Hello Tech9 Here is what happened. For some reason the black toner cartridge was spilling toner into copier everytime it rotates in the copier. I took out the cartridge and then took out the black developer housing and then not knowing what I was doing I tried to remove the three screws on top of the developer housing. after I put it back the code appeared. The same problem, (toner leaking) was happening to the yellow cartridge as well. I got two new developer housings for black and yellow and replaced it and it still would not get rid of the error 092-310. I finally got into the UI diagnostics mode. with the new housing units that I just ordered was a paper saying that I should reset some NVM locations to 0, which I did but it still does not work. I turned off and On the machine and still nothing works. Do you think that I need to order some parts for it to work? Thanks Screwdriver08
