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.
