Repeat steps 2 to 9 until the image magnification factor is satisfactory.
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 direction.
• The MFP control PWB has been replaced.

1) On the SPF original tray, place such an original as illustrated
below.
2) Make a normal copy on A4 paper.
3) Measure the lengths of the copied image and the original image.
4) Determine the image magnification factor using the following for-
mula:
Image magnification factor (%) = Copy dimension/original dimen-
sion x 100
sion x 100
Image magnification factor (%) = 99 / 100 x 100 = 99
If the image magnification factor is within the spec (100±0.8%), no
adjustment is required; otherwise, do the following steps.
