Magenta streak running length of paper

There is a bad spot on the magenta toner cartridge TN 110 - is there a way to clean the cartridge? It's not close to being empty so I really don't want to buy a whole new cartridge.

The model is Brother MFC-9840CDW

Any suggestions will be greatly appreciated.

Thanks,
Misty

Only my magenta toner streaks, too. That's odd and cannot be just a coincidence.

Have you tried cleaning the corona wire? You can also use a cotton swab and clean the drum. Just be sure to unplug the unit from the wall and allow everything to cool down.

Cleaning the Corona wire is the first thing to try. If this does not work look at the drum on the cartridge. I noticed streaks on mine. The streaks lined up with the streaks on the printed paper. I took off the wiper blade which resulted in a mess of spilled toner. (I thought I was being careful and shook the toner away form the drum but it did not shake away. What I sas was a rotary stiring/distibutor rake with lumps of toner in the rake. I cleaned the wiper blade repaceand it still streaked. I noticed that shaking the cartridge and turning the driver gear that turns the rest of the gears with a large flat screwdriver helped some. (note turn it clockwise only because I turned it backwards on a xerox drum broke a flap). Seeing the inprovement I filed a driver rod and turned the gears at about 2 rps / 120 rpm for about 5 min and the drum had a even coat of toner and no more streaks when using it. ( PS reset your toner left clock.)
If anyone find a website that shows the proper names of the parts and/or how these parts work please add the website.

I have a konica minolta c250i, the magenta is not printing on the paper, it print out as yellow. other colors are perfectly ok

There are several reasons why your Konica Minolta C250i printer may be printing magenta as yellow. Here are some troubleshooting steps you can try:

Check the magenta toner cartridge: Make sure that the magenta toner cartridge is properly installed and has enough toner. If the toner cartridge is low or empty, replace it with a new one.
Clean the printer heads: Use the printer's cleaning function to clean the printer heads. This can help remove any clogs or buildup that may be preventing the magenta ink from flowing properly.
Check the printer settings: Check the printer settings to make sure that the correct paper type and color settings are selected. If the printer is set to print in grayscale or black and white mode, it may not use the magenta ink.
Perform a firmware update: Make sure that your printer has the latest firmware installed. Sometimes firmware updates can fix issues with printing quality.
Contact Konica Minolta support: If none of the above steps solve the issue, you may need to contact Konica Minolta support for further assistance. They may be able to diagnose the issue remotely or send a technician to your location.

I hope these steps help you resolve the issue.

Samsung 410 printer is printing pink streaks along the edges of the paper. The magenta cartridge isn't leaking and the reclamation cartridge is recently changed. Any ideas anyone?

Try the magenta drum. Is the drum scraper clean?

Uneven color printing...magenta only on sides of photo...not in the middle

Definitely a faulty cartridge. It is probably a build up of toner on the doctor blade or a deformed doctor blade.

My HP 4700d is printing magenta streaks.

Run a PQ test. On the control panel, go to diagnostics and then find the PQ test. This will print a quality test that will reveal if you have a bad cartridge, which is the most likely cause of magenta streaks.

I have a HP laser 2600n and it is streaking magenta horizontally.

Sounds like the red cartridge was removed or tilted and leaked toner on the drum. Just do a self clean and it will clear up. It in the maintenance menu.

Horz. streak approx.3/4 down on each page I print

Sounds like some of the magenta toner is left behind on the drum. The only way to fix it is to get a new cartridge.

There is not clean cartrige button.
If you want you can try to remove the cartridge and clean it with a paper towel, and see if that helps get you to 300 more sheets, if not I would replace it.

CLP-500 vertical streaks & a horizontal line with blotches appearing randomly

I've refilled the toner cartridges a few times now and never had a problem with vertical streaks until recently. I refilled both the cyan and magenta and when I ran the test page I had dark vertical streaks on both sides. I fiddled around cleaning things, running cleaning paper through, changing reset resistors but to no avail so eventually decided to buy a replacement refurbished cyan cartridge since the streaks looked mainly blue and bingo... well almost now I just have very light magenta streaks. The issue is obvious when I compared the old and new cartridge, the replacement toner is a much duller cyan and is of the wrong consistency since once it's been in the printer everything gets covered in it which is why I think it causes the banding to occur. I'm just trying to work out now whether to try refilling the magenta again (v. messy) or just go for another refurbished cartridge (£34).

Oki C5800 prints magenta streaks

Streaks can be caused by a number of things
The fuser
The ETB
The toner cartridge
The firmware
The printer needs a cleaning.
The slot in the printer.
Incorrect Media.

Try cleaning the printer, use a lint-free cloth for the ETB, DO NOT touch the belt with your fingers, the oil from fingers will often make things worse.
Always use a lint-free cloth, if you ever encounter dirt inside the printer, dampen the cloth.

Calibrate the printer.
From the printer's control panel menu
Configure Device-> Print Quality-> Calibrate now.
(Press the Checkmark key to advance through menus)
