50 01 (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
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
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
The SPF adjustment is made by adjusting the SPF image scan start position immediately after turning on the
power.
10 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.

51 02 Resist quantity adjustment
Used to adjust the contact pressure of paper onto the copier resist roller.
(Operation/Procedure)
1. When this simulation is executed, the currently set value is displayed.
2. In a machine with the multi paper feed unit installed, press the copy mode select key, and each setting mode
and display are changed sequentially.
In a machine with the single paper feed unit installed, press the copy mode select key, and each setting
mode and display are changed sequentially.
∗ The selected adjustment mode is indicated by the lamps as follows:
3. Enter the adjustment value with the 10-key and press the SORT key. Then the set value is stored and a copy
is made.
4. Press the clear key to store the set value and exit the simulation.

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