Grey left/right streaks on SRA3 paper

Jump to solution
Product Name: WorkCentre 7525/7530/7535/7545/7556
Operating System: macOS 10.13 - High Sierra

Hello,

I have made several tests using a Xerox Workcentre 7535 using different paper

sizes. It's only on SRA3 prints where I get these strange grey 2-3% shades

and borders on the left and right edge of the paper. See attached photos.

I have already tried all kinds of different printer dialog settings which don't seem to

have any positive effect on my printouts.

 

What can I do to remove these annoying grey borders on SRA3 prints?

The entry for SRA3 paper looks a bit strange on OS X with the entry "<"

I have tried all settings.

 

I already replaced the Second Bias Transfer Roll.

I already removed and re-installed the Fuser which seems to have caused a slight

change on the printing appearance of the annoying borders.

Do I need to change the Fuser? The Fuser is quite new with 99%.

 

Regards,

Black Baron

Hi,

It looks like to be from fuser. Can you upload a picture with the fuser roll?

Also try to swap the drum cartridges between them to see if the issue moves to other color.

I did that before. I attached the photos. I published and then the photos were removed.

 

Let's try it again. As usual in web development.

Take out the fuser and make a picture of fuser roll (the red one), please!

I did today after letting cooling down the Fuser for 40 minutes. I could see some black streaks on the left side of the red roll. Hm, I guess that's not a good sign?

 

The Fuser is as new 99%. Maybe it's an OEM product? Is there a difference in hardware between the

original Xerox and the OEM products?

Hi,

Ok, it is not from fuser and I don't know the diferences between original and non-original fusers (I never saw non-Xerox fuser).

So, it could be from used drum cartridges, from the Transfer Belt or from the Transfer Belt Cleaner.

The black drum unit R1 was just like new. 99%. I got grey shades from top to bottom in the middle of the page.

I changed the drum R1 with R4 to see what happens.

Result: The grey shades 2-3% in the middle of my prints are gone. The grey streaks left and right are still there.

I bought a new 100% original Xerox drum unit which hopefully arrives this week.

The prints on gloss paper now show yellowish 2-3% shades. I hope to get rid of them after installing

the new drum unit for R4. However, I don't think the grey streaks problem on left and right on SRA3 prints

will be gone. I doubt very much. A new Second Bias Transfer Roll is already installed.

 

Regards,

Black Baron

Check also, as I said, transfer belt cleaning blade. See how to remove it here.

Hi,

thanks for the advise. I got the machine used from someone working at a Xerox certified support and reseller

company and I thought. They must be knowing what they are doing. The vendor said, they entirely "cleaned"

the machine before selling it.

I made approx. 1000 prints maybe since I got the printer. Quite a lot of toner though for 1000 prints.

I think it's the Fuser unit. Whenever I remove and re-install the Fuser unit, the streaks on left

and right on SRA3 prints change slightly. I think it's the Fuser.

Hello,

I got it now. I replaced the Fuser and now the strokes on left and right side of my SRA3 prints are

gone. Furthermore, I bought a new drum R1 for black. Grey and black gradients for color matching are much

better now since I replaced it and made a color calibration on my Workcentre 7535.
