Sheet conveying device and image forming apparatus incorporating the sheet conveying device

A sheet conveying device comprising:

• a rotary body configured to convey a sheet along a sheet conveying path, to rotate in the sheet conveying direction, and to move in a width direction of the sheet;
• and a controller configured to,
• receive data from a plurality of detectors configured to sequentially detect the sheet as the sheet travels in the sheet conveying direction along the sheet conveyance path, the plurality of detectors including at least a first detector, a second detector and a third detector,
• perform a primary operation to correct an angle deviation of the sheet and a lateral shift of the sheet based on a result detected by the first detector and the second detector, respectively, the primary operation including instructing one or more drive motors to both (1) rotate the rotary body in the sheet conveying direction before holding the sheet and return to a reference position after holding the sheet and (2) move in the width direction of the sheet before holding the sheet and return to the reference position after holding the sheet, and
• perform a secondary operation to further correct at least one of the angle deviation and the lateral shift based on a result detected by the third detector after the primary operation, the secondary operation including further instructing the one or more drive motors to at one of (1) rotate the rotary body in the sheet conveying direction before holding the sheet and return to the reference position after holding the sheet and (2) move in the width direction before holding the sheet and return to the reference position after holding the sheet.
