORT message.

BUS DEVICE RESET (Init → Targ)  
The BUS DEVICE RESET message is sent from an initiator to  
direct a target to clear all I/O processes on that SCSI device. This  
message forces a hard reset condition to the selected SCSI device.  
The target shall go to the BUS FREE phase following successful  
receipt of this message. This target shall create a unit attention  
condition for all initiators (see ANSI SCSI-2 7.9).  
INTERFACE  
COMMAND COMPLETE (Init ← Targ)  
The COMMAND COMPLETE message is sent from a target to an  
initiator to indicate that the execution of an I/O process has  
completed and that valid status has been sent to the initiator. After  
successfully sending this message, the target shall go to the BUS  
FREE phase by releasing the BSY signal. The target shall consider the  
message transmission to be successful when it detects the negation of  
ACK for the COMMAND COMPLETE message with the ATN  
signal false.  
DISCONNECT (Init ← Targ)  
The DISCONNECT message is sent from a target to inform an  
initiator that the present connection is going to be broken (the target  
plans to disconnect by releasing the BSY signal), but that a later  
reconnect will be required in order to complete the current I/O  
process. This message shall not cause the initiator to save the data  
pointer. After successfully sending this message, the target shall go to  
the BUS FREE phase by releasing the BSY signal. The target shall  
consider the message transmission to be successful when it detects  
the negation of the ACK signal for the DISCONNECT message  
with the ATN signal false.  
Targets which break data transfers into multiple connections shall  
end each successful connection(except possibly the last) with a SAVE  
DATA POINTER - DISCONNECT message sequence.  
If the target receives the DISCONNECT message from the initiator,  
the target shall respond by sending a MESSAGE REJECT message  
to the initiator.

Identify DiscPriv LUNTAR Reserved Reserved  
LUNTRN  
The Identify bit shall be set to one to specify that this is an  
IDENTIFY message.  
A disconnect privilege (DiscPriv) bit of one indicates that the  
initiator has granted the target the privilege of disconnecting. A  
DiscPriv bit of zero specifies that the target shall not disconnect. This  
bit is not defined and shall be set to zero when an IDENTIFY  
message is sent by a target.  
A logical unit target (LUNTAR) bit of zero specifies that the I/O  
process is directed to or from a logical unit. A LUNTAR bit of one  
specifies that the I/O process is directed to or from a target routine.  
This scanner supports direction to logical unit, LUNTAR bit is zero,  
only.  
The logical unit number target routine number (LUNTRN) field  
specifies a logical unit number if the LUNTRN bit is zero. The  
response to an invalid value in the LUNTRN field is described in  
ANSI SCSI-2 7.5.3.  
An IDENTIFY message is invalid if a reserved bit is set to one or if  
the LUNTAR bit is set to one, this scanner may respond to an  
invalid IDENTIFY message by immediately sending a MESSAGE  
REJECT message.  
An implied RESTORE POINTERS message shall be performed by  
the initiator prior to the assertion of the ACK signal for the next  
phase for an inbound IDENTIFY message sent during reconnection.

An implied RESTORE POINTERS message shall be performed by  
the initiator following successful identification of the nexus during  
the MESSAGE IN phase of reconnection and before the negation of  
the ACK signal for the next transfer following the successful  
identification.  
INTERFACE  
INITIATOR DETECTED ERROR (Init → Targ)  
The INITIATOR DETECTED ERROR message is sent from an  
initiator to inform a target that an error has occurred that does not  
preclude the target from retrying the operation. The source of the  
error may either be related to previous activities on the SCSI bus or  
may be internal to the initiator and unrelated to any previous SCSI  
bus activity. Although present pointer integrity is not assured, a  
RESTORE POINTERS message or a disconnect followed by a  
reconnect, shall cause the pointers to be restored to their defined  
prior status.  
MESSAGE PARITY ERROR (Init → Targ)  
The MESSAGE PARITY ERROR message is sent from the initiator  
to the target to indicate that it received a message byte with a parity  
error (see ANSI SCSI-2 6.2.1).  
In order to indicate its intentions of during this message, the initiator  
shall assert the ATN signal prior to its release of the ACK signal for  
the REQ/ACK handshake of the message byte that has the parity  
error. This provides an interlock so that the target can determine  
which message byte has the parity error. If the target receives this  
message under any other circumstance, it shall signal a catastrophic  
error condition by releasing the BSY signal without any further  
information transfer attempt.  
If after receiving the MESSAGE PARITY ERROR message the  
target returns to the MESSAGE IN phase before switching to some  
other phase, the target shall re-send the entire message that had the  
parity error.

MESSAGE REJECT (Init ↔ Targ)  
The MESSAGE REJECT message is sent from either the initiator or  
target to indicate that the last message or message byte it received was  
inappropriate or has not been implemented.  
In order to indicate its intentions of sending this message, the  
initiator shall assert the ATN signal prior to its release of the ACK  
signal for the REQ/ACK signal for the REQ/ACK handshake of the  
message byte that is to be rejected. If the target receives this message  
under any other circumstance, it shall reject this message.  
When a target sends this message, it shall change to MESSAGE IN  
phase and send this message prior to requesting additional message  
bytes from the initiator. This provides and interlock so that the  
initiator can determine which message byte is rejected.  
After a target sends a MESSAGE REJECT message and if the ATN  
signal is still asserted, then it shall return to the MESSAGE OUT  
phase. The subsequent MESSAGE OUT phase shall begin with the  
first byte of a message.  
NO OPERATION (Init → Targ)  
The NO OPERATION message is sent from an initiator in response  
to a target’s request for a message when the initiator does not  
currently have any other valid message to send.  
For example, if the target does not respond to the attention  
condition until a later phase and at that time the original message is  
no longer valid the initiator may send the NO OPERATION  
message when the target enters the MESSAGE OUT phase.

RESTORE POINTERS (Init ← Targ)  
The RESTORE POINTERS message is sent from a target to direct  
the initiator to copy the most recently saved command, data, and  
status pointers for the I/O process to the corresponding current  
pointers. The command and status pointers shall be restored to the  
value at the beginnings of the data area in the absence of SAVE  
DATA POINTER message or to the value at the point at which the  
last SAVE DATA POINTER message occurred for that nexus.  
INTERFACE  
This scanner sends this message only when received a INITIATOR  
DETECTED ERROR during image data transfer.  
SAVE DATA POINTER (Init ← Targ)  
The SAVE DATA POINTER message is sent from a target to direct  
the initiator to copy the current data pointer to the saved data  
pointer for the current I/O process.(ANSI SCSI-2 6.4 for a  
definition of pointers.)

A SYNCHRONOUS DATA TRANSFER REQUEST (SDTR)  
message (Table 3.87) exchange shall be initiated by an SCSI device  
whenever a previously arranged data transfer agreement may have  
become invalid. The agreement becomes invalid after any condition  
which may leave the data transfer agreement in an indeterminate  
state such as:  
a) after a hard reset condition;  
b) after a BUS DEVICE RESET message and;  
c) after a power cycle.  
In addition, an SCSI device may initiate an SDTR message exchange  
whenever it is appropriate to negotiate a new data transfer agreement  
(either synchronous or asynchronous). SCSI devices that are capable  
of synchronous data transfers shall not respond to an SDTR message  
with a MESSAGE REJECT message.  
The SDTR message exchange establishes the permissible transfer  
periods and the REQ/ACK offsets for all logical units on the two  
devices. This agreement only applies to data phases.  
Transfer Period Factor:  
62(4MB/s max.) to 255  
The transfer period factor times four is the value of the transfer  
period. The transfer period is the minimum time allowed between  
leading edges of successive REQ pulses and of successive ACK pulses  
to meet the device requirements for successful reception of data.  
REQ/ACK Offset:  
0(Async), 1 to 8  
The REQ/ACK offset is the maximum number of REQ pulses  
allowed to be outstanding before the leading edge of its  
corresponding ACK pulse is received at the target. This value is  
chosen to prevent overflow conditions in the device’s reception  
buffer and offset counter. A REQ/ACK offset value of zero shall  
indicate asynchronous data transfer mode; a value of FFh shall  
indicate unlimited REQ/ACK offset.

The originating device (the device that sends the first of the pair of  
SDTR message) sets its values according to the rules above to permit  
it to receive data successfully. If the responding device can also  
receive data successfully with those values (or smaller transfer periods  
or larger REQ/ACK offsets or both), it returns the same values in its  
SDTR message. If it requires a larger transfer period, a smaller REQ/  
ACK offset, or both in order to receive data successfully, it  
substitutes values in its SDTR message as required, returning  
unchanged any value not required to be changed. Each device when  
transmitting data shall respect the limits set by the other’s SDTR  
message, but it is permitted to transfer data with larger transfer  
periods, smaller REQ/ACK offsets, or both than specified in the  
other’s SDTR message. The successful completion of an exchange of  
SDTR message implies an agreement as follows:  
INTERFACE  
Responding Device SDTR response Implied Agreement  
1) Non-zero REQ/ACK offset  
Each device transmits data with a  
transfer period equal to or greater  
than and a REQ/ACK offset equal  
to or less than the values received in  
the other device's SDTR message.  
2) REQ/ACK offset equal to zero  
3) MESSAGE REJECT message

This chapter describes about command and phase sequence related  
to host system. SCSI-2 introduced PHASE, MESSAGE system, etc.,  
for interfacing other than simple command passing, therefore, a lot  
of sequences can be considerable. Below shows some typical case and  
out recommendations of implementation SCSI protocol to the  
system.  
Command  
Sequence  
System Initialization  
The following list of information is assumed necessary and sufficient  
for normal system initialization:  
1) A list of each installed and powered on SCSI device for each SCSI  
address. SCSI devices that are not powered on are treated as not  
installed, assuming that the terminators are powered from a  
source other than unexpected SCSI devices.  
2) A list of the installed logical units for each SCSI device.  
Unpowered or failing logical units may not be completely  
identifiable.  
3) The device type for each available logical unit.  
4) The manufacturer and model for each available logical unit. (this  
information may not be available for SCSI-1 devices)  
5) The critical device type information for each available logical  
unit.  
6) This information varies depending on the device type.  
7) Extended functionality of SCSI devices such as target role  
capability in  
8) devices that are principally initiators, AEN capability, etc.  
The following states are established for each attached logical unit that  
has power available and is not failing:  
1) The ready state for each available logical unit, including any  
required medium initialization, but not initialization, but not  
formatting.  
2) All error conditions associated with the starting process are  
cleared.  
3) All UNIT ATTENTION conditions are cleared.  
4) All data transfer parameters are established.  
3-110  
M3099GX/GH OEM Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
5) All pertinent system tuning parameters are established where  
known. Note that these may be modified dynamically to improve  
the performance characteristics of the system.  
The following procedures show the sequences necessary to  
implement a system that initializes itself with a minimum of  
information available at power on time. Many real systems are not so  
generalized, having considerable information available about the  
proper configuration at power-on time. In those cases, the sequence  
steps that would have been necessary to obtain that predefined  
information may be skipped or ignored.  
INTERFACE  
General Procedure for Initializing Devices  
Initiator Activities:  
Power On: It is assumed that each SCSI device, as it is powered on,  
performs appropriate internal reset operations and internal test  
operations. Once powered on, initiators that have target capability  
should be prepared to respond to a selection within a system-specific  
time.  
Reset: At power-on time, it is likely that an SCSI device has caused  
errors to the ongoing activities on the SCSI bus. A bus reset should  
be generated to notify attached devices that any activities that may  
have been occurring should be restarted .  
Find Device: Each SCSI address other than the initiator’s SCSI  
address should be tested to determine if an SCSI device responds. If  
an SCSI device responds, an INQUIRY command to logical unit 0  
should be executed. The information obtained indicates the device  
type, manufacturer, and model of the attached logical unit 0 if the  
response data format field is one or two. If the response data format  
field is zero, only the device type field is valid. In addition, the  
version of command set supported by the device is indicated by the  
ANSI-approved version field.  
M3099GX/GH OEM Manual  
3-111  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Find logical units: Each possible logical unit number on the attached  
targets should be tested for experience using an INQUIRY  
command. Those found with a non-zero peripheral qualifier in the  
INQUIRY data should not be included in the list of available logical  
units. Each available logical unit should be added to the host  
configuration information, identifying the associated logical unit  
number, device type, manufacturer, and model.  
Verify State: The verify state test should be made to clear any  
outstanding errors, capture and clear UNIT ATTENTION  
conditions, and determine the state of readiness of the available  
logical units. The logical units should be identified as ready, not  
ready, or failing by this test.  
Device Initialization: The device undergoes a device-dependent  
initialization process. This process is described for direct-access  
devices, sequential-access devices, and processor devices. Other  
device initialization procedures are not described since they tend to  
be similar to one of these initialization procedures. The initialization  
process takes into account the state of the device as identified during  
the verify state test.  
Device On-line: The successful completion of the device  
initialization process allows the device-table entry to be fully enabled.  
The device joins the system with all key parameters identified and  
initialized. The device state is known and may be presented to the  
system operator.  
Verify State Test  
The verify state test uses the following steps to identify any  
outstanding errors, clear any UNIT ATTENTION conditions, and  
determine the readiness of the devices. The verify state test should be  
executed against each available logical unit.

ATTENTION condition or other error was successfully cleared. In  
some special cases, another error may have been nested with the  
UNIT ATTENTION and this TEST UNIT READY command  
may also return CHECK CONDITION status.  
REQUEST SENSE (4):  
This REQUEST SENSE command is used to determine which error  
or exception was associated with the CHECK CONDITION status  
returned by the TEST UNIT READY (3) command. In addition,  
this REQUEST SENSE command is used to clear the outstanding  
CHECK CONDITION. This may be a NOT READY sense key or  
another unexpected error.  
TEST UNIT READY (5):  
This TEST UNIT READY command is used to see if all outstanding  
CHECK CONDITION statuses have finally been cleared. If so, the  
logical unit is identified as ready.  
REQUEST SENSE (6):  
This REQUEST SENSE command is used to determine why there is  
a persistent CHECKCONDITION status. If the sense key indicates  
some other failure, the logical unit is identified as failing and the  
sense key is logged in the appropriate area. IMPLEMENTORS  
NOTE: Commands that receive BUSY or RESERVATION  
CONFLICT status should be re-issued until some other status is  
received.

Duplex Scanning  
The duplex scanning is extension of simplex mode scanning.  
For duplex scanning, SET WINDOW command must specify front  
side window (window identifier 00h) and back side window  
(window identifier 80h) in window descriptor. SCAN command is  
required to invoke duplex mode scanning by sending window  
identifier 00h, 80h in data out phase. READ command is issued to  
read image data sequentially front window and back window. In the  
READ command, window identifier field must be specified in data  
type qualifier field to distinguish which side of window data is read.  
When front image data is completely read, back image data can be  
read in this scanner.  
Reserve exclusive use of the scanner.

Notes: 1. If the requested Transfer Length does not equal to  
actually transferred data size, the scanner returns CHECK  
CONDITION status and create Sense Data as bellow.  
ILI = 1 :  
INFORMATION : TL(requested Transfer Length) -  
actual transferred data size  
INTERFACE  
This status is sent to the latest READ command. For the  
other READ commands, the GOOD status will be  
returned. If requested Transfer Length in last READ  
command equal to the data size that should be  
transferred, CHECK CONDITION status will be  
returned to next READ command.  
2. In addition to Note 1, when completion of image data  
transfer, the scanner sets EOM bit to 1. If initiator issues  
REQUEST SENSE command for each READ command,  
Sense Key will be set to NO SENSE but by checking  
EOM bit completion of transfer can be detected.  
EOM = 0 : Image data transfer is not completed.  
EOM = 1 : Image data transfer has just completed.  
Above specification is described in JBMS but it is not  
recommended for speed performance reason.  
3. After all image data of the window is transferred,  
CHECK CONDITION status will be returned following  
each READ commands. To scan another document, issue  
SET WINDOW command and set window.  
4. Enabling or disabling disconnection is depending on  
IDENTIFY message related to READ command. If bit 6  
of IDENTIFY message is 1, disconnection is enabled. If  
bit 6 of IDENTIFY message is 0, disconnection is  
disabled.

Document  
Quality  
This section provides document types and weights available for the  
scanner, with precautions.  
Document type  
The recommended paper type for document is as follows:  
NOTICE  
Use specified paper only. (In rare occasion, double feeding may  
occur or document damage may occur.)  
• Fine paper  
• Plain paper (For example the paper specified for XEROX 4024)  
• OCR paper  
When using all other type paper, check that it is successfully fed by  
ADF before performing a reading operation.  
Ream weight  
The ream weight is as follows:  
• 45 to 110 kg (13.9 to 34 lb, 52 to 127 g/m2)  
Note:  
Ream weight is a weight of 1000 sheets of paper whose size is 788  
mm x 1091 mm.  
Precautions  
Be careful to scan the following documents. Preliminary document  
feed test may be necessary to avoid the unexpected errors. If the  
document slips in ADF (JAM error) or double feed occurs,  
separation pressure adjustment of Appendix C may be effective.  
CAUTION  
Never use an original document on this machine.  
• Paper has clip  
• Paper has ink, etc. is not dry.

NOTICE  
Do not feed important original document so as not damage it in  
rare case.  
When scanning a translucent document, set the density to light  
mode.  
To prevent roller smudging, avoid scanning a document filled out in  
pencil. Clean the roller as often as possible when scanning many  
document. Once every 1000 pages is recommended.  
The chemical composition of some carbonless papers reacts with the  
roller rubber and damages the rubber. Check the carbonless papers  
before use.  
The carbonless papers may be used if:  
1. Ream weight is 44 kg (12 lb) or more  
2. Hopper load is 500 sheets or fewer

Glossary of Terms  
A4 size  
A standard paper size used in Japan and other countries. Paper is  
210 x 297 mm (8.25 x 11.6 inches).  
ASCII  
The acronym for American Standard Code for Information  
Interchange. ASCII is a set of 256 codes (numbered 0 to 255) used  
to communicate information between a computer and another device  
such as a scanner.  
Automatic separation  
The image processing method to detect the difference between text  
and photos and choose the thresholding accordingly. Automatic  
separation allows the scanner to switch between line mode and half  
tone mode in one pass.  
Automatic start mode  
A mode that the scanner starts to read by the command from the  
host machine.  
Bit  
The smallest unit of information in computer memory. A bit is a  
single digit, either a 1 or a 0, in the binary numbering system. Eight  
bits equal one byte.  
Dither  
GLOSSARY OF  
TERMS  
Technique for producing halftone images representing the entire  
grayscale using two pixel levels black and white.  
dpi  
Dots per inch.

Endorser  
The unit for printing characters before or after scanning. These  
characters may be used for collation of the documents and the image  
data. (See appendix A)  
Equipment error  
An error which the operator can not recover, such as optical system  
alarm, temperature alarm and so on. It is necessary to make contact  
manufacturer's authorized service center for paper repair service.  
Error diffusion  
High-quality halftone (pseudo-grayscale) image production base on  
black-and-white pixel binarization. A pixel's optical density and that  
of adjacent pixels are summed, with black pixels relocated in their  
order of density as they relate to adjacent pixels.  
The purpose of this technique is to minimize the average error  
between readed and printed densities. Density data for adjacent  
pixels is modified by diffusing errors on the objective pixel into  
several pixels, which are than binarized. This maintains high  
grayscale levels and resolution during reading, while suppressing  
moire patterns by dotted halftone images such as newspaper photo  
graphs.  
Filtering  
The quality of images written in pencil or ballpoint pen and readed  
depends on the reflective light characteristics of the ink or lead.  
Dropped pixel's may produce out lines, gaps, or thin, barely  
connected lines due to even optical density. Filtering detects areas  
lighter than their surroundings and increases their density to improve  
image clarity.  
Hexadecimal  
A base-16 numbering system (also commonly referred to as hex  
numbers). Since a base-16 system requires 16 digits, numbers 0  
through 9 and letters A through F are used. It is convenient to  
express binary numbers in hexadecimal because fewer digits are  
required.  
GL-2  
M3099GX/GH OEM Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Image emphasis  
Density is decreased for lighter but not completely white areas  
adjacent to black areas. Weakening this emphasis eliminates spot  
noise or produces softened images.  
Interface  
The connection that allows communication from one part of a  
system to another. For example, electrical signals are transferred  
between the computer and scanner over an interface cable.  
Inversion (Reverse-image reading)  
In reverse-image reading, data is changed from black to white and  
vice versa.  
IPC II  
Image processing option of this scanner.  
Letter size  
A standard paper size used in the U.S.A. and other countries. Paper  
is 8-1/2 x 11 inches (215.9 x 279.4 mm).  
Manual mode  
A mode that the operator can put the document on the hopper one  
by one. A document on the hopper can be read automatically.  
Manual start mode  
A mode that the scanner starts to read by pressing the “START”  
button on the operator panel.  
GLOSSARY OF  
TERMS  
Mirror image  
The readed image is symmetrically flipped to produce a mirror image  
of the original detected in the main scanning direction.  
Noise removal  
Isolated noise from an image appearing as black spots in white areas  
and voids in black areas is removed to improve image quality.

Operator panel  
A panel containing the scanner indicators and buttons. The operator  
panel is used to control scanner operations such as loading document  
selecting features, and changing setup options.  
Outline extraction  
The boundary between black and white areas is traced and the  
outline extracted for closed areas.  
RS-232C interface  
A type of serial interface. See Serial interface.  
Serial interface  
A standard computer interface. Information is transferred between  
devices over a single wire (although other wires are used for control).  
With a serial interface, an interface cable greater than 3 meters (10  
feet) can be used. This is often necessary in networking  
environments, where the scanner may be shared.  
Smoothing  
Smoothing eliminates jaggies from slanted lines and curves. Irregular  
convexities are deleted and irregular concavities filled in. This is  
useful in OCR applications, for example.  
Temporary error  
A status which the operator can recover, such as paper jam, hopper  
empty, cover open, pick miss.
