Multi-colored streak prints on right edge of page when using laser printer

My Dell 3110cn color laser printer has begun printed a streak down the right edge of the page, from the edge to about 1/4 inch in. This is usually an unprintable area. What's odd is it's streaked with Magenta toner (the most) but also a little bit of the cyan and yellow toner. No black in in that streak. And it only prints this streak when I print something in color. I've found a build up of Magenta toner on the bottom transfer roller and on the transfer belt, and clean it off, but then as soon as I print in color again, it all comes back. Looks like the Magenta toner cartridge also has some buildup of magenta toner on the outside of it, which corresponds to the streaking. If it was just printing magenta toner on this far right edge, I'd just replace the cartridge. But what does it mean if there are different colored streaks on this right edge of the paper ... not just magenta, but cyan and yellow as well? If the magenta cartridge is dumping too much toner, could that get into the toner of the other cartridges and cause them to put some toner down where it normally wouldn't? Don't want to have to buy a $100 magenta toner cartridge if it won't fix the problem! Thanks for your help.

SOURCE: Pages full of toner / toner streaking

First off, this is a comment from a random person who may or may not know ALOT about these printers and toner/printer design in general. All toners are not designed to the same specification. Toner is a combination of plastic "pigment" and iron like shavings to make it magentically attracted to the electrical charges within the unit. Different toners conform to different grades and mainly size of the particles within the blend. The manufacturer doesnt only recommend that you use their toner to make them money, yes of course it makes money, but its because when the unit is designed it is designed to use a certain grade of toner, trust me if you put the non-branded toner vs the branded toner under a microscope you would see quite a difference. Often the non-branded toner is much larger in particle size (obviousely because its cheaper to make at this spec). This causes a variety of issues from excess toner not being cleaned off of developer rollers, IDT rollers, or clogging of toner dispenser tubes in the unit and the micro filters contained at the toner dispenser assy and developer assys. Also as for the issue not changing when switching to dell branded toner - the dispenser tubes within this unit contain up to 500-1000 pages worth of toner, making no change in toner you make immediately visible. Also depending on the damage caused by the previous toner, it may not be able to be fixed until all the components in between the toner and final delivery (drum cart) are replaced. In this case more than likely the toner dispenser assy, all developer assy's, and drum cartridge need to be replaced, and than be sure to stick with factory branded toner :)

SOURCE: Dell 3100cn Smudges on all color except black

This is actually a drum issue, although changing drums doesn't always fix it. The problem is the at the tolerances between the transfer belt and the top cover of the drum is too close so the belt can scrape on the ribs inside the cover, getting a toner buildup and causing streaks in the color. Notice it is not streaking the black; this is because the black is laid on the belt last and the belt does not go around again.

This is such a flaky problem because a perfectly happy unit can suddenly start streaking because of temperature changes or, I suspect, even something as simple as moving the printer can cause things to move enough to cause the issue. A good article I have found for fixing it is at Dell forums also discuss this issue -- it's a known issue and I think Dell should fix it.

SOURCE: vertical streaks when printing pictures

vertical lines on prints usually means either the drum's cleaning blade is not cleaning the drum (or the drum is damaged) or the fuser is scored. scored means that the protective coating on the fuser rollers is damaged. I would check the rollers on the fuser (the hot part of the printer right near the paper exit) for any lines on it, if you look at your prints, you should see them in the same location on the fuser. if you do not see any lines on the fuser rollers, then replace the drum.

  11. If the image defect appears on all color pages, then measure the distance between repetitions of the defect using the ruled edges of the color test pages.
    Good Luck

Dell 3110cn Printer prints shades of pink

Have you pulled out the imaging drum and transfer roller to see if they are caked in Magenta toner? if so they will need to be cleaned off. Would also suggest blowing out the area around the drum to rid of loose toner in that area.

Dell 3110cn Color Laser Printer Certain colors will not adhere to the page when printed on heavy paper. Combination of green/black wipes off the paper when rubbed.

Either the paper is just too thick for the printer to fuse the toner correctly, or you've NOT selected the right paper type (in the printer driver options.

If you're just printing that same as you would on ordinary A4 paper, the fuser can't get enough heat through the thick paper to fuse the toner.

May be a wrong toner problem if you've done this successfully before, but only had this problem since changing toner cartridge(s)

Dell 3110cn won't print color. It shows in color on the print preview window, but comes out black & white

There's a setting in the driver that makes it print black (OK - grey scale) only.

Try that.

Dell 3110cn color laser prints with black "haze" on all pages

You probably used a "GENERIC" toner cartridge on one of your toners.

This caused the developers to get contaminated, now they need to be replaced (probably Black & Blue)
