Question about OKI C5100n Laser Printer
We have a OKI C5100 at our church. It's run fine for several years, but all of a sudden, started making grinding noises from within, and then flashed 540 and 541 errors. I cleaned the opticals for each of those drums, and even cleaned out all the old toner and made sure the gears on those would turn, which they seem to do. This made no difference; still get the grinding and error codes. I reset the counters on all consumables, still no diff. If I had to guess, I'd say the sound is coming from the unit under the transfer belt that has several optical sensors on it. When the gears near that unit are turned, the back of that unit slides toward the fuser, exposing the opticals, and when it gets what appears to be close to the end of its travels, that little sliding part pops back and forth as if it is stuck and a hear a little click - Not positive this is it, but best I can see! I don't know anything about these, but I'm a pretty savvy repair guy - Is this something I can fix?
