Brother MFC-440CN unable to print after paper jam. while printing. I have removed the paper jam and I get a message stating "unable to print 50." I have asked for a description of parts I'm supposed to work with in order to fix my problem and I am not getting an answer. So far I have not gotten the correct help and am very frustated and am ready to give up.

SOURCE: I had a paper jam

i saw a solution from mix-it-up, he said machine error 50 means this plastic strip that runs under the printer head is not straight anymore. he said the printer head uses the strip as a guide to determine its position along the printer head track. it's possible that it got caught underneath the printer head during the paper jam. i have a picture here of the strip http://img168.imageshack.us/my.php?image=encoderstripdh1.jpg. and i made a pdf slideshow of how i dissembled the top of my mfc-420cn. http://www.sendspace.com/file/ktvhfe. you only have to follow my slideshow up to where the printer body cover is removed until u see the plastic strip. just move it around until it's no longer bumped or pushed by other moving parts. the design should be similar to the 440cn.

Confirm Success on a 440CN

1) Remove Plastic wire covers from inside printers, and release plastic stay on lower edge, tilt cover to 90 Degrees
2) make a note of where each connector goes
3) release the Ribbon and 3 Multicore cables, removing grounding screw, then remove scanner module by sliding it off the hinges at 90 degrees.
4) Remove Three Front Panel Screws, carefully leaver front panel upwards releasing front side clips.
5) Remove front panel by disconnecting ribbon and wireing on both sides.
6) Remove 6 Screws (2 on back, three at front and one middle right
7) Carefully remove speaker cable (Red Connector) and lift up plastic casing, leaving printer uncovered.
8) Re-Seat Encoder Strip into guide. (The Transparent strip)
9) Re-assemble in reverse and Hey Presto.

All Cured. Hopefully!

congrats! You just bought yourself a brand new printer! I just phoned the company and apparently if you have a teeny tiny paper jam and a Unable to print 50 pops up ... you just bought yourself a new machine, that particular message means your machine was damaged thru the course of your paper jam. The average cost an hour to fix it is $85 so its better to just buy a new one.. What a piece of ****. :-(
