50 01 Lead edge image position
(LEAD EDGE)
[Function]
Used to adjust the copy image position and the lead edge void amount on copy paper. The adjust-
ment is made by adjusting the image scan start position at 100% and the print start position (resist
roller ON timing). When this test command is executed, the current set value is displayed in 2 digits.
(Center value: 50)
When [ / ] key is pressed, the setting mode and the display are changed.
Enter the adjustment value and press [START] key to save the set value and make a copy.
When the adjustment is made by the main cassette paper feed, the adjustment values of all the paper
feed ports become the same. (When the set value is increased by 1, shift is made by 0.1mm.)

[Adjustment procedure]
1) Set the print start position (A: COPY mode lamp ON), the lead edge void amount (B: PRINT mode
lamp ON), the scan start position (C: SCAN mode lamp) to zero, and make a copy of the scale at
100%.
2) Measure the image loss (Rmm) of the scale.
Set C = 10 x R (mm). (Example: Set to 40.)
When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
3) Measure the distance (Hmm) from the paper lead edge to the image print start position.
Set A = 10 x H (mm). (Example: Set to 50.)
When the value of A is increased by 10, the image lead edge is moved 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 of B is increased by 10, the void is extended by about 0.1mm. (For 25 or less,
however, the void amount is regarded as 0.)
The SFP adjustment is made by adjusting the SPF image scan start position after OC adjustment.

When paper is discharged, the shifter is operated.
