50 01 Lead edge image position
Used to adjust the copy image position and the lead edge void amount on the copy paper. The adjustment is made by
adjusting the image scan start position and the print start position (resist roller ON timing) at 100%.
(Operating procedure)
When this simulation is executed, the current setup value is displayed the current setup value is displayed in two digits.
(Center value: 50) Press the exposure select key to select your desired copy mode, and the display will change. Enter the
adjustment value and press the START key, and the setup value will be saved and a copy will be made. Press the clear key to
save the setup value and exit from the simulation mode. When the adjustment is made for the main cassette feed, all the
adjustment values at all the paper feed ports become the same. (Increasing the setup value by 1 corresponds to about 0.1mm
shift.)

: Supported if the model is installed and skipped if it is not installed.
(Adjustment procedure)
1. Set the print start position (A), the lead edge void amount (B) and the scan start position (C) to 1 (Set range: 1 – 99), and
make a copy at 100%.
2. Measure the image loss amount (R mm) of the scale.
Set C = 10 × R (mm) (Example: Set 40.)
When the value C is increased by 10, the image loss is decreased by 1mm.
(Default: 50)
3. Measure the distance (H mm) from the paper lead edge to the image print
start position.
Set A = 10 × H (mm) (Example: set 50)
When the value A is increased by 1mm, the image lead edge is shifted to
the paper lead edge by 1mm. (Default: 50)
4. Set the lead edge void amount to B = 50 (2.5mm). (Default: 50)
When the value B is increased by 10, the void is increased by about 1mm.
(When set to 25 or less, the void becomes zero.)
• The ADF adjustment is performed by adjusting the ADF image scan start position.
06 Copy lead edge position adjustment (ADF) <ADF model only>
The ADF copy lead edge adjustment is performed.
When the document scan position adjustment value is increased by 1, the scan start timing is advanced by 0.1mm.
As the print result, it is shifted in the direction opposite to the scan start position.
Each mode can be selected by pressing the exposure select key.

Rear edge void amount (ADF)
∗ When there is no document in the ADF, copy is inhibited.
10 Center offset adjustment
Used to adjust the copy image position on the copy paper and the center offset position when scanning a document.
(Operating procedure)
When this simulation is executed, the current setup value is displayed. Enter the adjustment value and press the START key,
and the entered value will be saved and a copy will be made. When the clear key is pressed, the entered value will be saved
and the simulation will be terminated. (When the setup value is increased by 1, shift is increased by 0.1mm.)
The exposure select key is used to select the mode.

Second side center offset (Main cassette paper feed)
: Supported only for installing models, and skipped for not-installing models.
∗ When the setup value is too great, outside of the shading area may be read, and black streaks may be produced on the
edges.
When the adjustment value is increased, the image is shifted to the left.
When the adjustment value is decreased, the image is shifted to the right.
