6) Measure the distance H between the paper lead edge and the image print start position. Set the image print start position set value again.

• 1 step of the set value corresponds to about 0.127mm shift.

• Calculate the set value from the formula below.

99 – H/0.127 (mm) = Image print start position set value <H: Print start position measurement value (mm)>

∗ Fit the print edge with the paper edge, and perform the lead

edge adjustment.

6) Execute the main scanning direction (FR) distortion balance adjustment previously described in 2) again.

(8) Main scanning direction (FR direction) distortion

balance adjustment (Rail height adjustment)

When there is no skew copy in the mirror base scanning direction and there is no horizontal error (right angle to the scanning direction), the adjustment can be made by adjusting the No. 2/3 mirror base unit rail height.

Before performing this adjustment, be sure to perform the horizontal image distortion adjustment in the laser scanner section.

This adjustment must be performed in the following cases:

• When the mirror base wire is replaced.

• When the copy lamp unit and no. 2/3 mirror unit are replaced.

• When the mirror unit rail is replaced and moved.

• When a following copy is made.

1) Make an original for the adjustment.

Make test sheet by drawing parallel lines at 10mm from the both ends of A3 (11" x 17") white paper as shown below. (These lines must be correctly parallel to each other.)

If the width (La) of the black background at the lead edge is equal that (Lb) at the rear edge, there is no need to execute the following procedures of 4) – 7).

4) Loosen the mirror base drive pulley fixing screw on the front frame side or on the rear frame side.

• When La < Lb Turn the mirror base drive pulley on the front frame side in the arrow direction A. (Do not move the mirror base drive pulley shaft.)

• When La > Lb Turn the mirror base drive pulley on the rear frame side in the arrow direction A. (Do not move the mirror base drive pulley shaft.)

5) Tighten the fixing screw of the mirror base drive pulley.

2) Make a normal (100%) copy of the test sheet on A3 (11" x 17") paper. (Fit the paper edge and the glass holding plate edge.)

3) Measure the distances (La, Lb, Lc, Ld) at the four corners as shown below.

When La = Lb and Lc = Ld, no need to perform the procedures 4) and 5).

AR-5726/5731 ADJUSTMENTS 5 - 6

4) Move the mirror base B rail position up and down (in the arrow direction) to adjust.

• When La > Lb Shift the mirror base B rail upward by the half of the difference of La–Lb.

• When La < Lb Shift the mirror base B rail downward by the half of the difference of Lb–La.

Example: When La = 12mm and Lb = 9mm, shift the mirror base

B rail upward by 1.5mm.

• When Lc >Ld Shift the mirror base B rail downward by the half of the difference of Lc–Ld.

• When Lc < Ld When Lc < Ld, move the mirror base B on the paper feed side upward.

∗ When moving the mirror base rail, hold the mirror base rail with

your hand.

La = Lb, Lc = Ld

5) After completion of adjustment, manually turn the mirror base drive pulley, scan the mirror base A and mirror base B fully, and check that the mirror bases are not in contact with each other.

∗ If the mirror base rail is moved extremely, the mirror base may be in

contact with the frame or the original glass. Be careful to avoid this.
