Sharp MX-M550U

MX-M700N ADJUSTMENTS 6 – 20
6-E Adjust the image magnification in the sub-
scanning direction in DSPF mode
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 DSPF 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
formula:
Image magnification factor (%) = Copy dimension/original
dimension x 100
Image magnification factor (%) = 99 / 100 x 100 = 99
If the image magnification factor is within the spec (100r0.8%),
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.
This adjustment items is intended to adjust the image magnifi-
cation in the sub-scanning direction in DSPF mode.
(SPF (SUB))
7) Press the Start key.
8) Adjust the image magnification factor by entering an appropri-
ate value through the numeric keypad.
9) Press the P or Start key.
Pressing the Start key starts copy operation as well as apply-
ing the adjustment value. Repeat the above adjustments until
an acceptable result is obtained.
* After adjusting the image magnification in the sub-scanning
direction through Simulation 48-1, do the following steps if
making a copy at a different magnification factor fails to pro-
duce a correctly scaled copy.
1) Go through the modes specified in Simulation 48-5.
