Immediately after color pm we started having issues with the cyan and yellow colors. Everything with those colors washed out. After fooling with it for an afternoon I put in just a single color, yellow, that we had sitting around. I stirred that up and checked the copies and still had a problem. I have checked developer voltages, toner motors, cleaned the toner pipes. We have not done another complete dv change yet. Any ideas welcome.

Re: MX-4501 copy quality issue immediatly after color pm.
Change the process electrode covers on the rear frame of the machine. There is a mod for this. Also check LSU chutters. Another common issue is the transfer belt clutch slips causing the belt to lose tension. There is a mod for that as well. this can be easily seen by cheating front door and running test sim -

The charge rollers in the primary transfer belt unit can cause that sort of problem if they are dirty at the ends where the HV connections are - worth a crack?
I thought i was the only one in the world with machines of this vintage?muppet is as muppet does!

Hey, Thanks guys. I think that I remember the electrode covers while scanning some of the bulletins years back. Be cool if I could transfer you guys a cold refreshing beverage of your choice!
