Removing Printed Output  
Removing printouts from the printer can be as simple as taking hold of the paper and pulling it from the printer.  
This process varies slightly depending on whether your printer uses paper supplied on rolls for the MLP 3040 or  
MLP 3040 LP models, or in cassettes for the MLP 3040 SL models.  
MLP 3040 and MLP 3040 LP Models  
These models make use of a serrated tear bar where the paper exits the printer. In most cases, the host  
application program will issue a Form Feed that will eject the paper so that all the printed information is fed out  
of the printer and the receipt or label is ready to be torn off. If all the printing is not yet out of the printer and  
the host has finished sending data to the printer, the paper may be positioned for tearing by simply pressing the  
Paper Feed Button.  
To tear the paper, pull the paper against the tear bar at a slight angle as shown in Figure 7, and then continue to  
pull the paper in the direction shown to tear it off.

Printer Configuration  
Figure 7 - Tearing Off Printed Output  
MLP 3040 SL Models  
The MLP 3040 SL models use cassettes of cut sheet receipt paper. In most cases, the host application program  
will issue a Form Feed that will eject the sheet currently being printed so that it is ready for the user to simply  
pull out of the printer. If the sheet has not been ejected and the host has finished sending data to the printer, the  
paper may be ejected by pressing the Paper Feed Button.  
Battery Charging  
The MLP 3040 contains battery monitoring and charging circuitry so that the battery may be charged while still  
in the printer. Charging the battery in the printer requires an optional power supply. Psion Teklogix offers  
power supplies for use with 100-240VAC/50-60Hz and 12/24VDC for vehicle applications.  
Optional external battery chargers are also available so that you can have fully charged batteries “standing by”  
when needed.  
The printer’s battery status is displayed in the lower right corner of the front panel LCD Display. The status is  
displayed as a battery shape which indicates the relative capacity that remains as indicated below.  
Fully Charged  
Discharged  
To charge the battery inside the MLP 3040, connect the power supply to the appropriate source, and connect the  
output of the supply to the printer’s power connector shown in Figure 8.  
Caution: Only use Psion Teklogix power supplies to power your printer and charge batteries. Other power  
supplies may damage the electronics and printing mechanism. Damage caused by use of a non-Psion  
Teklogix power supply will not be covered by the printer’s warranty.

Printer Configuration  
Power Connector  
Battery Indicator  
Figure 8 - MLP 3040 Power Connector & Battery Indicator  
When the power supply is connected, the printer’s charging circuitry will determine if the battery currently  
requires charging and if so, will turn on the Battery Indicator until the battery has reached sufficient charge.  
Depending on the condition of the battery, charging may take up to 2½ hours to complete.  
Leaving the power supply connected to the printer will cause the printer to continuously monitor the condition  
of the battery and keep the battery charged.  
For more information regarding battery charging, battery life and battery disposal, refer to “Battery Care” on  
page 40.  
Using the Magnetic Card Reader  
The optional Magnetic Card Reader (MCR) is used by some applications to read information from credit cards,  
drivers licenses, etc.  
When the host system sends a request to the MLP 3040 to enable the Magnetic Card Reader, “Swipe Card  
Now” will be displayed and the MCR Indicator will flash to indicate that the card may now be passed through  
the MCR slot, or “swiped”. Refer to Figure 9 for the card orientation and note the position of the magnetic  
strip.  
MCR Indicator

Printer Configuration  
If the card is read successfully, a short beep will sound, “Card Read Ok” will be displayed and the MCR  
Indicator will stop flashing and remain on briefly to indicate success as the data is sent to the host system.  
If the card is not read successfully, a longer error tone will sound, “Card Not Read” will be displayed and the  
Error Indicator will also begin to flash. If the read operation is not cancelled by the host application within a  
few seconds, the Error Indicator will stop flashing and the printer will return to the “Swipe Card Now”  
mode. At this time the card may be swiped again to attempt a successful read.  
The length of time allowed before the timeout is specified by the host application program. Once a timeout  
occurs, the Error Indicator will turn on momentarily and “MCR Timeout” will be displayed.  
Additional Messages  
Check Paper  
This message is displayed and the Error Indicator flashes whenever the printer runs out of print media. This  
may also occur if there has been a paper jam that prevents paper from feeding into the print head. To clear the  
error, first clear the jam and/or install new media. For information on how to replace the media supply or to  
check for a possible jam, please refer to “Installing Media” on page 4 in the Getting Started section of this  
manual.  
Next, momentarily press the Paper Feed Button to resume printing. After the error has been cleared, printing  
may resume differently depending on the model printer you are using.  
In the MLP 3040 and MLP 3040 LP models with printer firmware prior to version 2.8, printing will begin again  
where it left off. If the printer has firmware version 2.8 or later, the printer will perform a Form Feed and then  
reprint the last print job. If the entire job does not print as expected, the host program may need to be modified  
to make use of the printer’s buffer commands. Please refer to the MLP Series & PrintAbout Programmer’s  
Manual for more information.  
In the MLP 3040 SL model, printing will restart at the beginning of the current page. If the Check Paper error  
occurred at the beginning of a page, the printer will load a page from the new cassette and continue. If, for  
some reason, the Check Paper error occurred mid page, the printer will reprint the entire page after a new  
cassette has been loaded.  
It is also possible that a false paper error may be detected when using “black mark” sensing on preprinted  
forms. This condition should not occur unless the size of the black mark on the form is larger than the size  
allowed for in the host application program. Please refer to the MLP 3040 Series Programmer’s Manual for  
more information.  
Paper Door Open  
This message is displayed and the Error Indicator flashes when the printer is attempting to print and the  
Paper Door is not fully closed. To correct this error, make sure that the media is loaded properly, close the  
Paper Door, and momentarily press the Paper Feed Button.

Introduction To Setup  
The MLP 3040 series printers feature an easy to use control panel “Setup” menu system for setting permanent  
configuration parameters. These menus offer many useful and necessary features, but are typically only used  
when first setting up the printer. They are rarely used in normal everyday operation. The values that are set are  
used as the “defaults” whenever the printer is turned on or reset by the host system. Application programs often  
send commands that may override any of these values.  
As an alternative to using the Setup Menus described below, you may also use the “MLP Setup” remote  
configuration utility. This utility runs on a Windows Desktop system and connects to the printer’s serial port.  
Setup Basics  
LCD Display  
Power Indicator

When in Setup, the top line of the LCD Display shows the name of the menu or the name of a “feature” within  
the menu. The bottom line of the display shows the current value that is set to be used for the item displayed on  
the top line.  
The Setup menus operate as a “What You See Is What You Get” system. This means that whenever you view  
or change any of the menu choices available, the value showing when you proceed to the next item or exit Setup  
is the value the printer will use after you exit Setup. Note that when exiting Setup, you may elect to discard any  
changes.

Setup may be exited by pressing the Advance Button until “Exit Setup” is displayed on the top line of the  
LCD Display, and “Save Changes” is displayed on the bottom line. To save any changes you have made  
and exit Setup press the Enter Button. If feature values were changed, “Exiting Menus Saving  
Changes” will be displayed. If no values where changed, “Exiting Menus No Changes” will be  
displayed.  
If you do not want to save the changes you have made, press the Increment Button to display “Discard  
Changes” on the bottom line and then press the Enter Button. Exiting Setup No Changes” will be  
displayed.  
After Setup is exited and any changes saved, the printer will reset and reinitialize itself to adopt any changes  
that may have been made. Note that when this reset occurs, any data that may have been in the input buffer will  
be discarded.

Printer Configuration  
Format Menu  
FORMAT MENU  
Current Format  
The MLP 3040 supports five “Formats” or sets of printing parameters that may be selected either through the  
control panel or by host application programs. These Formats include printing related features such as Form  
Length, Font, Character Pitch, Margins, etc. Each Format also includes the ability to name the Format with a  
name such as “Receipt”, “Routing Label”, or “Shipping Label”, etc.  
Upon entering Setup as described earlier in “Setup Basics”, the Format Menu is the first menu that will appear.  
The bottom line of the display shows the Format that is currently selected. If you wish to change to a different  
format, press the Increment Button until the desired Format is displayed.  
Note: If you wish to use more than one Format, you must first enable additional Formats. Please refer to  
the “Max Format” feature in the “Options Menu” on page 29.  
Once the desired Format is displayed, you may do one of the following:  
press the Enter Button to review and/or change the features related to the displayed Format, or  
press the Advance Button to advance to the INTERFACE MENU  
Pressing the Enter Button will advance through the following features for the selected Format in the order  
listed below.  
Format Name  
Format 1  
Format Name  
Possible Values: Up to 16 characters of A through Z, 0 through 9, SPACE  
When shipped from the factory, the name for each format will be “FORMAT 1”, “FORMAT 2”, etc. This  
name may be changed to any combination of capital letters (A-Z), numerals (0-9), or spaces. The name may be  
up to 16 characters in length.  
To advance through the character positions of the name, press the Advance Button. To change the character  
at the current position, press the Increment Button. The order of characters that may be selected is  
“ABCDEFGHIJKLMNOPQRSTUVWXYZ SPACE 0123456789”. The name will automatically be centered

This feature selects the default font and character pitch.  
Spacing  
3 Lines  
Spacing  
Possible Values: 0 … 3* … 10 Lines  
When printing text, this feature sets spacing between lines. The height of a complete line, or line pitch, is  
determined by adding the vertical size of the current font to the Spacing. With Spacing set to the default value  
of “3” and using a font that is 23 rows high, the line pitch would be 3 + 23, or 26 dot rows. Since each dot row  
is 0.125mm, 26 x 0.125 yields a line pitch of 3.25mm or 7.8 lines per inch. This line pitch value also  
determines the amount of paper motion performed when an ASCII Line Feed character is received by the  
printer.  
When printing PC Line drawing characters, Spacing should be set to “0” to avoid space between rows of  
characters used to draw vertical lines.  
When printing graphic data, Spacing has no affect so that multiple lines of graphics may print adjacent to each  
other.  
Left Margin  
0.0000”  
Left Margin  
Possible Values: 0.0000”* … 1.0244” in increments of 0.0394”  
This feature sets the left margin in inches relative to the leftmost printing position. The left margin must be less  
than the right margin.

Printer Configuration  
Right Margin  
0.0000”  
Right Margin  
Possible Values: 0.0000”* … 1.2608” in increments of 0.0394”  
This feature sets the right margin in inches relative to the rightmost printing position.  
Text characters that would have printed to the right of the margin will either be “wrapped around” and printed  
on the next line, or will be discarded based on the setting for “Truncate Lines” in the Options Menu.  
Graphic data that would have printed to the right of the margin will be truncated.  
Note: The MLP 3040 has a maximum print width of 4.1”. However, when Mt3 Emulation has been  
selected, the Right Margin will begin indenting from a maximum print width of 2.84” to match the  
characteristics of the Psion Teklogix Mt3 Series printers.  
Print Contrast  
0
Print Contrast  
Possible Values: -75 … 0* … +125 in increments of 5 (+35* for LP Models)  
The printer automatically adjusts the amount energy used in order to maintain constant print quality as the  
battery discharges during use. The Print Contrast setting modifies the value that is determined to be needed by  
the printer and may be used to obtain improved print quality on different qualities of thermal print media.  
Note: By affecting the relative amount of battery energy that is used when printing, the Print Contrast  
setting affects both print speed and battery life. Setting a lower value will result in faster printing  
and will extend normal battery life. Setting a higher value may allow the use of poorer quality media  
and will result in slower printing and a shorter battery life.  
Max Paper Speed  
3.30 ips  
Maximum Paper Speed  
Possible Values: Standard Roll Feed Models – 0.32 …3.30* ips  
LP Models – 0.32 … 2.30* … 3.30 ips  
SL Models – 0.32 …2.30* ips  
This feature may be used to reduce the maximum paper speed if necessary to allow the printer to use heavier  
papers, labels, narrow paper or labels, or some coated papers that have a more slippery finish.  
FFeed Distance  
1.2608  
Form Feed Distance  
Possible Values: 1.0000 … 1.2608* … 2.5216 inches

Interfacing To A Host Computer  
Every MLP 3040 is equipped with an RS-232C Serial Interface. Optional factory installed interfaces are also  
available for IrDA (Infrared), Bluetooth®, and Wi-Fi®. When the printer is equipped with one of the optional  
interfaces, the interface that is selected in the Interface Menu as described on page 21 is the one that will be  
active and the other interface will be ignored.  
Note: To print out configuration information for the currently selected interface, you may press and hold  
the Enter Button until “Printing Setup” is displayed.  
Note: To switch back-and-forth between the RS-232C Serial interface and an optional interface (if  
installed), you may continue to the Enter Button until “Interface Now ‘interface’” is displayed.  
After the Enter Button is released, the alternate ‘interface’ will be selected and the setup  
information for the newly selected interface will be printed. (This is merely a shortcut method and  
accomplishes the same result as using the Interface Configuration Menu. This feature was added in  
printer firmware version 2.1.)  
RS-232C Serial Interface  
To communicate using the Serial interface, “Serial” must be selected in the Interface Menu as described on  
page 21. If there is no optional interface installed, Serial will be the only interface available. When using the  
Serial interface, the baud rate, data bits, parity, stop bit(s), and handshaking method (XON/XOFF, ETX/ACK,  
RTS/CTS) must be set to match the settings on the host computer. If these settings do not match, errors and/or

Interfacing to a Host Computer  
IrDA Interface  
In addition to the standard Serial interface, your MLP 3040 may be equipped with an optional IrDA interface.  
IrDA interfaces are commonly found on many PDA’s and notebook computers. To communicate using the  
IrDA interface, “IrDA” must be selected in the Interface Menu as described on page 23.  
The IrDA interface uses infrared light to provide a cable free, short range interface. Since the communications  
medium is light, it is “line-of-sight” and requires that the interfaces on the printer and the host device be aligned  
with, or pointed at, each other. The printer’s transmitter and receiver are located behind an “IrDA Window” as  
indicated in Figure 12.  
Whenever a host computer has established a connection with the printer, the  
illuminate.  
Wireless Indicator will  
Note: The printer’s IrDA implementation makes use of IrCOMM rather than IrLPT. As a result, some host  
systems will require that the printer connection be established using a “COM” port rather than  
selecting “IrDA”. In most PDA’s, for instance, this will be “COM3”.

Bluetooth® Interface  
In addition to the standard Serial interface, your MLP 3040 may be equipped with an optional Bluetooth  
interface. Bluetooth interfaces are built into some PDA’s and may be added to most others. Bluetooth  
interfaces may also be added to notebook or desktop computers. To communicate using the Bluetooth®  
interface, “Bluetooth” must be selected in the Interface Menu as described on page 24.  
The Bluetooth interface uses wireless, radio frequency signals to communicate, which eliminates the line-of-  
sight requirement imposed by the IrDA interface.  
The MLP 3040 Bluetooth interface acts as a “serial port adapter” operating as a “server”. Being a serial port  
adapter means, the printer may appear as a “Serial Device” when discovered, rather than as a “Printer”.  
Operating as a server, other devices such as a PDA or other host computer may initiate the connection to the  
printer.

Interfacing to a Host Computer  
When discovered, the default name that will appear will be “MLP 3040-aaannnnn” where “aaannnnn” is the  
printer’s serial number. To obtain the printer’s Bluetooth name, you may use the printer’s Setup menus or you  
may have the printer print it out. To print all the configuration for the interface, press and hold the Enter  
Button until “Printing Setup” is displayed.  
Whenever a host device has established a connection to the printer, the  
Wireless Indicator will be lit. When  
the host closes the connection, the indicator will turn off. To conserve battery power, application programs  
should disconnect from the printer whenever possible.  
Wi-Fi® Interface  
In addition to the standard RS-232C Serial interface, your MLP 3040 may be equipped with an optional Wi-Fi  
interface. Wi-Fi interfaces are built into some PDA’s and may be added to most others. Wi-Fi interfaces may  
also be added to notebook or desktop computers and as an “access point” to a wired network. To communicate  
using the Wi-Fi interface, “Wi-Fi” must be selected in the Interface Menu as described on page 26.  
The Wi-Fi interface uses wireless, radio frequency signals to communicate, which eliminates the line-of-sight  
requirement imposed by the optional IrDA interface.  
The MLP 3040 Wi-Fi interface acts as a server and will accept connections from a host device such as a PDA,  
notebook computer, or a network server.  
The MLP 3040 Wi-Fi interface conforms to the IEEE 802.11b standard. The factory default settings for this  
interface are:  
WLAN Type: Infrastructure  
WLAN SSID: any  
WLAN WEP Bits: 0 (Off)  
WLAN Auth: Auto  
IP Address Assign: DHCP (The DHCP name will be “MLP 3040-aaannnnn”  
where “aaannnnn” is the printer’s serial number.)  
Port: 8023  
These settings for the Wi-Fi interface features may be modified using the Interface Setup Menu as described  
beginning on page 26 with the exclusion of the IP Port. Note that changing the values of some of these features  
may cause additional features to be displayed. For instance, changing WLAN WEP Bits from “0”, or Off, to  
“64” or “128” will cause the “WEP Key 1-4” features to be displayed so that the appropriate sized encryption  
key(s) may be entered.  
To print out the current Wi-Fi configuration details, you may press and hold Enter Button until “Printing  
Setup” is displayed. This feature is especially useful for obtaining the current IP address when assigning  
addresses via DHCP. When doing so, be sure to wait several seconds after turning the printer on to allow it to  
establish a connection with the network and be served an address.  
The  
Wireless Indicator will light whenever the printer is currently receiving a print job.  
When operating in Infrastructure mode, the printer will attempt to conserve battery power whenever possible by  
placing the Wi-Fi interface into a low power mode when not communicating. However, according to the IEEE  
802.11b standard, the printer must be granted “permission” from the network’s Access Point before operating in  
the low power mode. Since different Access Point manufacturers implement this feature differently, the amount  
of power saving actually achieved varies. The actual power saving also varies with the amount of network  
traffic.

Power Considerations  
MLP 3040 printers are designed to provide superior output using as little power as necessary. This provides the  
longest possible battery life. The printers may also be operated from an external power supply when used in a  
more permanent installation in a vehicle or office. The following discussions indicate how the printer  
accomplishes this power conservation using features such as Standby and Auto Power Down. For more  
information on battery charging, please refer to “Charging the Battery” on page 40.  
Standby Operation  
When operating on battery power, the printer automatically enters a Standby mode one minute after last  
receiving data, printing, a front panel button is pressed, or a magnetic card reader swipe operation. When in  
Standby, the printer will flash the Power Indicator.  
While in Standby the printer turns off as many power consuming components as possible. However, the printer  
remains fully capable of receiving data or responding to a control panel button. The printer will automatically  
“wake up” when it begins to receive data from a host system, or when any front panel Button is pressed.  
Auto Power Down  
To conserve even more battery power, the printer may also be configured to turn itself off after a specified  
number of minutes of inactivity. When the printer powers down, this is equivalent to turning the printer off  
using the Power Button and the printer will no longer respond to incoming data.  
To enable the Auto Power Down feature, please refer to the Options Menu settings beginning on page 29.  
Operation Without A Battery  
MLP 3040 printers may be operated with an optional power supply and without a battery installed. Power  
supplies are available for use with 100-240VAC/50-60Hz and for 12/24VDC vehicle applications.  
Caution: Use only Psion Teklogix power supplies designed specifically for your MLP 3040 printer. Using a  
different power supply may cause damage to the printer and will not be covered by the printer’s  
warranty.  
Note: When the printer is connected to an external power supply, the printer will not enter Standby as  
described above.

Maintenance and Troubleshooting  
Cleaning  
In normal environments, the printer should be cleaned after printing a few rolls of paper or if there are voids in  
the printout. For optimum performance and life, you should clean the Print Head and Platen Roller whenever  
you load new paper. If your printer is an MLP 3040 SL model, you should also clean the Pick Roller.  
To clean the printer areas as described below, use a Thermal Head Cleaning Pen and MCR Cleaning Card  
available from Psion Teklogix, or you may use cotton swabs moistened with isopropyl alcohol. Please refer to

Battery Care  
Charging the Battery  
The printer’s battery is charged in the printer using an optional power supply. Power supplies are available for  
100-240VAC/50-60Hz and for 12/24VDC vehicle applications. Follow the steps listed below to charge the  
battery. An optional external two-bay charger is also available.  
Plug the power supply into a power source appropriate for the adapter being used.  
Plug the power supply into the power connector on the side of the printer. The printer’s battery  
charging circuitry will analyze the condition of the battery and begin charging it if necessary.  
If the battery is not fully charged, charging will begin and the Battery Indicator will illuminate.  
When the battery is fully charged, the Battery Indicator will turn off. Charging may take up to 2½  
hours depending on the condition of the battery.  
The printer may be used while the battery is charging, but this will extend the time required to fully  
charge the battery.  
The power supply may remain connected to the printer to keep the battery fully charged and will not  
cause damage to the printer or battery.  
The printer’s battery status is displayed in the lower right corner of the front panel LCD Display. The status is  
displayed as a battery shape which indicates the relative capacity that remains as indicated below.

Maintenance and Troubleshooting  
Testing the Power Supply and Battery  
To verify that the printer’s internal battery charger is functioning properly, perform the following steps.  
Test the power adapter (100-240VAC/50-60Hz, 12/24VDC adapter) with a voltmeter to verify that its  
output voltage is 9 VDC.  
Connect the power supply to a power source and then connect it to the printer.  
Verify that the printer’s Battery Indicator is illuminated. If illuminated, the charging circuit is  
functioning properly.  
Note: that if the battery is already fully charged, the Battery Indicator will turn off after a short  
time.  
After the battery has been charged for five minutes, disconnect the power supply.  
Perform a printer Self-Test.  
o
Make sure the printer is turned off. The power indicator will be off and the LCD Display will  
be blank.  
o
o
Press and hold the Paper Feed Button.  
Continue holding the Paper Feed Button and turn the printer on using the Power Button  
until “Printing Current Menu Values” is displayed.  
If the printer successfully prints the Self-Test, the battery is functional. If the Self-Test does not  
complete and the printer turns itself off, repeat this test with a known good battery.  
Once this test has completed successfully, allow the battery to fully charge. At the end of this time the  
Battery Indicator will turn off.  
Note: If the printer is turned on, the battery status shown in the bottom right corner of the LCD  
display will always show a “full” battery whenever the printer is connected to the power  
supply.  
If the printer and battery do not appear to successfully pass these tests, refer to the Troubleshooting section for  
possible causes and solutions.  
Note: This test only verifies that the power adapter, the internal charging circuit, and the battery are  
functioning properly. This test does not provide a valid indication of the relative capacity of the battery  
or how long it may hold a charge.
