My Brother printer displays a persistent 'Paper Jam' error even after removing any jammed paper. How do I clear it?

First, power cycle the printer – turn it off, unplug it from the wall for at least 60 seconds, then plug it back in and turn it on. If the error persists, open all access doors (paper trays, rear cover, etc.) while the printer is on. This signals to the printer that the doors are open and may reset the sensors. Check for small paper scraps or obstructions in the paper path using a flashlight. Finally, perform a factory reset (consult your printer's manual for instructions, as the process varies by model) as a last resort.
