Static-Like image on MX-M260

[Madnhain]

The MX-M260 will print fine, when scanning it overlays the image with a layer of grey "static", while the original is not distorted with the exception of light horizontal lines that look like they would be from the drum, however when printing they do not appear.

Scanning to a computer comes up with the same result. Fax is the same as well. Printing results are normal so we know it is an optical issue. We have ordered and replaced the CCD with no change.

Has anyone seen anything like this?
Attached is an image of a fax attempt (note the print on top is fine) and also a copy of an original.

First step would be to perform a shading adjustment with sim 63-2, making sure your white level reference plate on the underside of the platen glass is cleaned.

My next guess - provided the first wasn't the solution - would be that perhaps you have some corrupt scanner memory. Have you tried reseating it and/or cleaning it off?

Looking at your image, you can see it doesn't run edge to edge, so the mechanics of the copier are still in check. I would be inclined to think the issue lies with the scanner assembly, either in the electrical level (scanner PWB/ROMs) or a physical one with the optic carriage itself.

Was your image scanned long edge feed or short edge feed?

Thanks Akitu, we found the solution, as it turns out the CCD was the problem after all. We didn't adjust the CCD along it's slides according to the sharpie-hand-written 0.1 on the CCD itself. So the new CCD was in effect giving us the same result because it was out of adjustment. (nowhere is it written in any manual to do this) Our senior tech figured it out after he thought about it for a few minutes.
