Lead edge image position adju Paper lead edge/rear edge void adjustment
(Outline)
This adjustment is used to adjust the copy image position and lead edge/rear edge void
amount on the copy paper by adjusting the image scan start position and the print start
position (resist roller ON timing) at 100%.
(Operation/Procedure)
1. When this simulation is executed, the currently set value is displayed in two digits.
(Center value: 50)
2. When the copy mode select key is pressed, each setting mode and the display are
changed.
* The selected adjustment mode is indicated by the lamps as shown in the table
below.
3. Enter the adjustment value with the 10-key and press the start key. The set value is
stored and a copy is made. (When the set value is increased by 1, the void amount is
shifted by 0.1 mm.)
4. When the clear key is pressed, the set value is stored and the simulation mode is
terminated.

(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.)
