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.
