[Misc] c3350 Splattering black all over prints - Yet comes out as black on halftone tests.

[HarryBurgess]

Hi, got a c3350 that when printing anything leaves a black splatter all across the page. So I go to do the halftone test prints and all colours come out ok (still with the splatter) however the black halftone comes out as a blank piece of paper.

Any help would be greatly appreciated. Thanks.

Not only would a sample be nice, but a little more info on machine and PM counts nice as well. Is the toner OEM or generic?

Here is a magenta and black halftone test print, what appears on the magenta appears on all other prints.

We received the copier off a supplier filled with OEM toners. We usually remanufacture them and send them back out. I can't find the counts as nothing shows when printing black pages except as shown on the attached image.

Check consumable status under the Utility key. Is the K image unit overdue?


Inspect the surface of the Black image unit , Transfer belt , and fuser unit to see if there are any marks or residue that correspond to what you see on the prints.

This issue will probably be resolved for you by replacing the Black image unit Part# IUP-22K

I would start with a black pcu, first. Is there a supplies status page available? Have you gone into the menu, counter icon?

I have replaced the fuser previously and it had no effect. I don't think it could be the transfer belt as it appears to be only k having this problem. I have just swapped the black imaging unit and the print has gone inverted. As seen in the image attatched.

I have swapped the k imaging unit twice and still the same result, and as for the supplies status page everything seems to be normal. The copier itself has done around 60k prints in total so not extremely high. I was thinking it could may be to do with the charge?

The unit that made these images probably has wrong toner in it.

The original unit probably is just worn out. You'll see the pattern in the drum when you remove it.

So what are you suggesting I do to resolve this? As I haven't had any luck with new drums and I'm not sure that a new toner would work.

Also how come it is appearing on every print? Even the ones without any black.

Re: c3350 Splattering black all over prints - Yet comes out as black on halftone test

The black drum remains in contact with the primary transfer belt on all images, and the imaging unit components rotate on every image.

By contrast a B&W only image is made only with the black imaging unit, the other color units do not rotate.

I'm sorry that your afraid to install a new black imaging unit, but that's whats needed. =^..^=

You know, I get the feeling that you're not comfortable doing this repair. That's fine. I'm sure there's someone in your area capable of doing it.

I agree with blackcat that it looks like the wrong toner was used. You say that the toners are OEM but that doesn't mean that the OEM carts. weren't refilled with compatible toner. You need to clean all the black toner out before installing a new drum. Just make sure no toner is in the toner pipe before installing a new drum.

Afraid? I've stated that I have already done what you are telling me to do twice and there has been no change. I don't think you quite understand what I am saying.

I could probably install a new imaging unit before I knew how to tie my laces as a kid

But your time and help is appreciated nonetheless.
