MX-M232D  (ADJUSTMENT) 12 - 2

5) Set the OC lead edge position set value (RRC-A) to [1]

 

The OC image scanning start position is shifted inside the 
document edge.

6) Set the main cassette lead edge void adjustment value (DEN-A)* to 

[1]

 

The lead edge void becomes the minimum.

7) Set the main cassette print start position value (TRAY1) to [1] and 

make a copy.

 

The print start position is shifted inside the document edge.

8) Measure the image loss R of the copied image. Enter the set value 

of the image scanning lead edge position (RRC-A) again.

• 1 step of the set value corresponds to about 0.1mm shift.
• Calculate the set value from the formula below.
R/0.1(mm) = Image loss set value

 

 <R: Image loss measurement value (mm)>

Example:

4/0.1 = 40 = about 40

Note:If the set value is not obtained from the above formula, perform 

the fine adjustment.

9) Measure the distance H between the paper lead edge and the 

image print start position. Set the image print start position set value 
(TRAY1) again.

• 1 step of the set value corresponds to about 0.1mm shift.
• Calculate the set value from the formula below.
H/0.1(mm) = Image print start position set value

 

 <H: Print start position measurement value (mm)>

Example:

5/0.1 = 50 = about 50

Note:If the set value is not obtained from the above formula, perform 

the fine adjustment.

10) Set the lead edge void adjustment value (DEN-A)* again.
• 1 step of the set value corresponds to about 0.1mm shift.
• Calculate the set value from the formula below.
B/0.05 (mm) = Lead edge void adjustment value

 

 <B: Lead edge void (mm)>

Example:

When setting the lead edge void to 2.5mm

 

:2.5 /0.05 = about 50

Note:If the set value is not obtained from the above formula, perform 

the fine adjustment.

1) Set a scale on the OC table as shown below.

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

parallel with the edge lines.

2) Make a copy, Then use the copy output as an original to make an 

SPF copy again.

3) Check the copy output. If necessary, perform the following 

adjustment procedures.

4) Execute SIM 50-6.
5) Set the SPF lead edge position set value (SIDE1) so that the same 

image is obtained as that obtained in the previous OC image lead 
edge position adjustment.
