12.2.3 DF Leading Edge Registration Adjustment
1. Using the DF test chart, make a copy in the platen cover mode (A4 width).
2. Confirm that the original select switch [A] is in the thin mode and again
using the test chart, make a copy in the DF mode (A4 width).
3. Compare the leading edge registration of both copies, and check that the
difference between the two copies is within 2.5 mm.
4. If the difference is more than 2.5 mm, remove the DF main PCB cover (1
screw) and adjust VR102 on the DF main PCB until the leading edge
registration is within specification.
NOTE: Turning VR102 clockwise results in stopping the original later.
5. Using the DF test chart, make a copy in the DF two sided-original mode.
(Insert the original face down.)
6. Compare the leading edge registration with that of the platen cover mode
copy, and check that the difference between the two copies is within 2.00
mm.
7. If out of specification, adjust VR103 on the DF main PCB until the
leading edge registration is correct.
NOTE: a) The test sheet stops pressed against the left scale in DF
two-sided original mode.
b) Turning VR103 clockwise results in the original stopping later.
