SHEET STACKING APPARATUS, METHOD FOR CONTROLLING SHEET STACKING APPARATUS, AND STORAGE MEDIUM

摘要

A sheet stacking apparatus includes a lowering control unit, a determination unit, and a control unit. The lowering control unit lowers a sheet stacking unit according to a stacked sheet amount. The determination unit determines whether the sheet stacking unit cannot be lowered by the lowering control unit. The control unit performs control to store a position of the sheet stacking unit and stop stacking of the sheet when the determination unit determines that the sheet stacking unit cannot be lowered while the sheet is being stacked on the sheet stacking unit. The control unit performs control to raise the sheet stacking unit when the stacked sheet is removed in a state where the stacking of the sheet on the sheet stacking unit is stopped, stack the sheet on the raised sheet stacking unit, and stop lowering of the sheet stacking unit based on the stored position.
