ABSTRACT:
An improved printer paper stack-handling device is described. In its preferred embodiment, the stack-handling device includes a pivot member with a downwardly inclining paper top-of-stack contact surface. The device also includes a force mechanism, e.g. a leaf spring, to pivot the member into contact with the top sheet of a paper stack. The spring and the pivot member's inclined contact surface produce a variable top sheet bias for corresponding variable paper stack heights, to properly laterally align the top sheet against a fixed, opposing guide rail, for feeding to a printer input port.
