Drum Pawls; Drum Toner Seals - Gestetner B003 Service Manual

PHOTOCONDUCTOR UNIT (PCU)
6.7.2 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).

6.7.3 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.

6.7.4 DRUM TONER SEALS

Seals have been added to the structure
of the PCU (photoconductor unit) to
further prevent toner leakage.
