COPY IMAGE ADJUSTMENT

6.2 COPY IMAGE ADJUSTMENT

6.2.1 LEADING EDGE REGISTRATION ADJUSTMENT

PURPOSE: To adjust the leading edge registration on prints in platen mode and
ADF mode.
ADJUSTMENT STANDARD:
Within 0 ± 2.0 mm (in platen mode)
Within 0 ± 2.5 mm (in ADF mode)
CAUTION: This adjustment is required every time the MPU has been replaced.
1. Turn on the main switch, and make a copy in platen mode.
NOTE: The image position on the trial print that is automatically made after
making a master tends to be inconstant. Do not use the trial print to
check the copy image.
2. Measure the difference between the leading edge registration of the original
and the print. If the registration does not meet specifications, go to the next
step.
3. Access SP26 (Feed Timing Adjustment).
4. Adjust the gap.
5. Exit the SP mode and make a copy.
6. Re-measure the leading edge registration to ensure it is within specifications. If
the registration meets specifications, go to the next step.
7. Make a copy in ADF mode and repeat the same steps using SP38 (ADF Scan
Line Adjustment). The specification in ADF mode is 0 ± 2.5 mm.
NOTE: SP38 changes the scanning start timing in the ADF mode, changing
the leading edge registration in the ADF mode.
