Adjusting the Position of the
Photosensitive Drum Fixing
Shaft
Slide the photosensitive drum frame unit
about 5 cm out of the copier, and then slide it
back in. If the movement is not smooth, adjust
the position of the photosensitive drum fixing
shaft using the drum shaft positioning tool
(FY9-3045).
This adjustment, however, need not be
made if the images are free of color
displacement, blurring, and faults at intervals
and, moreover, the discrepancy between the
photosensitive drum fixing shaft and the hole
of the photosensitive drum flange is about 1
mm.
1) Slide out the photosensitive drum unit
from the copier.
2) Remove the six screws [1], and detach the
photosensitive drum butting blocks [2]
(front, back); then, detach the
photosensitive drum [3] from the
photosensitive drum frame unit [4].
3) Slide the photosensitive drum frame unit
into the copier, and secure it in place with
three screws.
4) Secure the drum motor assembly [5] to the
copier temporarily with seven screws [6].
