• Make sure the power cord is properly plugged into a
power outlet.
• Connect another electrical appliance to the outlet to
see if it has power.
• If a beep sound is not made when you press the keys,
unplug the power cord, wait at least 5 seconds, and
then plug it in again.
• Check the size and weight of the document (see page
55).
• The toner cartridge may need replacement (see page
150).

and wipe the surface of the drum (the green cylinder)
with a dry cotton swab. If print quality does not
improve after wiping with a dry cotton swab, you can
try moistening the swab with isopropyl alcohol or
ethanol. However, do not moisten the swab with
isopropyl alcohol or ethanol unless absolutely
necessary, as this may cause stains or smears to
appear on the first pages printed after cleaning (the
stains may never completely disappear).
