Patent ID: 7699305

Claim:
A method of controlling movement of a media sheet within an image forming device comprising: driving a pick mechanism to rotate a pick member in contact with the media sheet to move the media sheet from an input area; receiving a first signal indicating rotation of the pick member; receiving a second signal from an encoder in contact with the media sheet and indicating movement of the media sheet in a first direction and in a second direction; filtering a combination of the first and second signals to generate one or more filtered feedback signals; and controlling the movement of the media sheet by driving the pick mechanism based on the one or more filtered feedback signals and a position of a toner image on a transport belt to move the media sheet with the pick mechanism to a transfer area where the toner image is placed on the media sheet, wherein the one or more filtered feedback signals comprises a velocity feedback signals, and wherein controlling the movement of the media sheet comprises driving the pick mechanism based on the velocity feedback signal to control a rotational velocity of the pick member, and wherein the one or more filtered feedback signals comprises a position feedback signal, and wherein controlling the movement of the media sheet comprises driving the pick mechanism based on the position feedback signal and the velocity feedback signal to control a rotational velocity of the pick member.
