All mecanisims are working toner flows properly with out cloging up the problem is too much toner is getting into the recycle conduit . Ive adjusted the drop ratio on hopper digital adjustment (lower) and increased the recycle motor time. I do get the sc code after so many copies then i have to dig out all this toner. The code goes away for a month they are running 30k a month is there any resolution to this hopefully i wont need to flash the rom on this thing dont have a clue on how to do this
