4650DN color registration

[Cirrus]

Magenta on this printer out of registration. I am not finding any manual registration. I cleaned the color registration sensors and ran full calibration. Could anyone please give me an idea. The customer is a distance from me and I already spent too much time to give them no real answer.

thanks

Here is the calibration procedure.

the ETB, the drum drive motors, the drum drive gears, or a laser/scanner.

Update the firmware and run 3 calibrations back-to-back. If still no luck, I'd start with replacing supplies (magenta cart, then ETB), followed by DCC. Normally F/W and Full Calibrations take care of this.
