Original Registration Adjustment
1. Make a copy of the test sheet in the platen mode (A4 width).
2. Confirm that the original select switch is in the thin original mode and
make a copy in DF mode (A4 width).
3. Compare the registration of the copy in platen mode with that of the DF
mode, and confirm that the difference is within 2.5 mm.
4. If the difference is more than 2.5 mm, remove the DF main PCB cover [A]
(1 screw) and adjust VR102 to change the original-stop timing.
NOTE: Turning VR102 clockwise results in the original stopping later.
5. Make a copy of the test sheet in DF two-sided original mode.
NOTE: a) The test sheet should stop pressed against the left scale in DF
two-sided original mode.
b) The position of the original select switch does not matter.
6. Compare the registration of the copy in platen mode with that of DF
two-sided original mode, and confirm that the difference is within 2.0 mm.
7. If the difference is more than 2.0 mm, remove the DF main PCB cover
and adjust VR103 to change the original-stop timing.
NOTE: a) The test sheet should stop pressed against the left scale in DF
two-sided original mode.
b) Turning VR103 clockwise results in the original stopping later.
