Message unable to print 50

Error code 36 is generally because of a paper jam that was not cleared. Remove the rear jam cover (the plastic cover in the back center of the machine)and the paper tray and check for any pieces of paper. Sometimes just a scrap will remain, but it's enough to cause the machine to not work.

Once you've replaced the covers, if the jam code does not reset, turn the machine off and then back on.

This error is usually caused by the Carriage Encoder Strip being dislodged from
the sensor mounted on the Print Head/Carriage Assembly.

Unfortunately, you will need to remove the scanner assembly, and top cover assembly to check to see if the encoder strip has come out of the printhead assembly.

I have the same problem. Most people i asked about it said it is a mechanical problem. It's better to bring it to a brother service center near you.

Same problem with Solution: http://www.fixya.com/support/t211210-brother_mfc845cw

Do the following:

Print Unable
XX
The machine has a mechanical
problem.
—OR—
A foreign objects such as a clip or
ripped paper is in the machine.

Open the scanner cover and remove any foreign
objects inside the machine. ( You might try cleaning the scanner glass.)
If the error message continues, disconnect the machine from
the power for several minutes and then reconnect it.

Try this and let me know what happens. Binary Bob

clean unable, how do I fix it?

I got one of these from a friend who couldn't get theirs to work. I got an error message that alternated between "print unable 50" and "print unable 30". I called Brother and checked on-line for a solution. Nothing helpful. So I took it apart, (after unplugging it from the power outlet), just a few screws and snap locks really, wasn't too hard. When I got the black case, the body of the MFC, off I found a clear guide ribbon that rests in a track on the back of the print head resting on top of the print-head assembly. I put the ribbon back in the track and reassembled the MFC. I think a bad paper jam pushed the ribbon out of the guide track on the print head . All the errors are gone. There are no instructions for the dis-assembly, but its not hard.


The screws, (8-10 screws in all), aren't hard to find, just the two screws hidden under the open hinge as shown here. You have to unplug some circuit connectors too. This method is best done by someone comfortable with taking the MFC apart.

Or if you have small hands, you could probably get it to catch with your fingers in the opening for the print head as shown above, but I didn't get it repaired that way. Good luck. Post the results if you try to fix it.

my brother mfc-440cn printer says, "unable to print 51" on the screeen after if off (which it woudn't let me do. I had to unplug it. It just won't work.

I can't help directly but if you go here to the (Australian) support site

http://www.brother.com.au/customersupport/customersupport.asp

you may find your answer.

Note You may need to contact them direct to get your answer.

Good luck.

...and 50? Is it toggling between those two error codes?

Anyway, see here what to do:
