2-3. Handling Notes  
(1) Install the printer near an easily accessible socket-outlet.  
(2) Place the unit on a flat and stable surface for operation.  
(3) Do not connect the AC Power Plug to the same outlet used for other noise  
generating devices (large motors, etc.).  
(4) Be careful not to drop paper clips, pins and other foreign objects into the  
unit.  
(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use  
Lacquer thinner, Trichlorethelene or Ketone solvents because they may  
damage plastic parts.  
(6) Use a soft brush, etc. for cleaning the printer mechanism and PCB.  
(7) Keep hands out of printer while power is on.  
(8) Do not attempt to print when there is no ink ribbon or paper in the unit. The  
print head life could be severly reduced.  
(9) If the paper is fastened tightly to the roll, the paper may not detach from the  
roll when the end is reached.  
If this happens, the no paper detection function and paper feed will not  
operate.  
(10) Always keep the printer cover attached when printing to prevent paper  
jams, noise, and other problems.  
(11) Always turn the power off before opening the printer cover. (e.g. When  
renewing a ink ribbon)

(4) POWER Lamp  
(5) ON LINE Lamp  
Connect to an outlet of the specified voltage.  
Supplies DC 12V power to the printer.  
Protects the printer against dust and reduces noise.  
Lights up (green LED) when power is on.  
Lights up (green LED) when the unit is in the online  
mode.  
(6) ALARM Lamp  
Lights up (red LED) when printer operation is not  
normal, or the printer is out of paper. It is necessary  
to install paper into the printer and press the ON  
LINE Button to recover from paper empty status.  
Turn off the printer power in order to recover from  
abnormal operation.  
(7) ON LINE Button  
(8) FEED Button  
Toggles between the on-line and off-line modes. The  
printer will go on-line after turning power on.  
Momentary operation of this button provides one  
line feed. Pressing this button continuously will  
cause continuous paper feed. If power is turned on  
while pressing this button, self printing*1 will be  
performed.  
(9) Interface Connector Connects the printer to host computers. Check that  
both computer and printer are off before connecting.  
(10) DIP Switches  
Allows for setting of various functions according to  
user requirements.  
(11) Peripheral Drive  
Output  
Connects the printer to the peripheral devices such  
as Cash Drawer, Paper Cutter and Paper Take-Up  
Device etc. to drive them.  
*1 Self Printing  
This printer has another convenient function, the  
Automatic Test Printing. With the ink ribbon and  
paper properly installed in the printer, turn the power  
ON while holding down the Feed switch. Test print-  
ing will start and stop again automatically.

4. INSTALLATION OF INK RIBBON AND PAPER  
4-1. Installation of Ink Ribbon  
(1) Turn power off, lift the Printer Cover up and remove it.  
Note: Be careful not to touch the print head immediately after printing,  
because it can get very hot.  
Figure 4-1. Printer Cover Removal  
(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.  
Hold the ribbon taut as shown with the drive pins facing down and slide the  
ribbonbetweentheprintheadandtheplaten. Whilekeepingtheribbontaut,  
wrap one side around the black ribbon guide on the end of the platen and  
droponespoolonthespoolshaft. Asyoumovethespooldownwards, move  
the detecting lever aside to allow the spool to drop into place. Make sure the  
spool drive pins engage with the spool drive holes. As the spool drops into  
place there will be a click.  
(3) While continuing to hold the ribbon taut, install the remaining ribbon spool  
in a similar fashion.  
(4) Turn the spool that rotates freely to take up the ribbon slack.

GS  
(1D)H  
CODE  
Validation printing instruction  
FUNCTION  
OUTLINE  
This code causes the printer to perform validation printing  
of a maximum of 32 subsequent characters (at 15 CPI, from  
the thirteenth to the forty-forth column).  
After the GS code is received, a maximum of 32 characters  
should be input, followed by the LF code which indicates  
the end of the validation printing data.  
(At this time, control codes except FS, ENQ, CAN and SUB  
codes, or any character received beyond the limit of 32  
characters are ignored.)  
When the printer enters the validation mode, the ribbon is  
shifted up and the ON-LINE lamp blinks. (This lamp goes  
on and off at a 0.5-second interval until the end of the va-  
lidation mode.) Afterthematerialtobevalidatedisinserted,  
and the LF button is pressed, the validate line is printed,  
followed by a single line feed. When the check is removed  
and the ON-LINE button is pressed, the printer returns to  
regular mode and is set to ON-LINE status.  
1) The print settings by commands (such as emphasized  
mode and underline mode) are invalid only during val-  
idation printing.  
REMARKS  
2) When the CAN code is received in the validation mode,  
the printer returns to regular mode, and the mechanism  
is initialized.  
3) If the FS or SUB codes is received in the validation  
mode, these codes are executed just after the printer  
returns to regular mode.  
4) In the validation mode, the LF button and the ON-LINE  
button do not work except the above behavior.  
5) If the printer has a Red black ribbon installed, the va-  
lidate line will be printed in red.

Signals when data is ready to be read.Signal  
gose from HIGH to LOW (for at least 0.5  
microsec.) when data is available.  
These signals provide the information of the  
first to eighth bits of parallel data.Each signal  
is at HIGH level for a logical 1 and at a LOW  
level for a logical 0.

When this signal goes LOW, the printer is ready  
to accept data. When the printer is in one of  
the conditions below.”HIGH” is set.

7-5. Peripheral Unit Drive Circuit  
The Control Board of this printer is equipped with a circuit for driving peripheral  
units (Paper Cutter, Take-Up Device, Cash Drawer, etc.)  
The 6P Modular Jack is used as the Drive Circuit. When using this circuit,  
connect the peripheral unit cable to the 6P Modular Jack (cable is not included).  
Note: Peripheral unit drive circuit connector only connects to peripheral units  
such as cash drawers, etc.Do not connect it to a telephone.

Note: Make sure that the metal structural parts of the peripheral device are  
connected to frame Ground (Pin 1) to provide a static drain path.  
2. Control code  
Codes for Drive Circuit control are ESC BEL n1 n2, BEL, FS and SUB.  
Refer to the Control Codes in Section 5.  
7-6. Error Condition Alarm Mode  
If an error condition is detected during operation, the printer will stop printing  
and cause the ERROR signal to go Low. All solenoids & motors will be de-  
energized. It is necessary to turn the printer power off and on again in order to  
recover from the alarm mode.  
The printer can detect the following error conditions:  
a. Motor Lock  
b. Defective timing detector  
c. Micro-processor out of program sequence

8. WHEN POWER IS SUPPLIED BY THE USER  
When printer power is supplied by the user rather than through the accessory  
power source unit, please be careful of the following points.  
+10%  
–5%  
Note 1: The power supply must be +12V  
2A or above. An electrolytic ca-  
pacitor (C = 4700µF/25V to 6800µF/25V) must be connected across  
the output of the power supply.  
Note 2: A DC power plug is available as an option.  
Reference: Design the power supply referring to the power supply circuit shown  
below.  
Note: A line noise filter must be used to prevent line transients from passing  
through power supply. Filter design to be determined by environmental  
noise requirements.
