Cannot find jammed paper. How do I remove print head of Brother MFC-620CN? Removing back cover does not reveal any jammed paper.

To remove the head and clean would require a near dis assembly of printer.

in short, open the lid as if to replace ink, unclip the bottom of the lid leg and swing open.leave ink in.

remove 4 screws and remove plastic clips to wires. disconnect wires there are 4 or 5 in total. now carefully unhook the lid from main unit, take your time.

after separating 2 parts.

unclip plastic cover on head, remove print head cable wire from head, unclip silver clip that hold ink hoses,
undo top (in relation to head) slide bar, carefully remove head..
lift from no bar side first.

Hi,

U can do the below steps but it will best if u call an engineer to the job:-
You see the access door in the back where you would remove a jam? That is the back side of the fuser unit. You'll have to take the scanner top off and the other back panels to unplug the scanner and controls....the sides, the laser assembly, other things... and finally you'll have to disassemble the fuser in order to remove it and get access to the sensor arm.
Just look and remember where all the parts go

You can't just remove the broken sensor arm. The printer needs it to know where the paper is during its travel. It will need to be fixed or 'engineered' back to a functioning form.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Open the front cover and pull the drum and toner cartridge out. If there is resistance, pop the scanner cover up and pull the paper tray out as well. Carefully remove the paper you find and reassemble.

Open up amd release blue stay at bottom by pressing edges inward and pulling slightly forward. Remove the 4 screws, 2 small plastic covers and the earth screw. Pull out the ribbon connector near the USB plug. Unplug the 2 white and one red connectors, noting how the cables fit in. Fully open the lid and pop the scanner part off. Remove all the ink cartridges. Now using a flat screwdriver unclip the top of the base all the way round and lift off. The print head is now accessible. Rotate the white paper feed cogs to release the print head. Slide it all the way to the right and remove it by tilting the back edge upwards. You mow have access to the print head!!!!
Print head should be slid LEFT when viewed from the front

You may not have of piece of paper jammed in the unit this would be very visible even if the paper had rolled up to the printer head itself. even then most of the time it will just eject it because of interference.

there can be any number of problems that can cause this.

1. the tray has not been properly adjusted to the paper you are using
2. the tray itself is overloaded with paper
3. the tray is not full enough to pick up paper
4. the tray will not lift to allow the paper to be picked up
5. the rollers have become worn,dirty, or weak
these are just a few problems that can cause your printer to say that there is a paper jam. if yours has been in use like mine for several years and used repeatedly daily. yes, i own a brother printer too and even though it still works great most days I get this same message all the time just because it wont properly lift or shuffle the paper.

I normally just pull the paper tray turn the paper over re stack and place back in readjust the tray so the paper fits properly and it will work fine in most cases at least until it gets low. also once every 3 months i take a can of air to it just to blow out dust, dirt and contaminants this is probably not a problem for you but still a good idea. I hope this has been helpful please let me know if I can be of further assistance
