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 three different tests you can use: a short test, a long test and a hexadecimal dump.

Short test

❏Make sure that paper is loaded in the printer.

❏Turn the printer off.

❏While holding down the control panel’s ON LINE button, turn the printer on.

The short test prints the version number of the software contained in the printer’s ROM followed by the current EDS settings.

Note:

The short 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.
