Step 1
CIS detects the right edge of paper and the paper center position is estimated from the
detected point and the paper size, and then, difference degree from the center reference
point is calculated.
Timing: When the leading edge of paper is 0 mm – approx. 5 mm behind from the registration
roller.

MEMO :
Since CIS cannot detect the edge of transparency, shift degree should be specified
manually. It can be set up from the following service mode: COPIER > ADJUST >
FEED-ADJ > SFT-OHP.

Step 2
The registration roller shifts according to the difference degree from the center point
calculated in step1.
The paper continues to be fed and shifted by the registration roller.
Timing: When the leading edge of paper is 0 mm – approx. 70 mm ahead from the post-
registration sensor.

MEMO :
For the countermeasure against the paper edge on the fixing assembly, the roller shifts
per 0.5 mm in 7 steps (default) for each image. Moreover, image write start position is
also changed so there is no side-registration displacement.
The level of step can be changed from the following service mode: COPIER > ADJUST
> FEED-ADJ > REG-SLID.
