Interior Cleaning

Over time, particles of paper, ink, and ribbon accumulate inside impact
printers. This is normal. These particles must be removed periodically to avoid
degraded print quality. Most paper particles accumulate around the ends of
the platen and ribbon path.
To clean the interior of the printer, refer to Figure 12 and 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

hammer bank, because alcohol will cause severe damage to the
hammer bank. Only a trained service technician should clean the shuttle
assembly.
