MX-M700N ADJUSTMENTS 6 – 16
Repeat the above adjustments until an acceptable result is
obtained.
ADJ 6
Adjusting the image
magnification
6-A
Adjust the image magnification in the main
scanning direction in original table mode
(CCD)
This adjustment is needed in the following situations:
* The CCD unit has been removed from the machine.
* The CCD unit has been replaced.
* Images are not correctly magnified in the main scanning direc-
tion.
* The MFP control PWB has been replaced.
* The EEPROM on the MFP control PWB has been replaced.
* The scan control PWB has been replaced.
* The EEPROM on the scan control PWB has been replaced.
* U2 trouble has occurred.
1)
Place a scale on the original table in parallel with the main
scanning direction, as illustrated below.
2)
Make a normal copy on A4 paper.
3)
Measure the lengths of the copied image of the scale and the
actual scale.
4)
Determine the image magnification factor using the following
formula:
Image magnification factor (%) = Copy dimension/original
dimension x 100
Example: Compare the copy and original dimensions by align-
ing the scale's 10 mm position with the copied image's 10 mm
position.
Image magnification factor (%) = 99 / 100 x 100 = 99
If the image magnification factor is within the spec (100
r
0.8%),
no adjustment is required; otherwise, do the following steps.
5)
Go through the modes specified in Simulation 48-1.
