CLEANING AND REPLACEMENT
CLEANING THE LASER UNIT
When the laser unit inside the machine becomes dirty, line patterns (coloured lines) may form
in the printed image. If line patterns (coloured lines) appear, clean the laser unit.
Identifying lines (coloured lines) caused by a dirty laser unit
Coloured lines always appear in the same place. (The lines are never black.)
Coloured lines appear in parallel with the direction of paper feeding.
Coloured lines appear not only on output from a copier but also on prints from a
computer. (The same lines appear on both copies and print jobs.)
