Testing the printer 47
Appendix A: 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.
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 of the printer.
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.
