A sheet processing apparatus which is capable of improving operability while suppressing an increase in apparatus size. In a front cover insertion mode, an insertion sheet for a front cover is inserted into a bundle of sheets on which images have been formed, and in a rear cover insertion mode, an insertion sheet for a rear cover is inserted into the bundle of sheets. Insertion sheets for the front cover and insertion sheets for the rear cover are set with the same orientation in a manual feed tray. An insertion sheet for the front cover stored in the manual feed trayis conveyed to a finisherin one of a face-down state and a face-up state. An insertion sheet for the rear cover stored in the manual feed trayis conveyed to the finisherin the other of the face-down state and the face-up state. The insertion sheets for the front cover and for the rear cover conveyed from the manual feed trayand the sheets on which images have been formed are stacked on the finisher

Sheet processing apparatus having a sheet insertion function, control method therefor, image forming apparatus, and program for implementing the control method

There is provided an image forming system that are capable of preventing a user or operator from forgetting to carry out a maintenance operation based on required sub-maintenance items after execution of a maintenance operation based on an associated maintenance item, such as component replacement, cleaning, or adjustment. A table of maintenance items and sub-maintenance items associated with respective ones of the maintenance items is stored in a ROM. When a CPU determines that a maintenance operation based on a selected one of the maintenance items has been completed, the CPU determines whether or not there is any sub-maintenance item associated with the selected maintenance item, by referring to the table. When it is determined that there is one or more sub-maintenance items associated with the selected maintenance item, a CPU provides control to display the sub-maintenance item or items in an operating/display unit.

Image forming system and maintenance execution program

An image forming system that makes it possible to open or remove an external cover of an apparatus to perform maintenance on the apparatus even while the system is operating. Out of a plurality of conveying paths, at least one conveying path for which at least one part related to the conveying path can be subjected to maintenance is determined, in accordance with a type of the image forming process being executed. The conveying path for which it has been determined that the part related to the conveying path can be subjected to maintenance is displayed on a display device.

Image forming system, maintenance method applied thereto, and program for causing a computer to implement the maintenance method

A sheet processing apparatus which is capable of accurately superimposing or aligning sheets discharged from an image forming apparatus during buffering even when the space intervals between the sheets are reduced. A sheet processing apparatus sequentially receives sheets discharged from an image forming apparatus and carries out post-processing on the sheets. During execution of the post-processing on the sheets, a plurality of sheets are discharged successively from the image forming apparatus and superimposed one upon another around a buffer roller. The conveying speed of the sheets is controlled such that a conveying time period over which a sheet preceding a final one of the sheets to be superimposed one upon another around the buffer roller is conveyed over a predetermined path section is shorter than a conveying time period over which the final one is conveyed over the predetermined path section.

Sheet processing apparatus and control method therefor

There is provided an image forming apparatus that is capable of preventing input errors and eliminating the necessity of complicated input operations in making settings for a sheet mixing operation in which color image output sheets and black-and-white image output sheets are mixed into one group. A stacker tray stores sheets with color images formed thereon by a color MFP and is equipped with a storage device, into and from which information relating to the sheets can be written and read. A black-and-white MFP operates in response to attachment of the stacker tray to an inserter attached to the black-and-white MFP, to execute an image formation job by providing control such that the sheets with color images formed thereon stored in the stacker tray and sheets with black-and-white images formed thereon by the black-and-white MFP are mixed according to the information stored in the storage device of the stacker tray.

Image forming apparatus, sheet containing device, sheet inserting device, book-binding system, and sheet processing apparatus

Sheet thickness data obtained from the output of a sheet thickness detecting sensor are calculated to thereby calculate a sheet bundle thickness. When the sheet bundle thickness reaches a predetermined value, other aftertreatment differing from a set aftertreatment is executed.

Aftertreatment apparatus, and controlling method, program and storage medium therefor

There are provided an image forming apparatus and a method of controlling the same are provided, which are capable of conveying an insert sheet of a proper page in carrying out a recovery process and simplifying the recovery process, and a storage medium storing a program for executing the method. When a printing start instruction is input and an insert mode has been set, an insert sheet is fed. It is determined whether the insert sheet is for a top page of a copy (bundle) or not. When the insert sheet for the top page is detected, a proper printing operation in the insert mode is started. If the insert sheet is not determined to be for the top page, it is judged that the insert sheet has not been correctly set on the inserter tray, and then the insert sheet is discharged to a non-sort tray. Then, insert sheets are discharged to the non-sort tray until the insert sheet for the top page is detected.

Image forming apparatus that provides insert sheet in proper order, method of controlling the same, and storage medium therefor

A sheet handling apparatus is provided, which is comprised of a plurality of inserter trays for stacking thereon insert sheets to be inserted between recording sheets having images formed thereon. Sheet feeding modes for feeding insert sheets include two kinds, i.e. S-stacking mode and F-stacking mode, that can be set by a mode key displayed on a sheet feeding mode setting screen view. In the S-stacking mode, only first-page insert sheets are stacked on a first inserter tray, and only second-page insert sheets and third-page insert sheets are stacked on second and third inserter trays, respectively. In the F-stacking mode, insert sheets are stacked in order of page on an inserter tray. Sheet feeding is suitably controlled by stacking insert sheets on inserter trays in manners corresponding to respective selected stacking modes.

Sheet handling apparatus which inserts insert sheets between recording sheets having image formed thereon, method of controlling same, image forming apparatus and storage medium therefor

To maintain high productivity and performing high-grade processes while minimizing deviation of a sheet process position in a direction at a right angle to a sheet conveying direction whatever types of sheets are to be processed, timing for starting detection of an end position of each of the sheets is controlled so as to execute the detection of the end position of each of the sheets at a vicinity of a sheet processing position on the sheet at which a sheet process is executed.

Sheet processing apparatus, control method therefor, sheet processing method, and storage media

The present invention provides a sheet process device capable of performing a sheaf discharge operation to discharge sheaves of sheets stacked on a process tray to a stack tray, without discharging a next sheet to the process tray during the sheaf discharge operation and stopping an operation on a body side of an image formation apparatus. In the sheet process device, for example, in a case where an original consisting of six sheets of paper is carried, the first to third sheets are stacked on the process tray as they are without any designation, and the following fourth sheet is designated as a sheaf discharge sheet since it is the sheet two before the final sheet of the sheaf, whereby the sheaf discharge of the first to fourth sheets is performed. The fifth sheet after the sheaf discharge is designated as a wind sheet since a value of a wind counter has been set to be '2'. Then, when the fifth sheet is stacked on the process tray together with the sixth sheet designated as the final sheet of the sheaf, the sheaf discharge is performed.

Sheet process device once stacking received sheets on first stack means and then transferring them to second stack means

An image-forming system is composed of an image-forming apparatus body, a folding device, a bookbinding device, and a finisher, which are connected to the image-forming apparatus body. In the image-forming system, in order to support maintenance, an available period of time for maintenance for each processing module (a unit or a device sectionalized in a processing functional unit) is calculated based on contents of a job presently in execution and contents of registered jobs so as to display the available period of time for maintenance of the calculated processing module on an operation display.
