7.11 Cleaning the Printer
This section explains how to clean the printer to keep it in good condition and to ensure
optimum print quality.
CAUTION
• Be sure to switch off and unplug the machine before accessing the interior of the
machine for cleaning, maintenance, or fault clearance. Access to a live machine's
interior can cause electric shocks.
Cleaning the Exterior
Clean the exterior of the printer monthly or more often if needed. To clean the exterior
surfaces, wipe them with a soft, firmly wrung cloth moistened with water. Then, wipe off any
excess water with a soft dry cloth. If dirt or smudges do not come off easily, gently wipe them
off with a soft, firmly wrung cloth moistened with a small amount of neutral cleaner.
Important
• Do not spray cleaning agents directly on the printer. The fluid may seep through the cracks and cause
problems. Do not use cleaning agents other than neutral cleaners.
Cleaning the Interior
After clearing paper jams or replacing the toner cartridges or drum cartridge, check and
clean the interior of the printer before closing the cover.
CAUTION
• Never touch a labelled area found on or near the fuser unit. You can get burnt. If a sheet
of paper is wrapped around the heat roller, do not try to remove it by yourself to avoid
injuries or burns. Switch off the machine immediately, and contact our Customer Support
Center or your dealers.
• Check for and remove any scraps of paper stuck in the printer.
• If you see any dust or dirt, wipe it off with a soft dry cloth.
