Hi, I'd like to run this by the kyocera experts. They are always throwing me on machines I don't normally work on. Outside of some other problems I came across and spent a bit of time get around them, the main problem is dirty background. Drum & developer have 260,000+ copies. I cleaned all the normal things as in other copiers,( contacts, transfer roller,etc.) & ran drum refresh procedure 2 times. I saw in the book they mention a dirty or bad charger could cause it. I wonder if replacing it has ever fixed the problem before. I was also researching past posts and they mention 3rd party toner is bad news. The cartridge they had in there had a kyocera logo sticker on it. Since I haven't seen a known oem toner before, can I trust that this is oem ? Also when running the drum refresh the second time, it was telling me the toner was getting low, even though it felt like it was almost completely full. Would this be an indication of something ? I think replacing the drum & developer would probably fix it, but i don't want to make them buy it if it is some other kind of problem. As always, thank you for your added insight.
