Cleaning the printer and accessories
To maintain high print quality and performance, use the following opportunities to thoroughly clean
the printer and the paper handling accessories:
every time you change the toner cartridge (run a few pages through)
after printing approximately 5,000 pages for C (cyan), M (magenta), and Y (yellow); and 8,000
pages for K (black)
whenever print quality problems occur
Clean the outside surfaces with a water-dampened cloth. Observe the warning and caution below.
WARNING! Before you begin these steps, turn the printer off and unplug all power cords to avoid shock hazard.
Be careful when cleaning around the fusing assembly area. It might be hot.
CAUTION To avoid permanent damage to the toner cartridge, do not use ammonia-based cleaners on or around
the printer.
Do not touch the transfer roller. Skin oils on the roller can reduce print quality. If toner gets on your
clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets toner into fabric.
Cleaning spilled toner
Defective toner cartridges can develop leaks. Also, after a paper jam has occurred, some toner
might remain on the rollers and guides inside the printer. The pages that print immediately after the
jam can pick up this toner.
CAUTION When cleaning the printer, do not touch the transfer roller with the damp cloth or with your fingers.
Vacuum specifications
Do not vacuum the printer or any spilled toner using a conventional vacuum. Toner particles used in
this product might be too fine for effective vacuuming and could result in damage to conventional
vacuums.
A vacuum specifically designed for cleaning toner can be used if it is capable of filtering fine
particles (5 microns in diameter).
