Maintaining the Machine
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.
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.
CAUTION
The fuser unit is hot. When the right side cover 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 sol-
vents (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.
