Have a machine where one of the colors is dropping out or is very light , it can be Cyan, magenta or yellow , or maybe a couple at a time , I know the image is on the drum when it does it but it is not getting transfered for some reason , tried the board inside the belt unit no difference , sometimes it works fine black never has a problem , any ideas ? I am going back tomorrow with some of the other boards that are tied into transfer.

I've seen the developer units not moving smoothly into and away from the OPC. Make sure the guides for the developers are clean and free of any crap. I've also seen clutches in those machines contaminated with silicone oil, usually on the paper feed side, but the dev clutches can go too. -
Is it all the time or intermittent? How old is the developer? Have you tried running single colour copies from service mode? See if one of them shows up anything.Comment

It is intermittent , cant be developer or drum related the image is on the drum when it does it, does it in single color also.Comment

Is the image making it into the ITB? There could be intermittent transfer from OPC to ITB. Are there any class C or D SC's being logged? Is it passing process control?Comment

On this machine the image doesn't get transferred to the belt , the paper goes between the belt and drum and the image gets transferred from the drum directly. Anyway I went there today and of course it wasnt doing it but I swapped the BCU board anyway and will see if problem pops up again.Comment

Sorry my bad, I was just reading a thread on a different machine and jumped in with the wrong product in mind.
I had one of these where the transfer unit position sensor was causing the unit to not reliably position itself, perhaps checking or changing that may help.Comment

Correct if I'm wrong but is'nt this the same system as the AF1224 where the image from the drum is transfered to the transfer belt and then to the paper by means of the transfer roller fitted on the right hand side door. As afr as I know they even use the same Drum / TB unit hence it must use the same system of image transfer. I would look at the tansfer roller especially if it is mounted right and not havein that black mylar inbetween the contact and the roller endVoluntary assistance can be your greatest gift once you do not degrade the recipient.

It's a B190, I thing he meant to put 3228c.Comment

It is a Savin 3224 which is the B190 also the same as a Savin 2820 and 3828 just different speeds , and the image gets transferred directly to the the paper from the drum it does not go to the transfer belt then the paper.Comment

ok I have summer 2009 manuals an they say Savin 3224C = B147. Besides the point a little. There is a copier to fix.
I think you are going in the right direction with transfer. If the image is indeed on the drum. Does the problem go away with process control? I'm thinking power distribution. Obviously I'm guessing a alittle without seeing the machine. If something is shorting and pulling down either drum charge or transfer charge.Comment

I have replaced the BCU and it hasn't done it again in almost 3 weeks, thanks for the tips !Comment
