Interior Cleaning
291
To clean the interior of the printer perform the following steps.
1. Power off the printer and unplug the printer power cord.
2. Open the printer cover.
3. Fully raise the platen lever.
4. Unload the paper.
5. Remove the ribbon cartridge.
6. Lift the ribbon out of the ribbon path.
7. Brush the paper dust and ribbon lint off the tractors, shuttle cover
assembly, and base casting with a soft-bristled, non-metallic brush
(such as a toothbrush). Vacuum up the residue.
CAUTION
Vacuum carefully around the hammer bank and surrounding area to
avoid damage. To avoid corrosion damage, use only alcohol when
cleaning the printer mechanical elements. Solutions used to clean
mechanical elements must contain no water.
8. Wipe the splined shaft with a soft cloth.
9. Check the ribbon mask and hammer bank cover for bits of torn paper or
ribbon lint.
10. Remove dust and ink from the platen using a soft cloth lightly moistened
with anhydrous alcohol. (The platen is the thick silver bar behind the
hammer bank cover that rotates when the platen lever is rotated.)
CAUTION
When cleaning the platen, be very careful not to get any alcohol in the
hammer bank, because alcohol will cause severe damage to the
hammer bank. Only a trained service technician should clean the shuttle
assembly.
11. Brush and vacuum the accumulated dust or residue inside the lower
cabinet.
12. Wipe the lower cabinet interior with a clean, lint-free cloth dampened (not
wet) with water and mild detergent or window cleaning solution. Dry the
lower cabinet interior by wiping it down with a clean, lint-free cloth.
13. Install the ribbon and load paper.
