DO NOT leave thick documents on the scanner glass. If you do this, the ADF may jam.
DO NOT use paper that is curled, wrinkled, folded, ripped, stapled, paper-clipped, pasted or taped.
DO NOT use cardboard, newspaper or fabric.
To avoid damaging your machine while using the ADF, DO NOT pull on the document while it is feeding.
Fan the pages well.
Place your document face up, top edge first in the ADF until the LCD display message changes and you feel it touch the feed rollers.
