The paper jam you had probably lifted the long, thin, plastic encoder strip in the pathway out of its slot, giving the false indication of a paper jam. In order to put it back in its place, please carry out the following steps:

1) Lift the cover and remove the two plastic panels covering wires. Mark down the position of cables, then remove them, and remove the now-freed top scanner section entirely.

2) Remove the screws from the top plastic shell. There's two in the back and four in the front. There's also two plastic tabs in the front that must be bent aside before you can remove the top shell.

3) Gently put the encoder strip back in its plastic guide, and check if you are able to get your printer to work all right thereafter.

If you are not comfortable carrying out the steps, I would strongly suggest you to have it repaired by your local Brother service center, without causing further complications.

hi Eagon, i realized that as soon as i sent the last reply. i also didn't realise that you had sent me the first instructions (guess i read too quickly and didn't pay enough attention) anyhow i am comfortable with taking the panels off however can you just clarify step 1 removing the two plastic panels. also i am happy to hit the accept answer button on doing so am i able to still ask for any more information on this one topic/question? thank you vicky
Sure Vicky, to clarify step 1, There should be plastic wire covers inside the printer that will need to be removed and the wires adjusted to remove the top scanner piece. This is done to make it easier to reach the plastic encoder strip.

Ultimately, the paper jam you had probably lifted the long, thin, plastic encoder strip out of its slot. It is making the printer think paper is still jammed. Try gently pushing the strip back into the slot. You might have to use a screwdriver or other thin instrument to get to the strip.

Yes, you are able to request more information if needed. You can hit the accept button once you are satisfied with the help or answer given. Good luck!

hi we can only locate one panel with wires under it is there a possibility of a snap short diagram or picture for us to clearly identify what panels. thanks
unfortunately no diagrams or pictures are available. Without being able to look at that specific printer, there may very well be a single panel that is removed. However, there may be an alternative solution for you without having to remove the piece.

1. Turn off the power
2. Put your fingers inside the gap next to the print head and you will feel a thin cable that runs horizontally parallel to the hole.
3. Push the cable up so it is flat against the plastic molding and pull it toward the back of the printer.
4. Move the cable forward so that it relocates back into the slot.
5. Turn the printer back on and check that the error code has gone.

This may take several attempts to get it back into the correct slot, shouldn't take more than 5/10 minutes once you figure out which bits go where. Hope this helps.

hi Eagon

thanks that worked and the printer head now is on the left hand side of the printer where it should be and it moves freely however it is still saying unable to print 50

Is the clear plastic guide now fitting into the encoder strip? If, not use tweezers and place the guide back into the encoder strip. Also please try disconnecting the power for a few minutes.

Unfortunately, after researching further this is the only solution available for this error code. You may have to contact a Brother repair agent since it could be another broken or faulty part.

Hope I've been able to help.
