Abstract: A system for automatically releasing selected plural sheet feeding nip sets spaced along a print media sheet feeding path of a printer, wherein the idler rollers are rotatably mounted on common idler shafts and a selectable partial rotation system driven by a single low cost motor is flexibly connected to those plural idler shafts to partially rotate eccentric lift cams on each idler shaft into the underlying surface as to lift the idler shaft and thereby move the idler rollers away from their normally mating sheet feed rollers to release all the sheet feeding nips, enabling sheet deskew, inversion, acceleration, deceleration, or sheet jam clearance in that selected area of the sheet feeding path.

Abstract: As the individual pages of a book having a gutter and outside edge margins and being held at least partially open are being automatically sequentially turned over, in coordination therewith a flattening force is applied to the unimaged gutter margin areas of the book for flattening the pages after they have been at least substantially turned over, and unimaged outside edge margins of the book are clamped by automatic clamping members in coordination therewith, for appropriate page viewing and/or imaging. The flattening force may be applied with a V shaped reciprocally movable member, which may also be partially self-centering in the book gutter, and may also open to push outwardly on the then-open pages, as applied.

Abstract: The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.
