To clear this error, please follow the steps listed below:
Please verify that you have installed both a toner cartridge and a drum unit in the machine. If you have not installed a drum unit or have installed the drum unit improperly, then your Brother machine may produce this error message.

Pull the paper tray completely out of the machine.
Pull the jammed paper out of the paper tray opening.
Open the front cover.

Make a test copy. If the machine jams again, use new paper from a fresh, unopened ream of paper. If the machine still jams, contact Brother Customer Service.
