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.

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.
