4) Perform the image lead edge reference position adjustment.
Shift to the copy mode, and make a copy at each of 100% and
200% in the document table mode.
When the adjustment value of RRCA is proper, the lead edge
image from 4.0mm is not copied in either of 100% and 200%
copy scale.
If not, change and adjust the RRCA value.
(Adjust so that the lead edge image from 4.0mm is not copied
in either of different copy magnification ratios.)
Repeat the above procedures until a satisfactory result is
obtained.
