Setting Up the Stacker [fi-8190/fi-8170/fi-8150/fi-8150U]
Documents loaded in the ADF paper chute (feeder) are ejected onto the stacker one by one during scanning.
When scanning a relatively long document such as an A4 size document, using the stacker, stacker extensions 1 and 2, and the stopper as described below will keep the documents straight and feed them smoothly.
