Appendix A: Troubleshooting
The appendix tells you what you need to know 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, and on the meanings of
printer beep tones.
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
Use the following procedure to test the printer to make sure that everything is
working correctly.
❏ Turn off the printer.
❏ Make sure that paper is loaded in the printer.
❏ While holding down the control panel’s ON LINE button, turn the printer
back on.
This test continually prints the version number of the software contained in
the printer’s ROM, the current EDS settings, and the current Dot
Adjustment settings, followed by the entire character set printed in each font
and pitch available.
❏ To stop demo printing, turn the printer off.
Note:
The test prints across the entire width of the carriage. Make sure that the
printer is loaded with the widest possible paper available in order to avoid
damage to the print head and platen.
