CHAPTER 2 STANDARDS AND ADJUSTMENTS
10) Without pulling the transfer drum sheet,
lightly press along the middle of the
double-sided tape, along the trailing edge
of the sheet in sequence: [1], [2], and [3].
11) Move the thumbs in axial direction,
lightly pressing against the linking plate
so that the double-sided tape will be
firmly in contact.
12) Shift back the lever released in step 1).
13) Check the transfer drum sheet for
scratches, dents, and slack.
Caution:
Be sure there is no distortion or slack in
the middle of the transfer drum. If
distortion exists, the transfer drum will
likely come into contact with the
photosensitive drum, causing toner to
fuse to the photosensitive drum and
ultimately leading to cleaning faults of
the photosensitive drum; if slack exists,
on the other hand, such image faults as
transfer faults and color displacement
can occur.
14) Mount the transfer drum side scraper
removed when detaching the old transfer
drum sheet, and then mount the transfer
drum to the machine.
