Appendix A: Troubleshooting
This appendix will help you if you experience problems with your printer. It
tells you how to test the printer, how to check system software settings, and how
to adjust the vertical alignment. In addition, there is information on actions to
take for specific problems.
Warning!
The printer uses high voltage. Do not attempt any other repair or maintenance
except as expressly recommended in this appendix. Unauthorized repair and
maintenance not only exposes you to the danger of electrical shock, it also may
damage your printer and void your warranty.
Testing the printer
There are two different tests you can use: a self test and a hexadecimal dump.
Self test
Make sure that paper is loaded in the printer.
Turn the printer off.
While holding down the control panel's ON LINE button or LINE FEED
button, turn the printer on.
To stop demo printing, turn the printer off.
Note:
The self test prints across the entire width of the carriage. Make sure that
the printer is loaded with the widest paper available in order to avoid
damage to the print head and platen.
Since this test can generate many lines of text and graphics, it is a good idea
to perform this test only when using continuous fanfold paper rather than
single sheets.
