MX-M232D  (ADJUSTMENT) 12 - 4

1) Remove the OC glass and the right cabinet.

2) Loosen the copy lamp unit wire fixing screw.

3) Manually turn the mirror base drive pulley and bring No. 2/3 mirror 

base unit into contact with the positioning plate. At that time, if the 
front frame side and the rear frame side of No. 2/3 mirror base unit 
are brought into contact with the positioning plate at the same time, 
the mirror base unit parallelism is proper. If one of them is in contact 
with the positioning plate, perform the adjustment of 4).

4) Loosen the set screw of the scanner drive pulley which is not in 

contact with No. 2/3 mirror base unit positioning plate.

5) Without moving the scanner drive pulley shaft, manually turn the 

scanner drive pulley until the positioning plate is brought into 
contact with No. 2/3 mirror base unit, then fix the scanner drive 
pulley.

6) Put No. 2/3 mirror base unit on the positioning plate again, push the 

projections on the front frame side and the rear frame side of the 
copy lamp unit to the corner frame, and tighten the wire fixing 
screw.

MX-M232D  (ADJUSTMENT) 12 - 5

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 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 
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. 

La = Lb

6) Execute the main scanning direction (FR) distortion balance 

adjustment previously described in 2) again.

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. 

4) Enter the set values of the items of F and R, and press [START] 

key. 

 

The correction values are saved and a copy is made.

MX-M232D  (ADJUSTMENT) 12 - 6

Note: A judgment must be made with 200mm width, and must not be 

made with 100mm width.

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, and make a 

normal (100%) copy.

2) Compare the scale image and the actual image. If necessary, 

perform the following adjustment procedures. 

3) Execute SIM 48-1.
4) After completion of warming up, shading is operated and the 

current correction value of the sub scanning direction magnification 
ratio is displayed on the screen.

5) Select [2.SCAN] mode with the cross cursor.

6) Enter the set value and press the start key.

 

The set value is stored and a copy is made.

Note:
•Before performing this adjustment, be sure to check that the CCD unit 

is properly installed.

•Before performing this adjustment, the OC mode adjustment in 

copying must be completed.

1) Put a scale on the original table as shown below, and make a 

normal (100%) copy to make a test chart.

Note:Since the printed copy is used as a test chart, put the scale in 

parallel with the edge lines.

2) Set the test chart on the SPF and make a normal (100%) copy. 
3) Compare the scale image and the actual image. If necessary, 

perform the following adjustment procedures. 

4) Execute SIM 48-5.
5) After warm-up, shading is performed.
6) Check to confirm that the RSPF (SIDE1) mode is selected with the 

cross cursor.

7) Enter the set value and press the start key.

 

The set value is stored and a copy is made. 

* “RSPF (SIDE2)” is displayed only when the RSPF is installed.

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. 

3) Execute SIM 50-12.
