An image forming system includes: an image forming apparatus; and a recording material information detecting apparatus provided outside the image forming apparatus, wherein the recording material information detecting apparatus includes a recording material information detector that detects recording material information about a recording material, and the image forming apparatus includes: an image former; an operation detector; and a hardware processor.

An image reading apparatus includes a detection unit, a display unit, a conveyance control unit, and a reading unit. The detection unit detects that a document is placed on a document tray. When the detection unit detects that the document is placed on the document tray, the display unit displays an object related to setting of a thickness of the document if a predetermined function is not being performed. The conveyance control unit conveys the document based on information indicating the document thickness set via the object. The reading unit reads an image of the conveyed document.

An image forming apparatus includes an exit tray, a printing unit, an output unit, and a control unit. A printing medium after printing is discharged to the exit tray. The printing unit performs printing of an image on the printing medium, and discharges the printing medium after printing to the exit tray. The output unit outputs information. The control unit causes the printing unit to stop the printing of the image on the printing medium, and causes the output unit to output alert information on discharge of the printing medium to the exit tray, if the number of printing media on the exit tray is equal to or greater than a predetermined first threshold value. The control unit causes the printing unit to stop the printing of the image on the printing medium, and causes the output unit to output the alert information, if the number of printing media on the exit tray is equal to or greater than a second threshold value which is smaller than the first threshold value, and if a predetermined printing stop condition is satisfied.

A reading unit is configured to capture an image of a shadow generated at a leading end of a document, and a control unit is configured to estimate a thickness of the document based on a pixel value of the shadow. A multifeeding error is displayed on a display unit when it is determined as thin paper in a thick paper determination. The control unit turns multifeeding detection to OFF and stands by until a feeding is completed, and upon completion, returns the multifeeding detection to ON.

A sheet conveying device includes a reception processing portion and a conveyance control portion. The reception processing portion receives an input operation to input conveyance route information that indicates which of a first conveyance route, leading to a first discharge portion via a first conveyance path that extends straight from a sheet placement portion, and a second conveyance route, leading to a second discharge portion, which is different from the first discharge portion, via a second conveyance path that includes a curved portion branching off from the first conveyance path, each sheet included in a sheet stack placed on the sheet placement portion is conveyed along. The conveyance control portion sequentially conveys each sheet included in the sheet stack placed on the sheet placement portion along either the first conveyance route or the second conveyance route according to the conveyance route information input through the input operation.

An image forming apparatus includes an exit tray, a printing unit, an output unit, and a control unit. A printing medium after printing is discharged to the exit tray. The printing unit performs printing of an image on the printing medium, and discharges the printing medium after printing to the exit tray. The output unit outputs information. The control unit causes the printing unit to stop the printing of the image on the printing medium, and causes the output unit to output alert information on discharge of the printing medium to the exit tray, if the number of printing media on the exit tray is equal to or greater than a predetermined first threshold value. The control unit causes the printing unit to stop the printing of the image on the printing medium, and causes the output unit to output the alert information, if the number of printing media on the exit tray is equal to or greater than a second threshold value which is smaller than the first threshold value, and if a predetermined printing stop condition is satisfied.

A print management system having a control apparatus and an image forming apparatus with sheet feeding cassettes includes a sheet data registration unit to register sheet data indicating an attribute of each print sheet, a sheet feeding cassette selection unit to select a sheet feeding cassette, and a sheet data selection unit to select sheet data about at least one type of print sheet from the registered sheet data. An adjustment value setting unit sets adjustment value information during image formation while feeding the selected print sheet and a database setting unit sets, in association with each other, the attribute of the selected sheet feeding cassette, the selected sheet data about the print sheet, and the set adjustment value information. The database setting unit allows setting to one piece of sheet data adjustment value information about each sheet feeding cassette selected by the sheet feeding cassette selection unit.

In an image processing system in which when a paper document is computerized, a file name or the like is set by using a recognized character string obtained by performing OCR processing, so that time and effort of a user when a plurality of documents is computerized en bloc is reduced. Learning data is generated by registering positional information relating to a recognized character string used for setting of a property relating to a scanned image in association with a document form of the scanned image. Then, in a case where the learning data is generated in response to setting of the property being performed for a first scanned image that is selected from a plurality of scanned images included in a list, a scanned image having a document form similar to a document form of the first scanned image is determined among other scanned images included in the list.

In a case where it is determined that a document is left behind, a display control unit is configured to control display of an icon using a result of detection by a second detection unit without using at least a result of detection by a first detection unit.

An information processing apparatus includes: a processor configured to: acquire information on a folding manner in which a folding device folds a medium; and when the folding manner does not allow reading of a folding position of the medium with the medium folded, cause a display to display information so as to prompt a user to unfold and read the medium.
