1.9 ADJUSTING IMAGE POSITION SENSOR STRENGTH

AND SIDE-TO-SIDE REGISTRATION

1. Turn off the main power switch.

2. Disconnect the LCT from the mainframe.

3. With the LCT [A] separated from the

mainframe, reconnect the LCT cable to

the mainframe.

4. Turn on the main power switch.

5. Insert one sheet of plain white paper

[B] in the paper path.

6. Make sure that the paper covers the

entire area below the image position

sensor (CIS) [C].

7. Enter the SP mode and do SP1910

002 (CIS Image Position Adjustment:

LED Strength - LCT). This calibrates

the amount of light to be emitted from

the CIS.

8. Do SP1909 002 (CIS Image Position Adjustment: PWM After Adjustment -

LCT).

• If the displayed value is between 20 (14h) and 40 (28h), the CIS is

calibrated successfully. (The display is in hexadecimal code.)

• If the value is outside this range, do SP 1910 002 and 1909 002 again. If the

value does not come between 20 and 40, the CIS may be defective.

9. Exit the SP mode.

10. Reinstall the LCT to the side of the copier.

11. Push [User Tools]> [Adjust Settings for Operators].

12. Do SP1911 for Trays 4, 5, 6, 7 and set the value for each tray to "0" (OFF).

13. Exit from SP 1911 and return to the SP mode menu.
