Abstract
A sheet sorting device includes a plurality of trays, a tray shifter, a tray stop position detector, and circuitry. The plurality of trays is disposed in multiple stages in a vertical direction and configured to stack a sheet. The tray shifter is configured to move the plurality of trays separately in a tray shift direction. The tray stop position detector is configured to detect stop positions of the plurality of trays separately. The circuitry is configured to cause the tray shifter to move the plurality of trays to home positions in an initial operation, at least one tray having a home position opposite to a home position of another tray in the tray shift direction. The circuitry is configured to, while moving the plurality of trays at a same time in the initial operation, cause the tray shifter to move the trays in directions opposite to each other.
