Patent ID: 8123212

Claim:
A method for adjusting media position for media to be fed in an image forming device, comprising: determining a media type for a stack of media sheets on a raisable lift plate; when the media type determined is a first media type: driving a motor in a first direction to drive a pick mechanism for feeding media in a media process direction from the stack of media sheets such that as media is fed the height of the pick mechanism decreases; determining if the height of the pick mechanism has fallen below a predetermined level based on whether a sensor adjacent to the pick mechanism has changed from a first state to a second state as a result of the decrease in height of the pick mechanism; and when the height of the pick mechanism falls below the predetermined level, driving the motor a first predetermined amount of rotation in a second direction opposite the first direction to raise the lift plate in order to raise the pick mechanism to a first desired pick height; and when the media type determined is a second media type: driving the motor in the first direction to drive the pick mechanism for feeding media in the media process direction from the stack of media sheets such that as media is fed the height of the pick mechanism decreases; determining at least one of a number of media fed and an amount of rotation of the motor in the first direction; and when the at least one of the number of media fed and the amount of rotation of the motor in the first direction exceeds a predetermined threshold, driving the motor a second predetermined amount of rotation in the second direction to raise the lift plate in order to raise the pick mechanism to a second desired pick height different from the first desired pick height.
