(Adjustment method)

1.

Set the print start position (A: AE ON), the lead edge void amount (B: TEXT ON), the scanning start position
(C: PHOTO ON) to zero and make a copy of a scale at 100%.

2.

Measure the image loss R (mm) of the scale.
Set as C = 10 

× R (mm). (Example: Set to 30.)

∗ When C is increased by 10, the image loss is decreased

by 1 mm. (Default: 5)

3.

Measure the distance H (mm) from the paper lead edge to
the image print start position.
Set as A = 10 

× R (mm). (Example: Set to 50.)

∗ When the value of A is increased by 10, the image lead

edge is shifted toward the paper lead edge by 1 mm.
(Default: 50)

4.

Set the lead edge void amount as B = 50 (2.5 mm).
(Default: 50)

∗ When the value of B is increased by 10, the void is

increased by about 1 mm.
(For 25 or less, however, the void amount becomes zero.)

✩ The SPF adjustment is made by adjusting the SPF image scan start position immediately after turning on the

power.

Paper center offset + OC/Document center offset + SPF document center offset
(Outline)
The center offset position of copy image on the copy paper and that of document scan are adjusted by
adjusting the scan left margin of ASIC and the print left margin register set value.
(Operation/Procedure)

1.

When this simulation is executed, the currently set value is displayed.

2.

For a machine with a multi manual paper feed unit installed, when the copy mode select key is pressed, each
set mode and display are changed.
For a machine with a single manual paper feed unit installed, when the copy mode select key is pressed,
each set mode and display are changed.
