Inventor: TSURU KENJI
IPC: G03G15/20
Filed: 2012-04-10
Abstract: PROBLEM TO BE SOLVED: To improve a printing performance by performing an output control of separating wind by adequately grasping the behavior of a sheet due to the separating wind.SOLUTION: When a displacement detection part 51 detects a displacement of a separation pawl 42, a fixing control part controls a shutter drive part based on the displacement of this detected separation pawl 42 so that the output control of the separation wind is performed. Since the separation pawl 42 is applied with a force from a sheet P receiving the separation wind, it can be presumed whether or not the behavior of the sheet P is proper by monitoring the replacement of the separation pawl 42. Further, though there is the case where the behavior of the sheet P depends on the type of sheet P, since an effect of the separation wind is dominant, the output of the separation wind is controlled based on the displacement of the separation pawl 42, thereby the behavior of the sheet P to be transported can be prevented from falling into an inadequate state.
