Replacing the Backup Battery
When the backup battery is at its end of life, the printers date and time cannot 
be retained. Follow the procedure described below to replace the backup bat-
tery.
Note
Only use the coin-shaped 3V lithium battery CR2032. It’s very important 
to protect the printer controller board and any associated circuit boards 
from electrostatic damage. Before performing this procedure, review 
the antistatic caution on page 219. In addition, always handle circuit 
boards by the edges only.
1Turn off the printer and discon-
nect the power cord and inter-
face cables.

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 rear 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.

„Do not leave the printer’s covers open for any length of time, especially in 
well-lit places; light may damage the toner cartridges.
„Do not open the printer during printing.
„Do not tap media stacks on the printer.
„Do not lubricate or disassemble the printer.
„Do not tilt the printer.
„Do not touch the electrical contacts, gears, or laser devices. Doing so 
may damage the printer 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 printer may experience media misfeeds and excessive 
media curl.
„Make sure two people are avail-
able to lift the printer when mov-
ing it.
Keep the printer level to avoid 
toner spillage.
„When lifting up the printer, push 
the tray 1/2 completely into the 
printer and then lift the printer as 
shown in the right figure.
If an optional lower feeder 
unit is installed, remove it 
before lifting the printer.
„If you get toner on your skin, wash it off with cool water and a mild soap.
