Method for Applying Pick Retry Using a Modified Pick Roller Force to Reduce Likelihood of Failure to Pick Top Sheet From Stack

A method for applying a pick retry using an increased pick roller normal force, comprising:

• operating an actuator in a first duty cycle to create a force to rotate a cam connected to a pick roller, the rotation of the cam causing the pick roller to move down into contact with a media stack and to impose a first intermittent normal force on the media stack ordinarily sufficient to pick and feed a top sheet from the media stack to a media path;
• sensing whether or not the sheet arrives in the media path within a predetermined time period after start of said operating the actuator in the first duty cycle;
• and
• retrying the actuator in a second duty cycle larger than the first duty cycle to cause the pick roller to move down into contact with the media stack and to impose a second intermittent normal force on the media stack larger than the first intermittent normal force in response to not sensing the arrival of the sheet in the media path.
