An image forming system includes a first feeding portion configured to feed a recording sheet, an image forming portion, a sheet conveyance path, a second feeding portion configured to feed an inserting sheet from any of a plurality of supporting portions including a first supporting portion and a second supporting portion, a detection portion, and a controller. The controller is configured to execute, during execution of a process of feeding a first inserting sheet from the first supporting portion to the sheet conveyance path, a movement processing of moving a second inserting sheet supported on the second supporting portion to a position where a trailing edge of the second inserting sheet is placed downstream in a sheet conveyance direction of a detection position of the detection portion and thereafter stopping the second inserting sheet.

A feeding device includes a feeding device body of which a downstream end portion in a feeding direction, in which a material to be fed is fed, is mounted on a mounting portion, and that is openable and closable between a closed position where an upstream end portion is positioned above the downstream end portion and an open position where the upstream end portion is positioned on a side of the downstream end portion, a stacked portion that is provided on the feeding device body and on which the material to be fed is stacked in the open position, a detection unit that has a detection member hanging down to a downstream end portion of the stacked portion in the open position, moves to a downstream side in the feeding direction as the detection member is pressed by a downstream end portion of the material to be fed stacked on the stacked portion, and detects a stack of the materials to be fed on the stacked portion, and a restriction unit that restricts movement of the detection member to the downstream side in the feeding direction in the closed position.

The present invention provides an image forming apparatus comprising: at least one first module and at least one second module configured to execute functions corresponding respectively to the at least one first module; a first control unit configured to notify, to a corresponding second module, a request accepted by the at least one first module; and a second control unit configured to control in accordance with the notification from the first control unit, the corresponding second module, wherein the at least one first module is activated at all times from when the image forming apparatus is activated, and the at least one second module is generated as a container of an execution environment that is independent of an operating system and whose activation state is controlled by an instruction from the second control unit.

A feeding device includes a loading portion, a lifting mechanism, a conveying unit, a sheet detector, a near-end detector, and process circuitry. The loading portion stacks a plurality of sheets. The lifting mechanism lifts the loading portion. The conveying unit conveys the sheets on the loading portion. The sheet detector detects presence or absence of the sheets on the loading portion at a specified height position. The sheet count detector detects a number of sheets conveyed by the conveying unit. The near-end detector detects a near-end state in which a stack height of the sheets on the loading portion is a specified value or less. The process circuitry controls the lifting mechanism based on a detection result of the sheet detector before the near-end state is detected, and controls the lifting mechanism based on a detection result of the sheet count detector after the near-end state is detected.

An image forming device includes a casing and a medium detecting mechanism. A medium entrance is formed on the casing. The medium detecting mechanism includes a detector, a first pivoting component, a second pivoting component and a resilient component. When at least one medium enters into the medium entrance and abuts against the first pivoting component, the at least one medium drives the first pivoting component to pivot in a first pivoting direction, so that the second pivoting component is driven by the resilient component to pivot in the first pivoting direction to actuate the detector for generating a signal. When the second pivoting component is stopped from pivoting in the first pivoting direction, deformation of the resilient component allows the first pivoting component to be driven by the at least one medium to pivot relative to the second pivoting component in the first pivoting direction continuously.

A sheet feeding device includes a sheet loading table on which a bundle of sheets is stacked, an identification mark on an end face of the sheet loading table, and an imaging unit to identify the identification mark.

An image forming apparatus includes a load detection sensor located on a feeder to detect whether a print medium is loaded on the feeder, an overload detection sensor to detect an overload state of a discharger, and a controller to detect a width of the print medium according to a combination of a feeder load state of a feeder load detection signal of the load detection sensor and an overload state of a discharger overload detection signal of the overload detection sensor and control an image former to perform printing by applying different print modes according to the detected width of the print medium.

When it is judged that a predetermined operation for eliminating a cause for stopping a job is being executed, a following job is restricted from being executed prior to a stopped job. A control method for controlling a job processing apparatus for storing received jobs in a storage unit and sequentially executing the stored jobs includes determining, when a cause for stopping the job to be executed is generated, whether a state in which the cause for stopping the job is not eliminated has continued for a predetermined time, executing, when it is determined that the state in which the cause for stopping the job is not eliminated has continued for the predetermined time, a following job that follows the job is executed prior to the job, judging whether a predetermined operation for eliminating the cause for stopping the job is being executed, and restricting, when it is judged that a predetermined operation for eliminating the cause for stopping the job is being executed, the following job is restricted from being executed prior to the job.

An image forming apparatus includes a storage unit to store recording sheets, an image forming unit, an insertion unit, including an interleaving sheet tray on which an interleaving sheet is to be stacked, and to insert the interleaving sheet fed from the interleaving sheet tray between recording sheets conveyed from the image forming unit. The control unit selects between a first mode and a second mode to execute based on a detected remaining amount of recording sheets in the storage unit. The first mode is a mode for feeding the interleaving sheet, which is to be inserted, from the interleaving sheet tray regardless of whether a presence of the recording sheet in the storage unit is detected. The second mode is a mode for feeding the interleaving sheet from the interleaving sheet tray based on that presence of the recording sheet in the storage unit is detected.

An image forming system includes a first feeding portion configured to feed a recording sheet, an image forming portion, a sheet conveyance path, a second feeding portion configured to feed an inserting sheet from any of a plurality of supporting portions including a first supporting portion and a second supporting portion, a detection portion, and a controller. The controller is configured to execute, during execution of a process of feeding a first inserting sheet from the first supporting portion to the sheet conveyance path, a movement processing of moving a second inserting sheet supported on the second supporting portion to a position where a trailing edge of the second inserting sheet is placed downstream in a sheet conveyance direction of a detection position of the detection portion and thereafter stopping the second inserting sheet.
