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 S
P1909 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.
