Provided is an image forming system that can prevent unnecessary down time and spoiled paper from being caused, thereby improving productivity. The image forming system includes an image forming portion, a detecting portion, and a controlling portion. When an abnormality has been detected by the detecting portion, when a reading portion for reading an image formed on a recording medium by the printing operation of the image forming portion is provided, the controlling portion causes the reading portion to function to continue the printing operation, and at the detection of the abnormality on the basis of the read image, stops the printing operation to cause a notifying portion to perform notification related to the abnormality, and when the reading portion is not provided, the controlling portion stops the printing operation to cause the notifying portion to perform the notification related to the detected abnormality.

Image forming system, control method of image forming system, and control program of image forming system

An image forming apparatus including: plural sheet supplying sections which accommodate a recording sheet and feed out the recording sheet; an image forming section which forms an image on the recording sheet, fed out from the sheet supplying section, based on a printing job; a memory section which stores information of the printing job, including information of the recording sheet; and a control section which determines a sheet supplying section, based on the information of the recording sheet, included in the printing job stored in the memory section, and displays an event using a time axis provided on a vertical axis or a horizontal axis on a display section, the event is generated by a schedule for using the sheet supplying section determined above, and is generated when the sheet supplying section is switched to another sheet-supplying section, or the event is generated at a predetermined time cycle.

Image forming apparatus with plural sheet supplying sections

There is described an image forming system, which comprises an image forming apparatus to produce a printing material as one group of recording mediums or plural printing materials as plural groups of recording mediums from a single document set, and a finisher to apply a finish processing to said recording mediums, wherein the image forming system includes a controlling section to control so that, if a mixture mode is set, a non-finished recording medium and a finished recording medium within the single group are stacked at a same recording-medium stacking position on a stacking tray.

Image forming system, image forming apparatus and program

A feeding apparatus including a feeding roller for conveying a sheet, a separation roller for conveying the sheet in a reverse direction, a transmission mechanism for transmitting the rotational force to the feeding roller, a limited force reverse transmission mechanism for transmitting the rotational force to the separation roller through a torque limiter, a forced reverse transmission mechanism for directly transmitting the rotational force to the separation roller, a temperature detector and a controller, wherein the controller controls the separation roller to receive rotational force through the forced reverse transmission mechanism after the limited force reverse transmission mechanism transmits the rotational force to the separation roller, then allows the limited force reverse transmission mechanism to transmit the rotational force to the separation roller, or to rotate the feeding via the transmission mechanism and the limited force transmission mechanism to transmit the rotational force to the separation roller.

Feeding apparatus, and image forming apparatus incorporating feeding apparatus

Disclosed is an image forming apparatus including: a plurality of paper feed trays in which paper sheets are to be stacked; paper feed units each provided to each of the plurality of paper feed trays, the paper feed units sucking or discharging air in accordance with setting values corresponding to types of paper sheet to carry the paper sheets stacked in the respective paper feed trays toward a paper path; a storage unit to store the setting values for the paper feed units according to the types of paper sheet; an input unit to input a change instruction value for changing at least one of the setting values; and a control unit to change the at least one of the setting values stored in the storage unit into the change instruction value and to store the changed at least one of the setting values into the storage unit.

Image forming apparatus

A sheet finisher includes: a sheet stacker for stacking sheets outputted from an image forming apparatus to form a sheet bundle; a binder for binding the sheet bundle stacked on the sheet stacker; an ejection device for ejecting out of the sheet finisher at least one of the sheet bundle stacked on the sheet stacker and the sheet bundle which has been bound; an ejection tray for stacking the ejected sheet bundle or the bound sheet bundle sequentially; and a controller for controlling the ejection device to make the bound sheet bundle to wait on the sheet stacker, to make a sheet outputted from the apparatus which have not been bound to stack sequentially on the bound sheet bundle, and to make the bound sheet bundle and the sheet stacked on the bound sheet bundle as a unit to eject to the ejection tray.

Sheet finisher and control method thereof

A control method is provided for sheet-feeding in an image forming apparatus in which a sheet is fed to an image forming section of the image forming apparatus having a finisher which receives the sheet on which the image is formed and finishes the sheet. The control method includes the steps of: conducting a continuous image forming process that makes plural sets of sheets each on which the image has been formed; and controlling a starting of a sheet-feeder which feeds a first sheet of a set of sheets to the image forming section, according to a logical product of a condition on the continuous image forming process in the image forming apparatus and a condition of an operating process in the finisher.

Image forming apparatus and control method of sheet feeding therein

An image recording apparatus includes a memory for storing an image information of each page; an image forming device for recording an image onto a recording sheet for each page on the basis of the image information in the memory; a recording sheet conveyor for conveying a recording sheet to the image forming device to record an image on one side thereof, and after that, conveying again the recording sheet to the image forming device to record an image on another side thereof, with no recording sheet being stacked during conveyance, and the recording sheet being conveyed along a specified conveyance path, and a predetermined maximum number of recording sheets can exist within the specified conveyance path. The apparatus further includes a controller for controlling the image forming device and the recording sheet conveyor so that a cycle of an image forming operation corresponding to the maximum number of recording sheets is repeated until a remaining number of pages in the memory to be recorded is less than the maximum number of recording sheets.
