6.2.2 SIDE-TO-SIDE REGISTRAION ADJUSTMENT

PURPOSE: To adjust the side-to-side image position on prints by changing the
main-scan positions in platen and ADF modes.
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 side-to-side edge registration of the
original and the print. If the registration does not meet specifications, go to the
next step.
3. Access SP31 (Scan Center Adjustment - Platen Mode).
4. Adjust the gap.
5. Exit the SP mode and make a copy.
6. Re-measure the side-to-side 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 SP37 (ADF Center
Adjustment - ADF Mode). The specification in ADF mode is 0 ± 2.5 mm.
