56 MFP unit explanation ENWW
Drum unit
Composition
Mechanisms
The drum unit is an integral assembly
consisting of a drum, charging corona unit,
developing unit, cleaning/toner recycle unit,
PCL, and separation claws.
*1 Auxiliary separation
• To prevent paper jamming, three
separation claws are used to
separate paper from the drum
forcibly. These separation claws are
pressed against the drum or detached
from it by turning on/off the separation
claw solenoid (SD1).
• To prevent a specific part of
image-copied paper from being
stained and to prevent the drum from
being scratched, the swing
mechanism slides the separation
claws about 8 mm back and forth in
parallel with the drum surface.
