<Notes>
• This describes the adjustment procedure in the standard operation; however, adjustment of tilting in
the laser optical unit has sometimes been carried out on the manufacturing line and the scales of the
frame and the LSU holder may be aligned at a position other than the center.
In this case, move the scale position only by the required volume to be tilted since the ones of the
frame and the LSU holder have aligned.
Obtain the value in accordance with the following condition when moving the scale.
• A3 size paper (Width: 297 mm): The value of A-B becomes smaller by approx. 0.14 mm per 1
scale.
• LD size paper (Width: 279 mm): The value of A-B becomes smaller by approx. 0.13 mm per 1
scale.
• If the value of A-B is plus, use the scale in the front side.
• If the value of A-B is minus, use the scale in the rear side.
E.g. 3: The second scales on the front side are
aligned and the value of A-B is approx. 0.5 mm
• Since the value of A-B is plus, move the scale to
the rear side. Since the value of A-B is approx. 0.5
mm, move 4 scales.
• Move the LSU holder by 4 scales to the rear side
from the second scale on the front side, so that the
sixth ones are aligned.
(8) Secure the screw temporarily tightened in step (5).
(9) Tighten the screw [8] loosened in step (3).
(10) Output a grid pattern of A3/LD size and check whether image tilting has occurred or not. If this
problem still persists, return to step (3) and perform the adjustment again.
• The tilted volume of 0.5 mm or -0.5 mm can be adjusted in a simplified method.
For details, refer to "6.7.2. Adjustment of image tilting at the leading edge [2] Adjustment of the tilted
volume by 0.5 mm with a simplified method" in the Service Manual.
