3-2-1 Memory Switch setting for Star mode
• Settings
Memory Switches are from MSW 0 to MSW 8. They are stored in non-volatile memory (flash
memory). To change the settings, send the following commands from the host.
[Name] Set Memory Switch
[Code] ASCII ESC GS # m {n1 n2 n3 0n4}0 ... {n1 n2 n3 n4}

LF NUL
Hexadecimal 1B 1D 23 m {n1 n2 n3 0n4}0 ... {n1 n2 n3 n4}8 0A 00

[Function] Sends command to write after defining Memory Switch using the definition command specified by
the following classes to set the Memory Switch. The printer is automatically reset after writing the
setting defined by that command to the non-volatile memory.
Do not turn off the power to the printer while sending commands to the non volatile memory. Doing
so will destroy the Memory Switch setting. It is also possible for all Memory Switch settings to
become offset to their initial, default settings.
Consider the life of the non-volatile memory and avoid over-use of this command.

7. Self Test
The self test let you know if your printer is operating properly. It checks the printing quality,
ROM version, DIP Switch settings, memory switch settings and statistic data.
The test is independent of any other equipment or software, so it is a good idea to run it
when you first set up the printer or if you have any trouble. If the self test works correctly, the
problem is in the other equipment or the software, not the printer.
• Running the self test
1) Make sure the printer is turned off and the printer cover is closed properly.
2) Turn on the power while pressing the Feed button and release the button, then the paper
will feed. Self diagnostics will begin and printer settings will be printed. Paper will be cut
upon completion of the test and printing will stop. (ERROR lamp will be on.)
3) Press the FEED button to continue printing the statistic data.
4) Press the FEED button to continue printing the rolling ASCII pattern.
5) The self test mode terminates after printing the rolling ASCII pattern automatically.

8. Hexadecimal Dumping
• Hexadecimal dump
This feature allows experienced users to see exactly what data is coming to the printer.
This can be useful in finding software problems. When you turn on the hexadecimal dump
function, the printer prints all commands and other data in hexadecimal format along with a
guide section to help you find specific commands.
• To use the hexadecimal dump feature, follow these steps:
1) After you make sure that the printer is off, open the rear cover of the printer.
2) Hold down the FEED button while you turn on the printer.
3) Close the rear cover.
4) Run any software program that sends data to the printer. The printer prints "Hexadecimal
dump" and then all the codes are received in a two column format. The first column
contains the hexadecimal codes and the second column gives the ASCII characters that
correspond to the codes.

10. Appendix - Troubleshooting
This chapter gives solutions to some printer problems you may have.
10-1 ERROR LED blinking pattern
The printer stops all printer operations for the selected paper section, goes off line, and the
ERROR LED blinks when an error is detected.
• Errors that automatically recover
ERROR LED blinking pattern
Rear cover open error
(When recoverable
Error is selected)(*1)
The rear cover is opened
when printing
Recovers automatically
when the rear cover is
closed.
Print head
temperature error(*2)
The temperature of the
print head is extremely
high.
Recovers automatically
when the print head
cools.
(*1) These conditions are selected by MSW8-5, 8-8. When MSW8-5 (mapping of the cover
open status) is off, the error hasn’t occurred but there is a “paper end error” instead. If
MSW8-8 is off, this error is handled as an automatically recoverable error.
(*2) Print head temperature error is not abnormal.
• Recoverable errors
When a recoverable error occurs, after the cause of the error is removed, the printer can
recover from the error by receiving an error recovery command without turning off the power.

If you see this light blinking, turn off the printer for a few seconds and then turn it back on.
If the light is still blinking, call your supervisor or a service person.
10-2 The printer does not start printing
• Are any of the operation panel lights on, If no operation panel lights are on, check
the following:
- Make sure that the printer is turned on.
- Make sure that the power supply cable is correctly plugged into the printer and to the
power outlet.
• If any of the lights are on, please check the following:
- If the ERROR LED is on (but not blinking), the printer is off line. Check to see that the
covers are closed and check the paper state. See Chapter 5 for instructions on installing
or replacing the paper roll.
- If the ERROR LED is blinking, there is an error. In this case, turn off the printer for a few
seconds and then turn it back on. If the light is still blinking, call your supervisor or
service person.
- If the PAPER OUT LED is on, check the paper roll in the printer. See Chapter 5 for
instruction on installing the paper roll.

10-3 The printer stops printing
• If the ERROR LED is on (but not blinking), the printer is off line. Check to see that the
covers are closed and check the paper state. See Chapter 5 for instructions on installing or
replacing the paper roll.
• If the ERROR LED is blinking, there is an error. In this case, turn off the printer for a few
seconds and then turn it back on. If the LED is still blinking, call your supervisor or a
service person.
• Turn off the printer and check for a paper jam. To clear paper jam, follow the steps below:
1) Turn off the printer and open the rear cover of the printer.
2) Remove the jammed paper and reload the paper roll as described in Chapter 5.
3) Close the rear cover.
4) Turn on the printer.
10-4 You want to check the operation of the printer by itself
• Self test
Try to run the self test to check that the printer works properly. See the self test
instructions in Chapter 8 to run the self test. If the self test does not work, contact your
supervisor or a service person.
If the self test works properly, check the following:
1) Check the connection at both ends of the interface cable between the printer and the
computer. Also make sure that this cable meets the specifications for both the printer
and the computer.
2) The data transmission settings may be different between the printer and computer.
Make sure that the printer’s DIP Switch settings for data transmission are the same as
the computer’s. You can see the printer’s interface settings on your self test printout.
If the printer still does not print, contact your dealer or a qualified service person.
10-5 Printing is poor
Check the state of ribbon cassette. If the ribbon cassette life ends, replace the ribbon
cassette as described in Chapter 4.
If the printer is still poor, contact your dealer or a qualified service person.
