6 Routine Service and
Diagnostics
Cleaning Requirements
Periodic cleaning is the only routine maintenance your printer requires to
ensure efficient operation and clear print quality.
If print quality deteriorates even after cleaning, contact your authorized
customer service engineer.
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.
WARNING
Disconnect the power source before cleaning the printer.
WARNUNG

ATTENTION
Débranchez l'alimentation avant de nettoyer l'imprimante.
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, refer to Figure 46 and perform the following
steps.
1. Power off the printer power and unplug the printer power cord.
2. Open the printer cover. Fully raise the forms thickness lever. Unload
paper. Refer to the Operator’s Guide.
