Adjustment
Adjust the threshold and operation of the sensors.
6-1
Main-scan position -platen
[-5.0 to 2.0 mm / 0.0 / 0.1mm]
Adjust the image position of the scanner to the main scanning direction.
6-2
Main-scan position - ADF
[-5.0 to 5.0 mm / 0.0 / 0.1mm]
Adjust the image position of the ADF to the main scanning direction.
Main Scan Position - Platen, ADF
1. Make a copy in platen mode at 90 rpm (speed 3).
2. Measure the difference between the center of the main-scan on the original
and on the print.
3. Access SP6-01, input the gap value and press the Enter key. (If you input a
positive value, the image moves towards the operation side.)
4. Repeat the procedure to make sure that there is no difference.
5. Make a copy in ADF mode and repeat the process using SP6-02.
6-3
Scan start position-platen
[-2.0 to 5.0 mm / 1.0 / 0.1mm]
Adjust the scan start position of the scanner.
6-4
Scan start position - ADF
[-5.0 to 5.0 mm / 0.0 / 0.1mm]
Adjust the scan start position of the ADF
1. Make copies of the test pattern printed during the previous adjustments
( previous page), in platen mode at 90 rpm (speed 3). Use the 10th print for
the adjustment.
2. The length of the 8 squares in the feed direction should be 130 mm.
3. If it is not, calculate the reproduction ratio using the following formula.{(130 -
Value) / 130} x 100 = ± X.X % (Round off to one decimal place) Example: If
the value is 133, {(130 - 133) / 130} x 100 = - 2.3 %
4. Access SP6-05, input the calculated ratio, and press the Enter key.
5. Check again to make sure that the ratio is correct.
6. Make copies of the test pattern in ADF mode and repeat the process using
SP6-06.
