Purpose
To correct the optical image skew in
the Drum axis and paper feed
directions.
NOTE
:
•
Ensure that the following are
functioning correctly:
1. Paper is fed properly.
a. There is no difference in skew level between
Trays.
b. There is no difference in skew level between
continuously-made copies.
2. The Regi-Guide(or Gate) and the Platen Glass
are positioned properly.
3. The Full-Rate/Half-Rate Carriages Parallel
Adjustment is properly performed. …...
(4.3.1)
4. There is no difference in skew level between
A4 & A3 ( or between B5 & B4).
* If there is some difference, check to see if
the bottom half of A3(or B4) paper skews due
to the uneven transporting force of the Fuser
owing to a defective P Roll. Replace the P
Roll if necessary.
* The Regi-Roll is deteriorated or worn out.
5. Do not adjust paper skew by this means.
6. After this adjustment, make sure to record in
the Machine History Card that it has been
performed.
