AR-M550/M620 SETTING AND ADJUSTMENTS 7 - 16
Repeat the above adjustments until an acceptable result is obtained.
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.
• 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.
3) Place a scale on the original table in parallel with the main scan-
ning 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 for-
mula:
Image magnification factor (%) = Copy dimension/original dimen-
sion x 100
sion x 100
Example: Compare the copy and original dimensions by aligning
the scale’s 10 mm position with the copied image’s 10 mm posi-
tion.
the scale’s 10 mm position with the copied image’s 10 mm posi-
tion.
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.
