C-3232E with cyan background. I recall reading somthing abaut this but cannot find it.It only happens in color mode and the copies don't have alot of blue on them yet I still get cyan background
Could the DV bias for the CYAN unit be out of adjustment. I just did the spring and drum drive coupling modification. Could a bad spring in the drum unit possibly be causing your problem. I think the Tech Bulletin that discussed the spring problem is 8501. It talks about getting service call of either C5101,5102,5103 ro 5104: Main High Voltage errors K/C/M/Y due to poor fitting of the Drum Coupling. Maybe this could be contributing to your cyan background problem.
Dummie it's off the glass. I don't know what chart the tech was using. I'm taking over the problem tomorrow. I did have him check Sim 107 & "68 prior to knowing it was of glass" and he tried a DV Unit today.The coupler & spring that elheather mentioned I will look at tomorrow. Thank's

I just had this problem recently and mine ended up being the drum drive coupler was sticking, I ended up taking the dv and drum units out and lubed the coupler drive system and it has been working fine.
Dusting, cleaned and cleared up in 15 copies is what was reported back to me "Laser slit glass" I had to go somewhere else. I really thaught it was going to turn out to be what techboy was talking abaut drum coupler or what Dummie you said drum ground. My point is why is it dusting and it will probally come back,it doesn't have background right now but time will tell.

Just had a similar background problem on a CS-C3232E. I immediatly went for the DV units cause you know how must toner they can spew all over themselves and the adjoining drum unit, when that failed to fix it I went after the main charge rollers and inspected and cleaned any toner dust from that area, still with no luck. Customer is running a print job to the copier and using 80# cover and has the bypass tray set to "COVER" on the media type. They say they don't run it often but those are the settings it has worked best with in the past. Called Tech support (Thanks Tom), and he had me change the paper type setting to "BOND" which is the highest fuser temp setting that the copier can operate at. I was skeptical at first that this simple change would correct what I was seeing, since it didn't appear to be ghost imaging the same image offset from the main image, just some overall background toning. Well, ran 5 test prints at first, all looked good, stepped it up to 25, still OK, then ran a 50 set print job. All the prints came out with no background, once again, Thanks Tom.
I've had main charge rollers give me this problem as well. Swap the cyan main charge with another color and see if the problem moves. I've seen this on a few machines... gets worse and worse over time. Going into U100(Adjust DC2 I think) and bump up the offending colors main charge value by 20 you can usually get rid of it for a while. Eventually it will come back and need a drum/main charge replacement.
I also wonder what other adjustment/corrections are made to the bias voltages when you select bond over plain paper type. It would make sense that the transfer bias voltage would get minor changes made to them because of the different paper type. Anyone else with insight into this.
sky : did you use a color test chart to test ? i need 2 to know if u are using the glass or the df or ur printing need more info...
