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

							❏Always close the machine’s covers gently. Never subject the machine to vibration.
❏Do not cover the machine immediately after using it. Turn it off and wait until it cools down.
❏Do not leave the machine’s covers open for any length of time, especially in well-lit places; light
may damage the toner cartridges.
❏Do not open the machine during printing.
❏Do not tap media stacks on the machine.
❏Do not lubricate or disassemble the machine.
❏Do not tilt the machine.
❏Do not touch the electrical contacts, gears, or laser devices. Doing so may damage the machine and
cause the print quality to deteriorate.
❏Keep media in the output tray at a minimum level. If the media is stocked too high, your machine
may experience media misfeeds and excessive media curl.
❏When lifting the machine, grasp the areas shown in the figure. 
Keep the machine level to avoid toner spillage.
❏Before moving the machine, remove the dust cover, and fold up Tray 1.
❏If the optional 500-sheet paper cassette unit, attachment and duplex option are installed, remove
them and move them separately.
❏If you get toner on your skin, wash it off with cool water and a mild soap.
c
Caution:
If you get toner in your eyes, wash it out immediately with cool water and consult a doctor.
❏Make sure any parts removed during cleaning are replaced before you plug in the machine.
