6. Troubleshooting
The appendix will provide help 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.
Short test
Use the following procedure to test the printer to make sure that
everything is working correctly.
1. Make sure that paper is loaded in the printer.
2. Turn off the printer.
3. While holding down the control panel’s ON LINE button, turn the
printer back on.
4. The short self-test prints the following information.
1) The version number of the software contained in the printer’s ROM.
2) All EDS settings.
If there is no paper at power on, self-printing starts after the paper is
loaded by the panel. In self-printing, only paper end detection is
available. All panel functions are ignored. After self-printing finishes,
the printer will reset.
