Perpendicularity Adjustment
Adjust image skewing (squareness) in 0.1 mm increments for both sides 1 and 2.
Specify a positive value to adjust the position of the image in the opposite direction of
the paper feed direction, and a negative value to adjust the image in the paper feed
direction.
1 Check the sample printout, measuring the amount of squareness misalignment.
Use the following equation to obtain the perpendicularity misalignment amount, with
"A" as the length of the lead registration at the rear of the machine, and "B" as the
length of the lead registration at the front of the machine.
Perpendicularity misalignment amount =(A - B) × 400 ÷ (length of Y direction of paper
- 20 mm)
For example, when A3 is placed horizontally:
(A - B) × 400 ÷ 277
2 Select [Perpendicularity], and then select
[Change Settings].
3 Enter a value by adding the perpendicularity
misalignment amount measured in step 1 to
the current setting value of [Side 1] and [Side
2].
Note • The values displayed in [Side 1] and [Side
2] vary depending on the machine. The
Alignment Adjustment Type feature
adjusts relative difference between the
sides 1 and 2. Thus, if adjustable amount
to the desired direction is not enough in one side, adjust the other side.
