Print-medium post-treatment apparatus and control method thereof

摘要

A print-medium post-treatment apparatus and a control method thereof, to increase the number of print media stacked on a bookbinding stack tray (13) by controlling operation of a conveyor belt. The print-medium post-treatment apparatus includes a bookbinding stack tray including a tray sensor (51,52,53) to sense a print medium and a conveyor belt to move the print medium, and a controller to move the print medium in a given discharge direction by operating the conveyor belt in a first direction if the tray sensor senses the print medium moved onto the bookbinding stack tray and to move the print medium in an opposite direction of the discharge direction by operating the conveyor belt in a second direction so as to reduce a distance between a previously discharged print medium and a subsequently discharged print medium.
