Maintenance; Cleaning - Citizen 120D+ User Manual

APPENDIX A
MAINTENANCE
The Citizen 120D + printer requires very little routine
maintenance. In fact, the best maintenance for your
120D + printer is preventive. If you follow the suggestions
in Chapter 1 for locating the 120D + in an area free of
excessive dust and heat when you set up your printer, your
120D+ will give you long and trouble-free performance.
Periodic cleaning, replacement of the ribbon, and, after a
very long time, replacement of the print head are about the
only maintenance tasks you will encounter. We'll cover
these items in this chapter.
WARNING:
Always turn the power off, unplug the power
cord and disconnect the printer cable when performing any
type of maintenance.
CLEANING
Dirt and dust are the 120D + 's biggest enemies. The printer
cover will keep most dirt from the printer mechanism, but
an occasional cleaning to remove paper particles is a good
idea.
If you're just giving the 120D + a general cleaning, you
don't have to remove the upper case. First, turn the power
off and disconnect the power cord. Then just remove the
printer cover and the ribbon cartridge and clean the areas
you can easily reach, following the cleaning suggestions in
this section. When you have finished, replace the ribbon
cartridge and printer cover and reconnect the power cord.
To clean the inside of the printer completely, we
recommend that the printer is returned to a Citizen
authorised service agency.
Please note that any unauthorised dismantling of the
printer other than as previously defined for cleaning or
dipswitch setting will invalidate the Citizen warranty.
To clean the inside of the printer, use a soft brush to whisk
lint and dust away from the print head area, being careful
not to damage any of the cables and pulleys. Do not dust
the interface pack circuit board area.
The outside of the printer case can be cleaned when
needed with a damp rag and alcohol.
