Printer stops partway through printing. Indicates a paper jam.

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.
