Abstract
A sheet feeder includes a lift table, a first sheet-side restricting member, a second sheet-side restricting member, a suction conveyor, a rear-end restricting member, an upper distance-measuring sensor, a lower distance-measuring sensor, and processing circuitry. The first sheet-side restricting member and the second sheet-side restricting member restrict first ends and second ends opposite to the first ends, respectively, of sheets. The suction conveyor sucks and conveys a sheet floated. The rear-end restricting member restricts the sheets from moving in a longitudinal direction of the sheets. The upper distance-measuring sensor and the lower distance-measuring sensor measure a first distance and a second distance, respectively, to the first sheet-side restricting member or the second sheet-side restricting member. The processing circuitry compares measurement results of the first distance and the second distance to determine whether a distance between the first sheet-side restricting member and the second sheet-side restricting member is adequate.
