20090001649SHEET STACKING APPARATUS AND METHOD OF CONTROLLING THE SHEET STACKING APPARATUS - A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while making efficient use of space therein to realizing compactness of the apparatus. Stacker trays that are driven by respective tray lift motors perform a lifting/lowering operation to have sheets stacked thereon. Selection is made according to the size of sheets between a first stacking mode for stacking sheets having a size not larger than a predetermined size on one of the stacker trays and a second stacking mode for stacking sheets having a size larger than the predetermined size in a state extending on the stacker trays. When it is determined that one of the stacker trays is faulty, execution of the second stacking mode is inhibited, and execution of the first stacking mode using the other stacker tray is permitted.01-01-2009
20090001650SHEET STACKING APPARATUS AND METHOD OF CONTROLLING THE SHEET STACKING APPARATUS - A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while efficiently using space therein to thereby realize compactness thereof, and maintaining a high availability. Stacker trays for stacking sheets discharged from an image forming apparatus can be separately removed. It is detected whether any of the stacker trays is removed. When large-size sheets are stacked, a stacker control section causes the stacker trays to operate as one tray to stack the sheets in a state extending on the stacker trays, whereas when small-size sheets are stacked, the section causes one of the stacker trays to stack the sheets. Further, when one stacker tray is removed to make it impossible to stack the large-size sheets, the section causes a display section to display a guide message advising setting of the removed stacker tray.01-01-2009
