8.6.2 Checking Horizontal Registration

0007-2214
The machine does not have a mechanism to check horizontal registration for both 1st and
2nd sides of a print. The point of horizontal registration for the 2nd side may be adjusted in
service mode (i.e., the image write start position).
The degree of arching for registration on the 2nd side of a double-sided print must be
adjusted separately from the adjustment for the 1st side to accommodate the fact that
different feed paths are used up to the registration roller for 1st and 2nd sides.
Service Mode:
COPIER>ADJUST>FEED-ADJ>ADJ-REFE
Use it to adjust the horizontal registration for the 2nd side of small-size double-sided prints.
COPIER>ADJUST>FEED-ADJ>ADJ-RE-L
Use it to adjust the horizontal registration for the 2nd side of large-size double-sided prints.
COPIER>ADJUST>FEED-ADJ>LOOPREFE
Use it to adjust the degree of arching for the 2nd side of double-sided prints.
Reference:
small-size: A4, B5, and the like, whose side in paper feed direction is shorter than that of
LTR.
Large-size: A3, A4R, B5R, and the like, whose side in feed direction is longer than that of
LTR.
The term "2nd side of a double-sided print" as used in relation to the machine's service mode
refers to the side that receives an image second in order; in other words, it corresponds to
the 1st side of the original.
