This is caused by one of two things.
1) One of the handles on the toner cartridges is not seated all the way down. 90% of the time, this is the problem, and of that, most of the time it is the cyan cartridge that is not seated properly.

2) there is toner covering part of the print head. Sometimes this is just a temporary problem that can be fixed by simply cleaning the printhead lens with the cleaning wand. ( i will explain that in a moment). If cleaning the printhead works, but then the problem reappears shortly afterwards, then you have a more serious problem in that the developer housing for one of the toners is defective and leaking onto the printhead. When cleaning the printhead, make note of the most prominent color on the cleaning wand pad, as this is probably the defective housing's color.

To clean the print head
a) Open the front cover.
b) on the right hand side, slide the lite blue handle forward. This will open the access hole for the cleaning wand on the right hand side of the printer.
c) pull the cleaning wand out ALL OF THE WAY until it comes to a stop. Then slide the wand back in ALL THE WAY until it can not go in any further.

Repeat step "c" several times.

DO NOT move the wand back and forth unless you pull it all the way out and all the way back in. This will only smear the toner back and forth across the print head. when it is pulled all the way out it hits a lift that will lift it up and over the print head on the way back so it does not move backwards across the printhead.

the fuser is fine, and one of the two solutions above will fix your problem.

as I said though, if the problem is quick to return, then one of the developer housings are leaking.

When I print from the internet my copy prints my color comes out a different color I think it might be my black ink is off I have a dell 946 all-in-one printer.

Are you using Dell Series 5 ink cartridges?

Can you copy a document under the glass? Black & White and color? Do they look ok?

If you unplug the printer from the wall and remove the power brick for 60 seconds, this will reset any error messages the printer has. I would then plug everything back in.

Power on the printer.

Open the printer(with the power on) and take out the Dell Series 5 black cartridge and then reseat it. I would then take out the color Dell Series 5 ink cartridge and reseat it. Now close the printer and it will print an alignment page.

Any error messages?

black cartridge = black side(left side) color cartridge = color side(right side)

photo cartridge = black side(left side) color cartridge = color side(right side)

Dell Series 5 ink cartridges have a sensor in them that cannot be reset. Article on refilling Dell ink cartridges .

Dell Series 5 ink cartridges can be purchased at Staples, Walmart or Dell's Website.

It's possible to get a Dell Series 5 ink cartridge with a bad sensor. I would that these back to the place of purchase for a replacement or a refund.

This has to do with the document printing properties. When you are ready to print a document, choose properties and make sure you go through the printer settings under that software.
The test page only verifies the cartridges. The printer properties of the software control the printer during printing.

I have a brother MFC 3240C. My Black ink stopped printing(initially printed horizontal faded lines and gradually got worse), the other colors were printing fine. I tried cleaning numerous time( 50 -100 times over 1-2 weeks ). Still no improvement. The way I print now is:
1. I go to Printer Properties
2. Change Media type from "Plain Paper" to "Inkjet Paper".
3. Change Quality to "Photo".

This takes a long time to print 1-2 minutes per page. However, this works for me since this is my Home printer and use it for printing only few pages here are there.

Good Luck

1/2" white line appearing down right side of page

Try replacing the toner cartridge. This seems to be a problem with the photo-sensitive drum, which is located in the cartridge.

I have fading on the right hand side. Printer Dell 3100CN

Dell printers are junk. But you have put a lot of money into this thing. Check the alignment of the black drum, could be that something is keeping if off track a little bit.

Color when I PRINT

actually, I bet you cannot print text either. It will come out very faded or completely blank. It is an issue with the printhead, on the black ink cartridge side.
You can try cleaning it using the printer itself (Menu -- clean printhead -- deep clean ).
IF you have the same problem, contact kodak aio support @ 1 800 421 6699 (open til midnight on ET) or go to and follow the troubleshooting steps there to fix the problem or replace the PH.
