Remove all originals remaining in the input tray.
Pull the lever to open the scanner cover.
Carefully remove any jammed originals.
If you cannot pull originals straight up, carefully pull out any jammed originals from the output slot in the direction of the arrow.
Make sure there is no paper inside the scanner.
Close the scanner cover with both hands.
Before restarting scanning, make sure that the scanner is stationary. If the scanner is not stationary, it could cause the original to jam.
