3)
Set the items RRCA, LEAD, and SIDE to the default values.
4)
Perform the image lead edge reference position adjustment.
Press [CLOSE] key to shift from the simulation mode to the
copy mode. Make a copy at 100% and at 200% in the docu-
ment mode.
If the lead edge section from 3.0mm position of scale in the
copy images of both 100% and 200% is not copied, the adjust-
ment value of RRCA is proper.
If the above conditions are not satisfied, change the adjust-
ment value of RRCA to adjust.
(Adjust the adjustment value of RRCA so that the lead edge
section from 3.0mm position of scale is not copied for different
copy magnification ratios.)
Repeat the above procedures until a satisfactory result is
obtained.

This adjustment is used to adjust the scanner reading position
when scanning the front surface in the DSPF mode.
If this adjustment is improper, the scanner stop position is shifted to
the specified position, and a shade of the document table may be
copied in the lead edge section of the scan image in the DSPF
(front surface) mode.
(Note)
After completion of this adjustment, be sure to perform the “ADJ9C
copy mode image loss adjustment (DSPF mode)”.
(The value of "SIDE2" in Sim. 50-6 is adjusted.)
Make a copy of white paper in the DSPF (front surface) mode, and
check to confirm that no shade is printed in the lead edge section of
the copy image.
