Zusammenfassung: | To improve processing efficiency of print jobs as a whole in an image forming device and a sheet post-processing device.SOLUTION: A finisher 500 as a sheet post-processing device of an image forming device 10 includes stacking trays 700, 701 for stacking sheets, a pair of rollers 515, 680 which discharge the sheet to the stacking trays, and a finisher control part 951. The finisher control part determines whether or not a sheet stacking amount satisfies a full stack condition of the stacking trays from contents of a plurality of previously-known unexecuted print jobs, determines an execution order of the print jobs so as to execute the print job which does not satisfy the condition, first with a higher priority, and notifies a CPU circuit part 900 in the image forming device of the execution order to start execution of the print jobs.SELECTED DRAWING: Figure 13
【課題】画像形成装置及びシート後処理装置において、印刷ジョブ全体としての処理効率を向上させる。【解決手段】画像形成装置10のシート後処理装置としてフィニッシャ500が、シートを積載させる積載トレイ700,701と、積載トレイにシートを排出するローラ対515,680と、フィニッシャ制御部951とを備える。フィニッシャ制御部は、予め判明している複数の印刷ジョブの内容から、そのシート積載量が積載トレイの満載条件を満たすか否かを判定し、満たしていない印刷ジョブを優先して先に実行するように、それら印刷ジョブの実行順序を決定し、画像形成装置のCPU回路部900に通知し、印刷ジョブの実行を開始させる。【選択図】図13 |
