4-2 Printer Maintenance
Cleaning the Printer and Accessories
To maintain high print quality and performance, thoroughly clean the
printer and the paper handling accessories:
Every time you change the Toner Cartridge (run a cleaning page).
After printing approximately 10,000 pages.
Whenever print quality problems occur.
Clean the outside surfaces with a lightly water-dampened cloth. Clean
the inside parts as indicated in Table 4-1. 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 may 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.
