I have a Brother MFC-3360C printer and have an error. Clean Unable 51

Error 51 normally indicates a paper jam or a sensor problem. Check the paper path and the printer head movement zones (far left and right) for any foreign objects (even small pieces of paper). If there has been a paper jam, was the paper forcibly removed? If so, possibly one of the sensors has been knocked out of position or damaged. Dust, dirt, grease or spilled ink may also be contaminating a sensor. This is maybe one of the most elusive problems to solve..!

Unable to print or copy, see troubleshooting 51

The error means you have a paper jam or one of the sensors is incorrectly reading a paper jam. Unplug the unit and check all areas for a jam. Remove the back Jam Clear Cover and check inside there. Remove the Paper Tray and check that area and check if the PE actuator is in place behind the paper tray. Lift the scanner flatbed unit and check inside the print carriage area. Look for scraps of paper at the sides of the platen. These scraps that may be soaked with ink and difficult to see. You may need to move the print head to see both sides.

If the PE actuator is missing, contact Brother for a replacement. Put in the replacement if needed.

Close the scanner unit, replace the clear jam cover (put it on correctly) and replace the paper tray. Plug in and turn on the printer and see if the message clears. If it doesn't clear, access the Ink or Ink Management menu (either directly by a single key or through the menus). Do a test print for Print Quality (Color). If the quality is good, press 1, the up arrow or + key to select Yes. Then press the Stop/Exit button. If the print quality is poor, clean the print head.

If the jam message occurs again, check for more scraps of paper inside the unit as above. Make sure your paper meets the specifications for the printer and isn't getting excessively humid. (Paper will pick up moisture from the atmosphere so keep only the needed amount in open reams or the paper tray.) Fan the paper in the tray and then return it to the paper tray. Make sure the paper is flat in the tray and that the guides are just touching the edge of the paper.

If it still doesn't clear, the unit needs service.

I hope this helps.

I cannot print or copy . i see error 51

Error 51 is a paper jam code. Remove the paper tray in the front and the jam clear cover in the back (the light gray plastic piece in the center of the rear of the printer) and pull out any paper you can see.

Once you've removed the paper, the jam code should clear on the display, but if it doesn't, try resetting the machine. If the jam code is still there, that means there is still paper somewhere inside the machine. Check again to make sure you didn't miss any, and also lift the scanner bed to see if you can see any paper under there. (To lift the scanner, lift up with the tabs on either side until the scanner locks into place.)

Unable to clean 51

If there is no jam it is generally a mechanical issue such as...

1. The planetary arm assembly not engaged correctly
2. Ink cartridge/purge switch harness not connected correctly
3. Purge cam switch broken
4. Gear(s) on maintenance unit broken
5. Paper feed motor broken
6. Main PCB defective

I find that if there was a paper jam, and the user pulled the paper out, option 4 is most likely. It is the smallest of cracks but ruins everything!

Do the following:

If the error message continues, disconnect the machine from
the power for several minutes and then reconnect it.
