=================================
_Did u try performing a REG CLR in service mode level 2_?
REG CLR in service mode level 2: Copier > Function > Clear > REG-CLR.
_After the clear, do a auto color mismatch adjustment
Also_
Check the Shutter on the Patch Reader and clean the Registration Sensors.
Make sure the lens that covers the registration sensors is not scratched and causing a misread of the registration patches on the ITB Belt.
Registration Sensor Units may need to be replaced.
It has also been found that if the values under COPIER>ADJUST>IMG-REG are set to 0 color mismatch will fail.
Enter the values from the front door label.
The issue may be caused by a faulty Patch Shutter operation. The Patch Shutter is operated by SL1 ( Registration Shutter Solenoid ) and a Shutter linkage. Verify that the Shutter linkage and Patch Shutter moves smoothly, and check the operation of SL1.
To check the Patch Shutter & SL1 operation: Remove the ITB Belt front cover and locate SL1. Actuate the front door switch, enter Service Mode, Function, Part check, <SL=1>, and activate SL-ON.
___Correct any binding and/or replace any defective components.
