MPC4500 Yellow background on Copies

[blackcircle2014]

Hi all
got a problem with yellow background on copies when using full colour ? Also leaving a multicolour mark on copies like a rainbow?

has anyone had this issue? Going to customers tomorrow to see if I can sort it.

any ideas would be appreciated

thanks

Your so-called "rainbow pattern" is the music pattern, and means that the ITB cleaning assy needs to be replaced.
As for the "Yellow background"? Probably just a drum and/or dev issue.
Difficult to say exactly, when all we have is your description of a customer's description of a problem :confused:Sounds like a pretty routine call.

No problem customer has reported this I havnt been out yet. I have a MPC4000 ITB Cleaning ASSY will this fit ? Or can I strip it down and use the parts on the 4500 one?

Also I will check pcu tomorrow and if I can't solve this I'll reply with a sample attached
