A conveyance control apparatus includes a stacking base that stacks ejected paper sheets, a sensor that detects a paper sheet after the paper sheet is ejected according to job data before the paper sheet is stacked on the stacking base, a detection time measuring unit that measures sensor-on time during which the sensor detects the paper sheet, a storage unit that stores near-full-stack time for judging whether stacked volume on the stacking base enters into a near-full-stack state, a judging unit that judges stack state on the stacking base based on paper sheet information of the job data and a measured result by the detection time measuring unit, and a conveyance control unit that performs control to temporarily stop paper sheet feeding and then to feed predetermined number of paper sheets, when the judging unit judges that the sensor-on time is equal to or greater than the near-full-stack time.

Conveyance control apparatus

A printer which is connected to a post-processing apparatus, the post-processing apparatus performing a wrapped binding in which a paper sheet bundle including a plurality of inner paper sheets is wrapped by outer paper sheets, and which prints the outer paper sheets and inner paper sheets to be sent out to the post-processing apparatus, wherein the printer includes a control unit configured to control printing of the inner paper sheets and the outer paper sheets in cooperation with the post-processing apparatus, and the control unit is configured to set printing restart information of inner paper sheets and printing restart information of outer paper sheets, and controls a restarting of printing in accordance with the setting, when printing is restarted after an abnormal conveyance that occurred inside of the post-processing apparatus has been resolved.

Printer and storage medium

An image forming apparatus having a plurality of paper ejection devices includes a control unit which performs control to allow before a paper ejection device, which is continuously ejecting paper in the plurality of paper ejection devices, ejects paper over the maximum loading a paper ejection device which is not ejecting paper to prepare for starting an operation based on the time taken for the paper ejection device which is not ejecting paper to become operable and the number of ejectable sheets before a loading of the paper ejection device which is continuously ejecting paper reaches the maximum loading.
