Image forming system and program thereof

A book-binding apparatus having: a reception vessel to receive glue in liquid form; application section to apply the glue in the reception vessel to a sheet; a hopper to receive a raw material of the glue for refill; a refilling section to refill the raw material of the glue from the hopper to the reception vessel; and a control section to control the refilling section, wherein the raw material of the glue is refilled into the reception vessel in a period where application of the glue is not carried out after application of the glue is completed.

Book-binding apparatus and image forming system

A sheet conveying apparatus is connected between an image forming apparatus and a post-processing apparatus to receive the sheet ejected from the image forming apparatus, and to eject the sheet to the post-processing apparatus. The sheet conveying apparatus receives, from the post-processing apparatus, a sheet reception line speed information showing a line speed for the post-processing apparatus to receive the sheet, and receives, from the image forming apparatus, a sheet ejection line speed information showing a line speed for the image forming apparatus to eject the sheet. A conveyance line speed control section controls the conveyance line speed at the time of receiving the sheet from the image forming apparatus based on a sheet ejection line speed information, and controls the conveyance line speed at the time of ejecting the sheet to the post-processing apparatus based on a sheet reception line speed information.

Sheet conveying apparatus and image forming system

In a sheet post processing apparatus having a folding device that carries out the process of book folding by folding either one sheet or a plurality of sheets at a time on the sheets discharge from the image forming apparatus, a sheet stacking section that successively stacks the booklet-folded sheets, and a control unit that controls the sheet post processing apparatus, said control unit controls said folding device so that said booklet folding process of said sheets is carried out at the portions of two folding lines which are almost parallel thereby obtaining a square-shaped back of booklet.

Sheet post processing apparatus and image forming system

An image forming system having an image forming apparatus for forming an image onto a recording medium, and a plurality of finishing apparatus for processing the recoding medium ejected from the image forming apparatus, each finishing apparatus of the plurality of finishing apparatuses includes, a communication device for controlling communication between the image forming apparatus and the finishing apparatus itself, a first communication line for sending and receiving data between the finishing apparatus and the image forming apparatus through the communication device for controlling the finishing apparatus, and a second communication line adapted for bypassing the communication device arranged in the finishing apparatus.

Image forming system and finishing apparatus

An image forming system including: an image forming apparatus which executes a print job to form an image on a recording medium; and a post processing apparatus which carries out a post processing to the medium on which the image has been formed; wherein, the image forming apparatus includes a control section to control the image forming apparatus such that, if there is a waiting period in a preceding print job being under execution, a succeeding print job is executed during the waiting period.

Image forming system and image forming apparatus

When a job cancellation instruction has been specified, if the number of the recording sheets loaded on the stacker device of a post-processing apparatus is not greater than the predetermined number of sheets, the aforementioned recording sheets are ejected without being subjected to the process of stapling and if it is greater than the predetermined number of sheets, the recording sheets having been stapled are ejected.

Image forming apparatus

A sheet finisher includes a sheet stacker for stacking sheets conveyed from an image forming apparatus to form a sheet bundle and a binding device for binding the sheet bundle with a staple, further includes a center folding device for center folding sheets conveyed from the image forming apparatus, a first conveying device for conveying sheets conveyed from the image forming apparatus to the sheet stacker without passing through the center folding device, and a second conveying device for conveying the sheets to the sheet stacker via the center folding device.

Sheet finisher

An image forming apparatus includes an image forming member to form an image to an recording material, a plurality of sheet finisher units, each of which performs different sheet finishing to the recording material on which the image has formed, a plurality of indicating member provided respectively at least one to the each sheet finisher unit, an input member to accept an input of a sheet finishing mode corresponding to the sheet finishing performed by the sheet finisher unit, a sheet finishing judging member to judge the sheet finisher unit performing the sheet finishing corresponding to the input sheet finishing mode, and an indicating control member to light the indicating member provided to the judged sheet finisher unit in a first display mode.

An image forming system includes: an image forming apparatus capable of conveying a recording sheet at a predetermined speed; at least one finisher capable of conveying the sheet eject from the image forming apparatus at a prescribed speed to process the sheet; and a controller for changing a conveyance speed of the recording sheet in the finisher to be higher than that of the sheet in the image forming apparatus.

Finisher with increased conveyance speed

The present invention concerns a paper sheet cutting apparatus which cuts the front end portion opposite to the fold, where both the leading edge and trailing edge get together by center folding, and an image forming apparatus equipped with the paper sheet cutting apparatus. The sheet cutting apparatus includes a conveying device for conveying a booklet; a stopping device for stopping the booklet at a predetermined position; a cutting device for cutting the front end portion of the booklet; and a controlling section to control each of the conveying device, the stopping device and the cutting device. The controlling section controls the stopping device so as to variably determine a stopping position of the booklet stopped by the stopping device, based on a number of sheets included in the booklet conveyed to the cutting device by the conveying device.
