To use the printer safely
Caution
Use water or neutral detergents for cleaning. Cleaning with volatile liquids such as thinner or benzene
will damage the surface of the printer.
Do not use cleaning materials that contain ammonia. They will damage the printer and the toner
cartridge.
After you have just used the printer, some parts inside the printer will be extremely hot. When you
open the front or back cover of the printer, never touch the shaded parts shown in the illustrations
below.
There are high voltage electrodes inside the printer. Before you clean the printer, clear a paper jam
or replace parts, make sure you have turned off the power switch and unplugged the printer from
the AC power outlet.
Do not handle the plug with wet hands - it might give you an electrical shock.
