Df Leading Edge Registration Adjustment (Ft6750) - Ricoh DF56 Service Manual

DF LEADING EDGE REGISTRATION ADJUSTMENT (FT6750)

1. Using the DF test chart, make a copy in platen cover mode (A4/LT width).
2. Confirm that the original select switch [A] is in thin mode, then make an-
other copy of the test chart in DF mode (A4/LT width).
3. Compare the leading edge registration of both copies. There should be
no more than a 2.5 mm difference.
4. If the difference is more than 2.5mm, remove the DF main PCB cover [B]
(1 screw) and turn VR102 on the DF main PCB unit until the leading edge
registration is within the specification.
NOTE: Turning VR102 clockwise results in the original stopping later.
5. Make a copy of the DF test chart in DF two sided-original mode. (Insert
the original face down.)
6. Compare the leading edge registration with that of the platen cover mode
copy. There should be no more than a 2.00 mm difference.
7. If the leading edge registration is out of specification, turn VR103 on the
DF main PCB until the leading edge registration is correct.
NOTE: a) The test sheet stops against the left scale in DF two-sided original
mode.
b) Turning VR103 clockwise results in the original stopping later.
