6.5.2 DRIVE MECHANISM
The drive from the main motor [A] is
transmitted to the drum [B] through a
series of gears, a timing belt [C], and
the drum drive shaft [D].
The main motor has a drive
controller, which outputs a motor lock
signal when the rotation speed is out
of the specified range. The flywheel
[E] on the end of the drum drive shaft
stabilizes the rotation speed (this
prevents banding and jitter on
copies).
6.5.3 DRUM PAWLS
The pick-off pawls [A], mounted in
the holders [B] on the drum and in
contact with the drum, strip paper
from the drum if it has not yet
separated. The gears [C] are
removable, and the positions of the
holders can be adjusted.
6.5.4 DRUM TONER SEALS
Seals have been added to the
structure of the PCU (photoconductor
unit) to further prevent toner leakage.
