ok ive been doing this a long time but im stumped
there is a little black mark on the copy that looks like a staple 2 little marks next to each other in the print direction I replaced the drum no help although the drum was badly worn
cleaned the optics cleaned the slit glass under the drum pulled the transfer belt the mark was on the belt but wiped right off the belt is in very good condition I pulled the developer unit rotated it thinking some crud was on the mag roller but nothing it looks fine this is a phantom mark I can not find a cause for I really thought it would be in the dv unit Im stumped any help would be appreciated thanks
