Claim 6:
7. A control method for a medium conveying apparatus including a pick roller feeding a medium, a separation roller on a downstream side of the pick roller in a conveying direction of the medium, an arrival detection sensor on a downstream side of the separation roller in the conveying direction and detecting arrival of the medium, and a lift sensor detecting a lift of the medium between an upstream side of a roller nip of the pick roller and a downstream side of a roller nip of the separation roller in the conveying direction, the control method comprising:
determining that the medium is a bound medium when a lift of a medium is detected by the lift sensor in a first predetermined period after detection of a front edge of a medium in a conveying direction by the arrival detection sensor; and
executing abnormality processing when the medium is determined to be a bound medium.
