[decacazza]

Hello everyone I have a problem on uns bizhub 500: the copier and then sprinkle the sheets of paper I have left dirty or stained, I think it's the developer to replace the car has 830000 copies and I do not know the work carried out previously.
after replacing the developer what is the procedure for calibration?
thank you very much

Run a TCR Adjustment.

Service Mode -> Image Process Adjustment -> TCR Adjust -> Start and let it run.

Make sure you clear the counter in service mode as well so you know when it was replaced in case you get quality issues again in the future.
