To maintain the print quality, follow the cleaning procedures below, each time the toner cartridge is replaced
or if print quality problems occur.
NOTE: Do not touch the transfer roller located under the toner cartridge when cleaning inside the
printer. Oil from your fingers may cause print quality problems.
CAUTION: Cleaning solvents that contain alcohol or other strong substances may discolor
or crack the printer cabinet.
Cleaning the Exterior
Clean the printer cabinet with a soft, damp, lint-free cloth. Do not let water drip onto the printer or inside
the printer.
Cleaning the Interior
Paper, toner, and dust particles can accumulate inside the printer and cause print quality problems, such as
smearing or toner specks. Clean inside the printer to prevent these problems.
Power the printer off and unplug the power cord. Allow a reasonable amount of time for the printer to
cool down. 1.
Open the front cover and pull the toner cartridge straight out. Set it on a clean flat surface. 2.
CAUTION: To prevent damage, do not expose the toner cartridge to light for more
than a few minutes.
CAUTION: Do not touch the green underside of the toner cartridge. Use the handle on
the cartridge to avoid touching this area.
With a dry and lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and
the toner cartridge cavity. 3.
