Maintaining the Printer
c
Caution:
Read all caution and warning labels carefully, making sure to follow any instructions contained in
them. These labels are located on the inside of the printer’s covers and the interior of the printer
body.
Handle the printer with care to preserve its life. Abuse handling may cause damage and void your
warranty. If dust and paper scraps remain on the inside or outside of the printer, printer performance
and print quality will suffer, so the printer should be cleaned periodically. Keep the following
guidelines in mind.

Warning:
Turn off the printer, unplug the power cord, and disconnect all interface cables before cleaning. Do
not spill water or detergent into the printer; otherwise the printer will be damaged and an electric
shock may occur.
c
Caution:
The fuser unit is hot. When the right side cover is opened, the fuser unit temperature drops
gradually (40 minutes wait time).
❏
Be careful when cleaning the inside of the printer or removing media misfeeds, as the fuser unit
and other internal parts may be very hot.
❏
Do not place anything on top of the printer.
❏
Use a soft cloth to clean the printer.
❏
Never spray cleaning solutions directly on the printer’s surface; the spray could penetrate through
the air vents of the printer and damage the internal circuits.
❏
Avoid using abrasive or corrosive solutions or solutions that contain solvents (such as alcohol and
benzene) to clean the printer.
❏
Always test any cleaning solution (such as mild detergent) on a small inconspicuous area of your
printer to check the solution’s performance.
❏
Never use sharp or rough implements, such as wire or plastic cleaning pads.
