White Lines During Printouts

mklinger, this can be caused by a blockage in the developer unit which prevents that particular area on the developer roller from receiving toner. The developer roller normally has blades immediately above and below it which scrape off excess toner. A small lump of damp toner may block the gap between one of these blades and the developer roller, thus causing your problem. Get the parts list from here and I added the disassemble part from the service manual to this site. Just scroll all the way down to "Documents". Hope this helps, good luck.
