Question about Brother MFC-9420CN All-In-One Laser Printer

1 Answer

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.

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.

A 1/4 inch stripe of magenta ink runs down the side of all pages printed.


Hi ,
Dirty print out is mostly due to cartridge related issues. In this case it seems that magenta is the issue. Take out the cartridge and clean its drum/ (green roller) with a dry, soft, lint-free cloth. The drum is located under a cover. Checkout for any spilled toner inside the printer and clean it also. Print a few pages so that the parts get further cleaned. I think, this would solve the issue.

Moreover, streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located just behind the green drum inside the cartridge. Try cleaning it or replacing the Magenta Cartridge. If required, get the PCR Roller changed by a professional.

Let me know if any further clarification is required.
Hope it helps! Good Luck!

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.

Each color has its own laser. Use the cleaning wand in the front door to clean the lens covers for each color. You will need to remove the waste toner cartridge in front of the the slots to do this. If that does not cure the problem, you will need to replace the developer housings for the colors that are streaking.

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)
