[CQ] Mpc 3501 colour Registration

[CableGuy]

Hi all

I'm having a problem with a MPC3501 holding it's colour reg. The auto colour reg has been run in the maintance screen, sometimes needing to be done a couple of times to be spot on. The ID sensors are clean and there isn't any toner floating around where it shouldn't be. After a few copies/prints the reg starts to creep again. All the comsumables are below 50% and the ITB looks like new. I'm wondering if one of the units, dev or pcu, are perhaps dragging.
Thanks in advance for any thoughts you may have on this

Cheers

clean your optics.

run 2111-3 then 2111-1 x2
check 2194-10/11/12 they should all read 1 - if not refere to the service manual
run 3011 Normal then 3011 Full Music
check 3011 and again they should all be 11111111 - if not refere to the service manual.

Then Run the ACC.

This should set your copy quailty back to spec and then you can trouble shoot if needed e.g. sp 2109/4417 etc.
