An image forming apparatus to form images on a series of sheets includes: an image forming processor to form an image on each sheet; a reader to read each sheet and to output read data; an inspector to determine a quality of each sheet using the read data; and a controller to discharge each sheet determined as not satisfying a predetermined quality criteria into a second tray other than a first tray specified in a print job. When copies specified in the print job are each constituted by one of the series of sheets and at least one sheet of the series of sheets is on a transport path as at least one remaining sheet, the controller processes each of the at least one remaining sheet in such a way that if the remaining sheet satisfies the predetermined quality criteria, the controller discharges the remaining sheet into the first tray.

An image forming apparatus includes: a transport device that transports a sheet placed on a sheet holding member; a detector that detects one type from among a first number of types as a type of the sheet transported by the transport device; a display that displays the type of the sheet placed on the sheet holding member; and an input device that accepts an instruction related to a display pattern of the type of the sheet, wherein the input device accepts an instruction to select the display pattern from a first display pattern in which the type of the sheet is selected from among the first number of types, and a second display pattern in which the type of the sheet is selected from a second number of types, and the display displays the type that is a result of the detection by the detector.

A medium conveying apparatus includes a conveying roller to convey a medium, an imaging device to generate an input image acquired by imaging the conveyed medium, and a processor to extract edge pixels from the input image, detect a degree of roundness at a corner of the medium in the input image based on the edge pixels, determine whether the conveyed medium is an ID card based on the degree of roundness, and control the conveying roller based on a result of the determination or outputs the result of the determination.

An image forming apparatus includes: a reception part that receives specification of a print mode and specification of a sheet type to be used for printing; a sheet supply part that sends a sheet to a sheet conveyance path; a detection part that detects a type of a sheet sent to the sheet conveyance path; and a hardware processor that controls a printing operation, wherein when a sheet type received by the reception part is a type for which printing in the print mode received by the reception part is allowed, the sheet supply part sends a sheet to the sheet conveyance path, the hardware processor determines whether or not the print mode received by the reception part is a prohibition mode, when it is determined that the print mode is the prohibition mode, the detection part detects a type of a sheet sent to the sheet conveyance path.

A number-of-documents calculator calculates a number of original documents on a document placement tray from their weight detected by a weight sensor. A controller sets a resolution to a predetermined first resolution when the number of original documents is less than a predetermined number or sets the resolution to a predetermined second resolution lower than the first resolution when the number of original documents is not less than the predetermined number, and allows a document reader to read images of the original documents at the set first or second resolution. A special document detector determines, based on image data on the original document, whether the original document satisfies a predetermined condition, and detects the original document satisfying the condition as a special original document preferably to be read at a third resolution higher than the first resolution. A notifier notifies a user that the special original document has been detected.

An image forming apparatus includes an image reading part, an image forming part, and a sheet feeding cartridge. The image reading part reads a document and obtains image data of the document. The image forming part forms an image on a sheet on the basis of the image data. The sheet feeding cartridge stores several kinds of the sheets. In a case where predetermined sheet feeding information is applied on the document, the sheet feeding information is read on the basis of the image data. Conveying of the sheet is controlled so as to convey the sheet corresponding to the sheet feeding information from the sheet feeding cartridge to the image forming part and, on the other hand, to eject the sheet not corresponding to the sheet feeding information from the sheet feeding cartridge without passing through the image forming part.

An image forming apparatus, includes: a media sensor that detects a sheet type; a fixer that fixes the image on a sheet; a storage that stores a fixing temperature for each sheet type; and a hardware processor that controls power supplied to the fixer by pulse-width modulation (PWM) control and controls a temperature of the fixer to the fixing temperature corresponding to the sheet type detected by the media sensor.

A non-transitory computer readable medium storing computer readable instructions configured to, when executed by a processor of a computer, cause the processor to: receive preparation instruction information from an information processing terminal, in response to receiving the preparation instruction information, cause an operating unit to execute at least one pre-printing operation of which operation content accords with a particular execution condition indicated by particular condition information in the preparation instruction information, receive print instruction information from the information processing terminal, the print instruction information instructing execution of the printing operation according to an execution condition, in response to receiving the print instruction information, determine whether the at least one pre-printing operation has already been executed; and in response to determining that the at least one pre-printing operation has been executed, cause the operating unit to execute the printing operation indicated by the print instruction information.

A machine learning applies page parameters of a complex document file to transform the complex document file into pre-press operator action predictions for the complex document file. Prompts are generated on an operator console for a pre-press operator to confirm the pre-press operator action predictions, and to apply responses to the prompts to enhance the classification model and to control a printer.

An information processing apparatus performs processing for putting a width of a line in an output in a case where printing is performed by a first printing apparatus based on print data including a line close to a width of a line in an output in a case where printing is performed by a second printing apparatus based on the print data. A first acquisition unit is configured to acquire first information relating to an output in a case where printed matter including a plurality of line width detection images is printed by the second printing apparatus.
