(1) Lead edge adjustment
1) Set a scale to the center of the paper lead edge guide as
shown below, and cover it with B4 or 8-1/2" x 14" paper.
2) Execute SIM 50-01
3) Set the print start position (AE lamp ON) (A), the lead edge
void amount (TEXT lamp ON) (B), and the scan start position
(PHOTO lamp ON) (C) to 0, and make a copy of a scale at
100%.
4) Measure the image loss amount (R mm) of the scale image.
Set C = 10 X R (mm). (Example: Set the value of C to 30.)
When the value of C is increased by 10, the image loss is
decreased by 1mm. (Default: 50)
5) Measure the distance (H mm) between the paper lead edge
and the image print start position.
Set A = 10 X H (mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead edge
is shifted to the paper lead edge by 1mm. (Default: 50)
6) Set the lead edge void amount to B = 50 (2.5mm).
When the value of B is increased by 10, the void amount is
increased by about 1mm. For 25 or less, however, the void
amount becomes zero. (Default: 50)

(2) Image rear edge void amount adjustment
1) Set a scale to the rear edge section of A4 or 11" x 8-1/2" paper
size as shown in the figure below, and cover it with B4 or 8-1/
2" x 14" paper.
2) Execute SIM 50-01 to select the image rear edge void amount
adjustment mode.
The set adjustment value is displayed on the copy quantity dis-
play.
3) Make a copy and measure the void amount of image rear
edge.
4) If the measurement value is out of the specified range, change
the set value and repeat the adjustment procedure.
The default value is 50.
Note: The rear edge void cannot be checked with the first sheet
(3) Center offset adjustment
Image loss:
R = 3mm
1) Set the self-made test chart for the center position adjustment
so that its center line is aligned with the center mark of the
document guide.
• Test chart for the center position adjustment.
Draw a line at the center of A4 or 8-1/2" x 11" paper in the paper
transport direction.
2) Execute SIM 50-10 to select the print center offset (cassette
paper feed) adjustment mode.
The set adjustment value is displayed on the copy quantity dis-
play.
