2 Preventive Maintenance
Cleaning the Printer
The printer is designed to require very little maintenance. Aside from normal
replenishment of paper and ribbons, the only preventive maintenance
required is periodic cleaning.
Because operating conditions vary widely, the user must determine how often
to clean the printer.
Since there is no guarantee that the user will clean the printer regularly, you
should clean the printer whenever you are called to service it. The cleaning
procedures in this chapter pertain to all models.
WARNING Always disconnect the AC power cord before cleaning the printer.
CAUTION Do not use abrasive cleaners, particularly on the window.
Do not drip water into the printer. Damage to the equipment will result.
Do not spray directly onto the printer when using spray solutions. Spray
the cloth, then apply the dampened cloth to the printer.
Do not vacuum the circuit boards.
Cleaning the Outside Surfaces
1. Power off the printer.
2. Disconnect the AC power cord from the printer or the power source.
3. Remove paper and the ribbon.
4. Dampen a clean, lint-free cloth with water and a mild detergent or with
window cleaning solution. The cloth must be damp, not wet. Wipe down
the outside surfaces of the printer.
5. Dry the outside surfaces with a clean, lint-free cloth.
6. Open the printer cover.
7. Using a soft-bristled, non-metallic brush (such as a toothbrush), brush
paper dust and ribbon lint off the tractors, shuttle cover assembly, base
casting, and ribbon guides. Vacuum up the residue. (See Figure 5.)
8. Wipe the splined shaft with a soft cloth.
CAUTION To avoid corrosion damage, use only alcohol when cleaning printer
mechanical elements, and make sure the cleaning solution contains no
water.
