Troubleshooting

2.3 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
"Installing paper roll"(1.5) in
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 1.
3) Close the rear cover.
4) Turn on the printer.
Turn off the printer and check for a ribbon jam. To clear ribbon jam, follow the steps below:
1) Turn off the printer and open the front cover of the printer.
2) Remove the jammed ribbon and reinstall the ribbon cassette as described in Chapter 1.
3) Close the front cover.
4) Turn on the printer.

2.4 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 1
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.

2.5 Printing is poor

Check the state of ribbon cassette. If the ribbon cassette life ends, replace the ribbon cassette as
described in Chapter 1.
If the printer still is poor, contact your dealer or a qualified service person.

2.6 You want to check a software program

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 it receives 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.
Hexadecimal dump
1B 21 00 1B 26 02 40 40 . !
1B 25 01 1B 63 34 00 1B . % .
41 42 43 44 45 46 47 48 A B C D E F G H
(A period(.) is printed for each code that has no ASCII equivalent.)
5) When the printing finishes, turn off the printer.
