Claim 0:
1. A method, comprising:
repeatedly rotating an abutment surface of a pick arm lever forward and backward against an elected item of media in a clockwise and anticlockwise motion about an axis of rotation, wherein the pick arm lever is affixed to a carrier and the carrier rotates and performs rotational motion about the axis of rotation;
inducing motion of a first end of the pick arm lever based on the repeatedly rotating against the elected item of media;
separating the elected item of media by activating a vacuum source situated on the first end of the pick arm lever;
terminating the vacuum source releasing the elected item of media to rollers;
rotating the rollers in opposite directions and a different speeds, wherein the rollers comprise an upper nip roller and a lower nip roller, and wherein the lower nip roller is a partial truncated roller that is not a whole roller, wherein rotating the rollers further includes rotating the upper nip roller having a first diameter in clockwise direction at a first speed of rotation while rotating the lower nip roller with a second diameter in an anticlockwise direction at a second speed of rotation, wherein the first speed of rotation is different from the second speed of rotation, and wherein the first diameter is different from the second diameter, and wherein the rollers rotate at different speeds and have different diameters but the rollers have a same surface speed ensuring the rollers close at different places on each rotation to avoid undue wear in any given location.
