Here is a good one. I have a Toshiba 357 with a strange problem. I went to replace a worn drum on this copier and after it was installed I got Horizontal thin lines randomly all over the page. Some are partially across and the other all the way.
I reinstalled the old drum and it works fine. I replaced with another new drum same problem. I order new drum from reputable aftermarket source. Name starts with a K. I installed that drum same problem. They are aftermarket drums. I reinstalled the old drum and it works fine. I have replaced the charge assembly to no avail . I checked the drum ground and they are all fine. The only difference in the new drums and the old one is that the conductive coating is all the way to the ends of the old drum. Its like the new ones are arcing with the charger in the exposed area of the drum. The exposed metal on these Known good drums are the same as the Oem Checked the high voltage connector on the frame in the back and it is not cracked. I notice a little developer on a couple bands. I checked the developer material for debris. I am going to try another dev. housing thinking the Developer spacers are worn but I fell doubtful about that. Thanks for any opinion
