AR-M550/M620/M700 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
Example: Compare the copy and original dimensions by aligning
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.
5) Go through the modes specified in Simulation 48-1.
6) Select the number that corresponds to the adjustment item CCD
(MAIN) using the numeric keypad.
This adjustment item is intended to adjust the image magnification
in the main scanning direction in original table mode (CCD).
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
Pressing the Start key starts copy operation as well as applying the
adjustment value.
Repeat steps 2 to 9 until the image magnification factor is satisfactory.
