Hello guys,


Getting hotizontal lines in ALL Color Copies.

Prints and Monochrome copies are all 100% Fine.


In my years of service I’ve never seen this before. Thought it could be a print-heads or Lasers but not certain. Image units are all Okay.

Any suggestions/Ideas..?? Thank you.

Time to thoroughly clean those optics. Some things show up more in the color spectrum than in B&W.

If color and B&W prints are good, then all print engine items (lasers, drums, devs, fuser) should be fine.



EDIT: If a thorough cleaning of the optics doesn't fix then it could be the CCD unit. Cleaning is cheaper.

EDIT2: The samples look like it's for sure in either the CCD or image processing.

Did you try color scan to PC?
If something wrong (or dirt) with optics it should be seen on scan too.

Good point that will split it up between optics/CCD and possible processing problems.
I will wack it with a cloth and reconnect relevant connectors.

But an old ninja trick is to make reductions and enlarged copies.:p
If the marks stay were they are at well not so good news...

Coming from a guy who can't get firmware onto a copier.:eek:

Good suggestion. If the lines follow the reduction or enlargement, it's in the optics.

That's completely bizarre!

The anomalies are too regular and too consistent, and not matching any interval I recognize. I think I'd try re-seating the CCD cables first, replace CCD second.

Definitely scanner or image processing caused.

I just had a thought: The color variation of the stripes is mainly changes in Red, since the CCD scans lines of red green and blue, not CMYK. =^..^=
