If your printout has colored spots at 3.7 in.
(94 mm) intervals, follow the steps below to
solve the problem.
a
Turn off the machine’s power switch.
Disconnect all cables, and then unplug
the power cord from the AC power
outlet.
b
Fully open the top cover by lifting up on
the handle (1).
IMPORTANT
When the scanner is open, you cannot
open the top cover.
c
See the print sample to identify the color
causing the problem. The color of the
spots is the color of the drum you should
clean. For example, if the spots are
cyan, you should clean the drum for
cyan. Take out the drum unit and toner
cartridge assembly of the color causing
the problem.
IMPORTANT
• We recommend that you place the drum
unit and toner cartridge assembly on a
clean, flat surface with a sheet of
disposable paper or cloth underneath it in
case you accidentally spill or scatter toner.
• To prevent damage to the machine from
static electricity, DO NOT touch the
electrodes shown in the illustration.
