Introduction

I took it apart and reassembled it several times before I found the very simple fix - which takes less than a minute!

What you need

Step 1

              take off back cover
  • Stick your printer on a table and get to the back of it. Then remove the white flap from its hinges. you may need to bend the plastic a little for the plastic studs to pop out.

Step 2

              remove inside cover
  • With the white flap off, unscrew the single screw and pry out this black cover.
  • Once out this will allow you to un-clip and remove the paper guide from the printer.( pinch the two green levers)

Step 3

              remove photocell shroud
  • You now have access to the black shroud that covers the photocell emitter & receiver. Pry it upwards and off with a small opening tool.
  • Inspect the paperguide: a small black spring loaded lever in the middle should move the “blocking piece” freely up and down.
  • Reassemble in reverse order, ensuring the blocking piece moves freely between the photocell emitter & receiver.

To reassemble your device, follow these instructions in reverse order. This may be the fix you are looking for or perhaps your printer has a different issue. Clearly a slight knock to this plastic shroud meant the photocells were no longer aligned and this printer was unusable…until now.

OMG THANK YOU SO MUCH! I have spent untold hours on the phone with Brother — and finally ran across your post. Worked in 2 minutes. THANKS!

It’s not explicitly clear here - but what you are doing is removing and LEAVING OUT the black U shaped shroud from the device.

Wow, you nailed it! As soon as I read your observation that the machine always stopped at exactly the same spot - despite there being no paper jam - my mood changed. It worked like a charm. Thanks for sharing the experience with others.

Thank you! Totally worked. To add to post we removed the shroud and left it off.
