Hello I have a problem with my Brother T820DW printer, that when I'm printing a document eg pages 1-100, somewhere along the way, maybe after 40/50 pages, it will randomly start printing page 1 again. This is really frustrating as I leave my printer to print while I do other work, only to find that it has wasted ink and printed the beginning pages of the file 2 or 3 times. First I thought its because my USB port is a bit loose, so I connected the printer wirelessly, only to experience the same problem. Please help!
