Abstract: A web printing system automatically detects the location of a wrinkle in a moving web. The web has a plurality of marked reference positions including an inboard position, a center position, and an outboard position. A plurality of contact image sensors detect the reference positions after the web passes through a spreader and an inboard distance and an outboard distance are respectively measured from the center position. If the inboard distance is less than a nominal inboard distance, the wrinkle is identified as inboard of the center position. If the outboard distance is less than a nominal outboard distance, the wrinkle is identified as outboard of the center position. The machine operator is notified of the fault condition and takes action to remedy the situation.

Abstract: Disclosed is a cart having a support surface with a selectively adjustable contour for providing essentially uniform support to a load (e.g., a stack of print media sheets) during receiving and storing modes and for facilitating transfer of the load to another support surface during a transferring mode. The cart can comprise a support surface with alternating fixed and movable sections. In the receiving and storage modes, the movable sections can be top aligned with the fixed sections so that the support surface has an essentially planar contour for providing essentially uniform support. In the transferring mode, the movable sections can be dropped lower so that the support surface has a corrugated contour for facilitating transfer of the load (e.g., using an interdigitation technique). Also disclosed is a printing system sheet stacker incorporating such a cart for receiving, storing and transferring of a sheet stack as well as associated methods.

Abstract: A stacker support with automatic unload function for flexible media includes a first set of ribs and a second of ribs. The stacker support is moved between a first UP position and a second unloading position. In the first UP position and loading positions, the first set of ribs and the second set of ribs are aligned so that their surfaces from a single uniform continuous surface for supporting stack of substrate sheets. In the second unloading position, the top surface of the second set of ribs is caused to move below the top surface of the first set of ribs whereby the top surface of the first set of ribs forms a ribbed surface that supports stacked sheets. The gaps formed thereby permit unloading by a cart having offset ribs.
