MX-5001N ADJUSTMENTS 5 – 39
2) Enter the simulation 48-1 mode.
3) Make a normal copy and obtain the copy magnification ratio.
Press [CLOSE] key to shift from the simulation mode 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 (MAIN) adjustment value of Simulation 48-1.
When the adjustment value is increased, the copy magnifica-
tion ratio 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%).
14-B Scan image magnification ratio adjustment
(Sub scanning direction) (Document table
mode)
1) Place a scale on the document table as shown in the figure
below.
2) Enter the simulation 48-1 mode.
3) Make a normal copy and obtain the copy magnification ratio.
Press [CLOSE] key to shift from the simulation mode 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%).
ADJ 15 Scan image magnification ratio
adjustment (RSPF/DSPF mode)
15-A Scan image magnification ratio adjustment
(Main scanning direction) (RSPF mode)
15-C Scan image magnification ratio adjustment
(Main scanning direction) (DSPF mode)
This adjustment must be performed in the following cases:
* When the scan control PWB is replaced.
* When the EEPROM on the scan control PWB is replaced.
* When U2 trouble occurs.
* When the copy magnification ratio is not matched.
* When the RSPF/DSPF is disassembled.
