Thanks, I have found the same thing. They are completely useless. They suggested I replaced the Bias Roller, which is part of the print assembly, even though the problem is obviously a scan issue, not a print issue!
Hi there, I have a problem with a 3335 during both scan and copy: the central part of the scan present a strange band as you can see in the image.
This is a scan on the glass with the top cover opened.
Is that the lamp, the flat, the board or what ?
