(3) Main scanning direction (FR direction) distortion
adjustment
This adjustment must be performed in the following cases:
• When the mirror base drive wire is replaced.
• When the lamp unit, or No. 2/3 mirror holder is replaced.
• When the lamp unit, or No. 2/3 mirror holder is replaced.
• When a copy as shown is made.
1) Set A3 (11" x 17") white paper on the original table as shown below.
2) Open the original cover and make a normal (100%) copy.
3) Measure the width of the black background at the lead edge and at
the rear edge.
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
(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.
5) Tighten the mirror base drive pulley fixing screw.
<Adjustment specification>
La = Lb
6) Execute the main scanning direction (FR) distortion balance
adjustment previously described in 2) again.
(4) Main scanning direction (FR direction) magnification
ratio adjustment (SIM 48-1)
Note: Before performing this adjustment, be sure to check that the CCD
unit is properly installed.
1) Put a scale on the original table as shown below.
2) Execute SIM 48-1.
3) After completion of warming up, shading is operated and the current
correction value of the main scanning direction magnification ratio is
displayed on the screen.

<Adjustment specification>
* “RSPF (SIDE2)” is displayed only when the RSPF is installed.
(6) Off center adjustment (SIM 50-12)
a. OC mode (SIM50-12)
1) Make a test chart as shown below and set it so that its center line is
fit with the original guide center mark.
* To make a test chart, draw a line on A3 or 11" x 17" paper at the center
in the paper transport direction.
2) Make a normal copy from the manual paper feed tray, and compare
the copy and the test chart.
If necessary, perform the following adjustment procedures.
