Abstract
In one example, a media feed system includes a pick arm that is adjustable at a pivot and operable to maintain a distance between a pick roller and a separation wall as the pick arm changes orientation. In another example, a media feed system may include a pick arm, a pick roller coupled to the pick arm, a pivot coupled to the pick arm, and a plate coupled to the pivot via a pin and slot interface. In that example, a slot of the pin and slot interface is to adjust position of the pivot and adjust orientation of the pick arm.
Claims9
A tray assembly comprising:
- a separation wall;
- a rigid pick arm having a pivot end with a pivot position and having a free end to position over a media;
- a pick roller coupled to the free end of the pick arm;
- a second arm having a first end pivotally coupled at the pivot position to the pivot end of the pick arm, and having a second end coupled to a pin;
- and
- a first separation roller having a position and a variable feed angle determined with respect to a position of a second separation roller,
- wherein the pick arm is adjustable at the pivot position, and operable to maintain a distance between the pick roller and the separation wall as the pick arm changes orientation, and
- wherein the variable feed angle is dependent on stack height of the media.
A method of operating a media feed system comprising:
- providing the media feed system including;
- a rigid pick arm having a pivot end with a pivot position and having a free end to position over a media;
- a pick roller coupled to the free end of the pick arm;
- a second arm having a first end pivotally coupled at the pivot position to the pivot end of the pick arm, and having a second end coupled to a pin;
- and
- a motor coupled to transmission systems to allow the motor to drive the pick roller and a separation roller;
- adjusting a first position of the pivot position of the pick arm to maintain the pick roller at a substantially constant distance from an angled separation wall;
- and
- adjusting a second position of a separation roller based on the first position of the pick roller,
- wherein the adjusting the second position of the separation roller establishes a variable feed angle of the separation roller relative to an opposing separation roller, and the variable feed angle is based on a stack height of the media.
