摘要:
When a jam is detected in a post-processing device, a purge controller first makes a conveyance roller group and a reverse roller continue conveyance. The purge controller then sets the conveyance destination of a leading sheet that will first arrive at a branch point after the time of detection of the jam. When a first condition is satisfied the purge controller sets the conveyance destination to a reverse slot, and when a second condition is satisfied the purge controller sets the conveyance destination to an outlet path. The first condition is satisfied when no other sheet is present in the reverse slot at the time of detection of the jam, and the second condition is satisfied when another sheet is present in the reverse slot at the time of detection of the jam.

A sheet conveying device includes: a conveying unit configured to convey a sheet along a conveying path; a switching unit configured to switch a sheet conveying destination; a delivering unit configured to deliver the sheet on the delivery path toward a device at the sheet conveying destination; a reversing unit configured to first convey the sheet from the reversing port toward the outside of the casing to a position in which a part of the sheet protrudes and deliver the sheet from the position toward a circulation path while reversing the conveying direction of the sheet; a circulating unit configured to convey the sheet delivered toward the circulation path along the circulation path and return the sheet to the conveying path while the sheet is reversed; and a control unit configured to control the reversing unit when a jammed sheet is detected in the device at the sheet conveying destination.

A sheet conveying apparatus capable of conveying a sheet as a conveyance target in a conveyance path includes a detector that detects capacitance in a predetermined detection region in the conveyance path; and a basis weight identifier that identifies a basis weight of the sheet as the conveyance target on the basis of first capacitance detected by the detector while the sheet as the conveyance target does not pass through the detection region and second capacitance detected by the detector while the sheet as the conveyance target passes through the detection region.

摘要:
An image forming apparatus performs a continuous printing job in a normal sheet interval mode as an initially setting mode when an arrival waiting control such as a feed retry control is not performed. In the normal sheet interval mode, a feeding action is performed such that a sheet interval between successive two sheets is set at a predetermined normal sheet interval during the continuous printing. When the initially setting mode is not maintained, the continuous printing is performed with switching the sheet interval mode to an extended sheet interval mode for performing the feeding action with an extended sheet interval which is longer than the normal sheet interval.
