Canon ImagePress C650 auto correct color mismatch fails, mismatching colors issue

[DMP]

Just to confirm, at this point I should not perform cleaning of registration patch sensor or still should do it?
On our old machine C5235, when one color drum goes bad I used to replace all the rest color drums. Should I do same with the C650 or replace only cyan?
Do you happen to have part numbers for the following:
Color drum (for each color or all 3 colors are same?) copier has a bit over 500k pages.
starter part number?

Can you reference page number on service manual for the said procedures also steps to get to the procedure guide in service mode?

Thanks so much for your help!

Ok good .
Its a drum issue , the patches are not printed properly on the belt to be read by the sensor. Replace the cyan drum .

Dont forget to go through the replacement procedure in the service mode .

Check the developer cyan if starter is falling from it on the bottom scrapper , (not toner) . Better replace if starter are falling, else only clean it.

Best of luck

Dont clean anything , just replace the drum.

Go service mode - > situation -> parts replacement -> replace drum

Only replace the cyan drum , for 500k the developing should be good, no need to change it, but better check it and clean it .

Not sure if you received my private message. I am not finding "situation" menu on either service mode 1 or 2. Is it somewhere else?
Thanks,
