adjustment
1) Loosen the screw which is fixing the scanner unit A and the drive
wire, and remove the scanner unit A from the drive wire.
2) Manually turn the scanner drive gear to bring the scanner unit B
into contact with the stopper.
At that time, if the scanner unit B makes contact with the two stop-
pers on the front and the rear frame simultaneously, the parallel-
ism of the scanner unit B is proper.
If not, perform the following procedures.
3) Loosen the fixing screw of the scanner unit drive pulley on the
side where the scanner unit B is not in contact with the stopper.
4) While keeping the scanner unit drive shaft stationary, turn the
scanner unit drive pulley manually so that the scanner unit B
makes contacts with two stoppers on the front and the rear frame
side simultaneously. (Change the relative positions of the scanner
unit drive pulley and the drive shaft.)
5) Fix the scanner unit drive pulley fixing screw which was loosened
in procedure 3).
6) Perform procedure 2).
Repeat procedures 3) – 6) until the parallelism of the scanner unit
B becomes proper.
7) With the scanner unit B in contact with two stoppers on the front
and the rear frame side simultaneously, slide the scanner unit A
until it comes to the right end of the frame, and fix it to the drive
wire with the fixing screw.
