CHAPTER 7 PICK-UP/FEEDING SYSTEM
c. Adjusting the Horizontal Registration (service mode)
If displacement occurs in the rear/front direction when picking up the second side of an
overlay/double-sided copy, adjust the horizontal registration in service mode (ADJUST>FEED-
ADJ>ADJ-REFE).
In this mode, the position of the horizontal registration sensor is moved virtually in memory to
move the point of laser exposure. It is not to move the sensor position mechanically.
• If the image is displaced toward the rear, decrease the setting.
Figure 7-135
• If the image is displaced to the front, increase the setting.
