3) Check the sub scanning direction distortion.
If La = Lb, there is no distortion.
If there is any distortion in the sub scanning direction, perform the
following procedures.
4) Loosen either one of the two fixing screws of the scanner unit
drive pulley.
5) Without moving the scanner unit drive shaft, manually turn the
scanner unit drive pulley to adjust the parallelism of the scanner
unit A. (Change the relative positions of the scanner unit drive
pulley and the drive shaft.)
6) Tighten the scanner unit drive pulley fixing screw.
Repeat procedures 2)
