MX-3114N ADJUSTMENTS AND SETTINGS 5 – 75
16-B Scan image magnification ratio adjustment
(sub scanning direction) (Manual
adjustment) (Document table mode)
This adjustment must be performed in the following cases:
* When the copy magnification ratio in the copy image sub scan-
ning direction is not properly adjusted.
* When the scanner motor is replaced.
* U2 trouble has occurred.
* When the scanner control PWB is replaced.
* When the EEPROM of the scanner control PWB is replaced.
1) Place a scale on the document table as shown in the figure
below.
2) Enter the SIM 48-1 mode.
3) Make a normal copy and obtain the copy magnification ratio.
Go to the copy mode, and make a copy.
4) Check that the copy magnification ratio is within the specified
range (100 1.0%).
If the copy magnification ratio is within the specified range (100
1.0%), the adjustment is completed. If the copy magnification
ratio is not within the specified range, perform the following
procedure.
5) Change the CCD (SUB) adjustment value of Simulation 48-1.
When the adjustment value is increased, the copy magnifica-
tion ratio in the sub scanning direction is increased.
When the adjustment value is changed by 1, the copy magnifi-
cation ratio is changed by about 0.1%.
Repeat the procedures 3) - 5) until the copy magnification ratio is
within the specified range (100 1.0%).
