AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 20
This adjustment is needed in the following situations:
• Images are not correctly magnified in the sub-scanning direction.
• 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) 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.

5) Go through the modes specified in Simulation 48-1.
6) Select the number that corresponds to the adjustment item SPF
(SUB) using the numeric keypad.
7) Press the Start key
8) Adjust the image magnification factor by entering an appropriate
value through the numeric keypad.
9) Press the P or Start key

Repeat the above adjustments until an acceptable result is obtained.
Note: After adjusting the image magnification in the sub-scanning
direction through Simulation 48-1, do the following steps if mak-
ing a copy at a different magnification factor fails to produce a
correctly scaled copy.
