Cleaning Requirements
Cleaning Inside The Printer
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 66 (cabinet models) or
Figure 67 (pedestal models) and perform the following steps:
1. Power off the printer and unplug the printer power cord.
2. Unload the paper (explained in the Operator’s Guide).
3. Unlatch both ribbon spools and carefully lift them off the hubs. Raise the
ribbon out of the ribbon path.
4. Using a soft-bristled non-metallic brush, remove paper, ribbon, and dust
particles from the paper path, ribbon guides, and ribbon path.
5. Brush and vacuum accumulated paper, ribbon, and dust particles,
especially in the tractor, hammer bank, and base pan areas.
6. Cabinet models: Brush and vacuum up dust or residue that has
accumulated inside the lower cabinet.
7. Cabinet models: Wipe the lower cabinet interior with a clean, lint-free
cloth dampened with water and mild detergent. Dry the lower cabinet
interior by wiping it with a clean, dry, lint-free cloth.
8. Install the ribbon (page 47), load the paper (page 50), and set the top-of-
form (page 61).
