Cleaning Inside the Cabinet
Over time, particles of paper and ink accumulate inside impact printers. This
is normal. Paper dust and ink build–up must be removed periodically to
avoid degraded print quality. Most paper dust accumulates around the ends of
the platen and ribbon path. To clean the interior of the printer, refer to 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. Raise the forms thickness lever.
4. Unlatch both ribbon spools and carefully lift them off the hubs. Raise
the ribbon out of the ribbon path.
