5.2.4.2 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

5.2.4.1 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)
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 after entering the simulation
mode, the first sheet after turning off/on the
power, or the first sheet after inserting the
cassette. Use the second or later sheet to
check the rear edge void.
5.2.4.3 Center offset adjustment
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.
