Brother Printer MFC-J6920DW: Black print head clogged with ink.

Sun, 28 Jun 2020 06:53:18 -0700

This has been a gradual failure to print just the black. I have done 3 cleaning cycles, over multiple days, this worked a little but used quite a bit of ink. Then I used a syringe kit with cleaning fluid and paper towels under the head. Made a bit of a mess and pulled out a bunch of color ink at the same time. That did help, I got back about 90% of the print range. However it quickly failed again to 0%. All I have used in this is Brother Ink.

Can the print head removed more a through manual cleaning? What happens to the ink used in the self cleaning operation?

Brother MFC-240C: MFC-240C does not print - despite fresh cartridges and multiple purge

Fri, 19 Jan 2018 14:32:57 -0700

My Brother MFC-240C prints in black, but in none of the colors. I have already installed new original Brother ink cartridges, and executed multiple Normal/Power Purge runs (using the Maintenance Mode as described in the service manual, chapter 9 / 9-43). The problem persists.

Can anybody help? Has anybody successfully disassembled the printer, and cleaned manually the ink supply tubes and/or the printing head?

Brother Printer MFC-J6920DW: Error: Cannot Initialize 8F

Thu, 08 Dec 2016 10:34:37 -0700

Brand new printer, just arrived today. It says "Cannot Initialize 8F".

After looking around that generally means some kind of jam, but it's new and there is no jam.

When I lift the scanner bed and hold the red "x" on the touchscreen to move the print head to the middle there is the sound of belts slipping and the print head does not move.

Is there a known way to fix this?

Brother MFC-240C: Paper won't feed. White part in back fell off

Wed, 08 Jul 2020 08:21:48 -0700

A small white plastic piece has fallen off in back.

White piece has small crack that seems repairable.

I can't see where it fits back on.

Keep getting "No Paper Feed" message since the paper isn't getting picked up by the rollers.

The printer is trying to feed the paper and when it quits the top page has significant roller marks on it.

Brother MFC-L2740DW: Printer stops partway through printing. Indicates a paper jam.

Wed, 03 Dec 2025 17:22:52 -0700

Hi all,

Perhaps someone here has had the same problem with this model or family of printers and has found a solution.

I’ve cleaned all the rollers that I can find:

1) Pickup rollers in the paper drawer,

2) Under the drum/cartridge,

3) At the back of the printer through the tilting cover,

4) At the final output.

I followed Brother’s advice and used alcohol first but then bought a rubber renew product by MG Chemicals called “Rubber Renue”. The latter took made the rollers fresh-looking again. Be careful that you don’t get it on the plastic parts as it seems to melt them a little. :^)

It still didn’t work so I called Brother and they had me go through some steps to see where in the paper path the problem was happening. To do so, they asked me to open the back door, feed paper into the single sheet feeder, and then press the following key combination to get into a maintenance mode:

Please read the following instructions carefully in order to access the MAINTENANCE menu of your Brother Printer.

1. Please make sure the screen of the printer is on the home screen. If it is not, please press on the Red [X] to return to the home screen.

2. Press on [FAX] - The [Home] Icon will light up.

3. Press and hold the [Home] Icon until the screen changes to a black screen with four rectangles. It will first go back to the Home screen, keep holding it and it will change again.

4. Press and hold the bottom rectangle until a Number Pad appears on the screen.5. On the Number Pad, please enter the following 5 code numbers in order, as quickly as possible: [*] – [2] – [8] – [6] – [4].

6. If the code is entered correctly, the screen should display: MAINTENANCE right above the Number Pad.

7. Now press 77 and press Mono Start.

After about 10 seconds it should print out a diagnostic page. Mine jammed, of course.

In the picture below you can see how far the paper travelled until it jammed in my printer…

Any help with this would be greatly appreciated.
