Cleaning Requirements
Clean the printer every six months or after every 1000 hours of operation,
whichever occurs first. If the printer is located in a dusty area or is used for heavy
duty printing, clean it more often.
Disconnect the power source before cleaning the printer.

WARNING
Exterior Cleaning
Clean the outside of the cabinet with a soft, lint–free cloth and mild detergent
soap. (Dishwashing liquid works well.) Do not use abrasive powders or chemical
solvents. Clean the windows with plain water or mild window cleaner
. Always
apply the cleaning solution to the cloth; never pour cleaning solution directly onto
the printer.
Interior Cleaning
Over time, particles of paper and ink accumulate inside impact printers. This is
normal. Paper dust and ink build–up must be periodically removed 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 perform the following steps.
1. Power off the printer and unplug the printer power cord.
2. Open the printer cover. Fully raise the forms thickness lever. Unload paper.
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 (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.
