Abstract
A sheet feeder is provided. The sheet feeder includes a roller to feed a sheet, a motor to rotate the roller, and a motor controller to control rotation of the motor by a feedback control. The motor controller detects a condition of the sheet based on a value acquired in the feedback control at the time a load is applied from the sheet to the roller, while performing a stop control to stop the roller at a designated stop position. The stop control is performed after the motor is rotated in a direction opposite to a direction of feed of the sheet.
