Xerox Color C60/70 printing horizontal white line

[HannafordFS1]

As you can see from the image, my Color C60 is printing a faded line about 2/3 of the way down the page. Can anyone help me identify what is causing the issue? It has this streak across with ALL colors, and even grayscale.

In the second image you can see that it even leaves a different texture than the rest of the ink. 

The drums were all changed over the past 3 weeks, other than the magenta drum. Is this an issue with the fuser?

Hi,

It looks like there is a (or some) debris in the cyan developer housing. You will need a tech to eliminate debris or to replace the cyan developer material.

Hi Gabi,
Thank you for your reply. Would it by the cyan if it's printing it on each color?

Hi,

If it is on each color could be from IBT (image belt transfer). But to see if it is so, print seaparate pages on CMYK with 50% coverage.
