IMAGE FORMING SYSTEM, AND IMAGE FORMING SYSTEM CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image forming system in which an image forming device is connected to a plurality of paper sheet stacking devices, and occurrence of jamming and stacking-collapse caused by the accumulated curl of output paper sheets stacked through a large amount output operation is prevented. SOLUTION: A sensor to detect the accumulated curl is provided on a paper sheet stacking device, and when the curl exceeds a set value, the continuous output is performed by changing the discharge destination. Alternatively, paper sheets of different kinds such as cardboards capable of keeping flatness are placed on the stacked output paper sheets for continuous output, and the accumulated curl is eliminated by the weight of output paper sheets on the cardboard. Jamming and stacking-collapse can be prevented thereby. COPYRIGHT: (C)2006,JPO&NCIPI
