roller cleaning procedure.
Tray pickup roller
Two different type rollers mount on the shaft of the tray
pickup roller assembly. The soft and eccentric roller is
the tray pickup roller. The hard plastic roller is the

Caution:
The EP-L cartridge is not light proof.
Prolonged exposure (more than 5 minutes) to room
light can cause damage that will produce noticeable
image defects.
Print density adjuster
Moving the slider to the right produces darker
print density and increases toner consumption. See
