Black looks great, color off just enough to make you think you been drinking a bit too much.

What steps have you taken? Single copy? Multi-page run?

You forgot to mention the P-31 code you are getting.
The encoder disk on the K drum drive is probably soiled.

Don't think of cleaning it get a new encoder disk. Or rather a complete new drive.
Good luck its a fun job.

Then it could be an IDS problem bad ITB or dirty ID sensors.

Do a print head skew reset then power cycle, this usually gets rid of color reg problems that are not caused by IU/ITB problems. Emujo

clean the reg sensors and do an intialize and reset.

Where are the sensors that I need to clean?

open the right door and remove the belt. the two sensors are located on the black plate just under where the belt sits. move the shutter and blow air in them
