At first I thought this was due to the generic toner my company uses,the stuff sucks. It seemed to happen when the toner would run out and the new toner installed. Twice it has blown the toner sensor in the developer unit. Developer has been changed both times and I even installed a different developer unit. We now are running oem toner in this and now today we got this code again. I am not the tech that went out today but it seemes to have happened when it ran out of toner. Anyone seen issues with this model?
