Appendix A
Maintenance and Fault Finding
Introduction
Your printer requires very little routine maintenance. In fact, the best maintenance for the printer is
preventative. If you have followed the suggestions for locating it in an area free of excessive dust
and heat it will give you a long and trouble-free performance.
Periodic cleaning, replacement of the ribbon, replacement of an occasional blown fuse and, after
a very long time, replacement of the print head are about the only maintenance tasks you’ll need
to carry out. We’ll cover these items in this chapter. However, before carrying out any of these
tasks make sure that the printer has been switched off.
Cleaning dirt and dust are the biggest enemies. The print head cover will keep most dirt from the
printer mechanism, but occasional cleaning to remove paper particles is a good idea.

Cleaning the Carriage Shaft
The carriage shaft is coated with oil, which attracts dust, etc. wipe solid parts with a soft cloth to
clean them.
NOTE
When cleaning, be careful not to scratch the equipment or to bend parts, etc.
