Hello friends. for some time now I have a problem with this machine. When I have to print in black and white on paper 106-176gsm the machine to pass the sheet very quickly, so the toner does not adhere to the paper. to press the toner should I set on the machine "coated paper". in this way the sheet passes more slowly, however, it happens that this problem is in the attached. I get a magenta patch. I changed all the drum and clean the ibt, but the problem remains. this defect comes out only when I imposed coated paper. on all other media paper it does not happen. why?
