5) Make a copy of the test sheet in DF two-sided original mode.
NOTE: 1. The test sheet must be set facedown.
2. The original select switch can be set at any position.
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: 1. The test sheet should stop pressed against the left scale in DF
two-sided original mode.
2. Turning VR103 clockwise results in the original stopping later.
23. Reassemble the copier. (The DF harness fits in the cut-out on the rear
cover as shown.)
24. Check the operation of the DF.
25. Position the original select switch to thin original mode (normal position)
and explain the function of this switch to the customer.
