Thank you Jackboy. The solution would have help but I could not locate the micro switch to press manually. I remember that while I was trying to remove the paper I opened part of the printer to remove the paper manually, there was a small spring that remove which I can not locate where it is from.

This suggests that the micro switch that controls the opening/closing signal to that 'door' is malfunctioning. Open the door,find the switch and manually press it right in then whilst holding it in - try to operate the machine.

If you turn the printer off and then back on with a paper jam in it you will get this error message instead of a paper jam message. To clear the paper jam from the back of the printer read the instructions from here: http://welcome.solutions.brother.com/BSC/public/us/us/en/faq/faq/000000/000600/000096/faq000696_001.html?reg=us&c=us&lang=en&prod=mfc7420_all&Cat=11

Printer will not print after paper jam. after removing the jam the ready light comes on and when we try to print again the screen shows it is preparing to print but it does not print

This error message is displayed by the printer when paper is jammed in one or more locations. In such a case, users are recommended to remove the jammed paper from the specified location. The entire paper path must be checked for any pieces of paper. To stop the message, open and close the top most cover of the printer. Lastly, verify the flags and the sensors. If the problem persists, the cause of the error message could be a broken sensor or sensor lever.

Had paper jammed - removed jammed paper - but nerror light still on

Before you can clear a "PAPER JAM" or "PRINTER JAM" error, you must locate where in the unit the paper is jammed.

Paper is jammed inside the paper tray:

Pull out the jammed paper to remove it.

Reload the paper in the paper tray.
Reinstall the paper tray.

Paper is jammed inside the machine:

Remove the jam clear cover on the back of the unit. Pull the jammed paper out of the machine.

Re-insert the jam clear cover.
If you can not pull out the jammed paper, lift the scanner cover from the right-hand side of the machine until it locks securely into the open position.
Remove the jammed paper.
Check the print head's position. In the example photo the print head is positioned at the left hand side of the platen area.
Gently move the print head to the center.

Note Be careful to not force the print head to move.
If the print head is positioned at the far right hand side, you cannot move it. Please contact Brother Customer Service from "Contact Us".

Note Use a flashlight if necessary to check thoroughly.

Reconnect the power cord and telephone line.

Note To prevent paper jams, do not put multiple kinds of paper in the paper tray at the same time.

Paper jam while printing on BROTHER MFC-290C all-in-one

hey

try this

Turn off the printer.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Also open the back cover of the printer if this model has one.
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
see alternative if the problem is still not solved.

alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.
