A variable cut sheet stacker has an internal stacking volume that is readily adjusted (in length, width and height) for a large variety of form sizes and thicknesses. First and second side members are spaced from each other horizontally and the positions between them can be adjusted, typically uniformly moved with respect to a central support. An inlet and support is provided in an inlet for the stacker, having a ramp, and an outlet end guide is adjustable with respect to the inlet end support. A top conveyor conveys cut sheets past the inlet support toward the outlet end guide in a first direction, and a bottom support is vertically spaced in an adjustable manner from the top conveyor for supporting cut sheets. The open interior volume defined by these elements is substantially a rectangular prism. The top conveyor includes a frame that is pivotable about a horizontal axis perpendicular to the first direction to move between a conveyance position and an adjustment-facilitating position. An eject device, in the form of a substantially-vertical paddle, mounted with each side member, is provided for movement with respect to the side members in the first direction to eject a stack of forms and then automatically stop.
