5.7.3 IMAGE ADJUSTMENT (SP6-10, -21, -5, -3, AND -1)
Purpose: To adjust the image position on prints by changing the SP settings.
Adjust the following in the given order.
When correcting errors made when printing with the controller, use only the first
two procedures. When correcting errors made when printing with scanned
originals, do all six adjustments in the given order.
This adjustment is required every time the RAM on the MPU has been replaced.
SP6-10: Master writing speed
1. Input SP8-10 (Test patterns) and enter “6”, then press the Start key.
2. Exit the SP mode, print 10 copies at 90 rpm (speed 3). Use the 10th print for
the adjustment.
3. The length of the 6 squares in the feed direction should be 130 mm, as shown
above.
4. 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 %
5. Access SP6-10, input the calculated ratio, and press the Enter key.
6. Repeat the procedure to make sure that the ratio is correct.
SP6-21: Paper registration position
1. Input SP8-10 (Test patterns) and enter “6”, then press the Start key.
2. Exit the SP mode, print 10 copies at 90 rpm (speed 3). Use the 10th print for
the adjustment.
3. The space between the leading edge and the next line should be 11 mm, as
shown above.
4. If it is not, access SP6-21, input the difference and press the Enter key.
Example: If the value is 16 mm, 16 - 11 = +5.0
5. Repeat the procedure to make sure that the gap is correct.
