Image Adjustment

Overview

"Image Adjustment" adjusts the image position on prints by changing the SP settings.
Adjust the settings in the order:
• SP6-10 6-21 6-5
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 100 rpm (speed 2). 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)
5. Example: If the value is 133, {(130 - 133) / 130} x 100 = - 2.3 %
6. Access SP6-10, input the calculated ratio, and press the Enter key.
7. Repeat the procedure to make sure that the ratio is correct.
