FO2080/2081's Pulling developer

[BryanW]

Has anyone had any issues with these units pulling developer and laying it on the copies? I have had an FO2080 in place for a year and all was fine until now. I have 3 machines, all of a sudden, pulling developer. The 3 machines are in 3 seperate locations. The FO2081 is brand new and has gone through 3 toner/dev units in 3 weeks and the two FO2080's have gone through 1 each in the last 2 weeks. We have checked voltages and bias and all are fine.

Replace the transfer unit in the right door.

Bryan,just wanted you to know I just posted about an FO-2080 pulling developer on front side of machine and causing lighter images on front side about an inch wide starting at front edge of drum. I changed drum unit, td cartridge and transfer corona and though it doesn't seem to be pulling developer now the image is still lighter on front edge. Frank/ActionPhotocopy

Is it possible your laser got dusted a bit?

Thanks.That's an excellent point Lawrence seeing as that would cause a gray rather than black image.Frank

Recently I installed several 2081s and soon began to have similar dev pulling. Any solution for your issue?

I would imagine that non OEM toner /developer non OEM process unit might pose a problem if not compatible. Frank

I agree the transfer is most likely the problem, but you should also check the drum.

The drums can wear the outer coating off and this will cause the main charge to short out.

This will also cause the developer to be pulled out.

Reason I did not mention transfer was because it was mentioned several machines pulling developer at same time which to me is more of a possible indication of supply proble. Frank

This has been going on since the early AL-series machines. It's the scortron in the drum unit. Pull it out, clean it, make sure the saw tooth hasn't come un-glued from the plastic. This will start as a black line down one edge of the paper. If you don't fix it, it will suck out all of the toner and then start on the developer.

Seen it, oh...I don't know, 1,000 times.
