(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.

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).
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.)
