Maintaining the Printer
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.
CAUTION
The fuser unit is hot. When the top cover is opened, the fuser 
unit temperature drops gradually (one hour wait time).
#Be careful when cleaning the inside of the printer or removing media mis-
feeds, 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 inter-
nal circuits.
#Avoid using abrasive or corrosive solutions or solutions that contain sol-
vents (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.
#Always close the printer’s covers gently. Never subject the printer to vibra-
tion.
#Do not cover the printer immediately after using it. Turn it off and wait until 
it cools down.
