A printing system includes processing circuitry. The processing circuitry acquires print data of a plurality of pages and extracts comparison data from the print data for each page. The processing circuitry, from first image data read from a printed material on which the print data is printed, acquires second image data at a position corresponding to the comparison data, for each page of the printed material. The processing circuitry outputs a comparison result of the comparison data and the read image data for each page.

The recording device includes an upstream transport roller pair capable of transporting a medium, a recording head configured to record an image by discharging ink at a predetermined timing on the medium transported downstream in a Dl direction by a predetermined transport amount by the upstream transport roller pair while moving in a Y-axis direction intersecting the D1 direction, an image capturing unit configured to read the image recorded on the medium by the recording head, and a control unit, wherein the control unit has a function of performing maintenance for a discharge failure of the ink, a correction of the transport amount, and a correction of the discharge timing of the ink based on the reading result of the image read by the image capturing unit.

A printer, capable of appropriately extending an existing replacement recommendation time of a component determined based on a life prescribed for the component, includes: a time determination unit (timer), a comparison examination unit (comparator), and a notification unit (notifier). The timer determines a time at which replacement of a component is recommended based on tendency information indicating a deterioration tendency of the component with respect to an operation status. The tendency information is generated from collection and storage of information on the operation status collected from a plurality of printers and information on a degree of deterioration at a disposal time of the component. The comparator compares a time output by the time determination unit with a predetermined life of the component, and examines whether to perform recommendation for component replacement. The notifier notifies of information on recommendation for component replacement based on an examination result of the comparator.

A reading device and an image forming apparatus are provided. The reading device includes an image reading device configured to read an image on a recording medium being conveyed, a background device serving as a background image when the image is read by the image reading device, and a foreign-object detector configured to compare a first read image obtained as the background device is read by the image reading device with a second read image obtained as the background device and the recording medium are read by the image reading device to detect an attached foreign object. The image forming apparatus includes the reading device and an image forming device.

An image forming apparatus comprises a reading unit that reads a document sheet, specifies image data of a comparison source document sheet, among image data of document sheets read by the reading unit; extracts a difference by comparing the image data of the specified comparison source document sheet, and image data of each of other document sheets included in the read document sheets; and creates a composite image by composing the extracted difference and the image data of the comparison source document sheet.

An image reading apparatus includes a light source to emit at least light in a first wavelength range and light in a second wavelength range, a background member having different light reflectances in the first and second wavelength ranges, an imaging device, and circuitry. The imaging device receives reflected light from the background member irradiated with the light in the first wavelength range, and generates first read information. The imaging device further receives reflected light from the background member irradiated with the light in the second wavelength range, and generates second read information. The circuitry detects presence or absence of a first foreign substance based on a difference in reading level of the first read information generated by the imaging device; and detect presence or absence of a second foreign substance based on a difference in reading level of the second read information generated by the imaging device.

An image processing apparatus includes an acquisition unit configured to acquire a plurality of image data read from a plurality of areas of a print product, and an evaluation unit configured to obtain degrees of streaks in the plurality of areas and tilts in the plurality of areas using the plurality of image data and evaluate image quality of the print product based on the degrees and the tilts.

Provided is a method of operating an image forming apparatus. The method includes: calculating a remaining lifespan of at least one component consumed through an image forming job in the image forming apparatus; determining whether to proceed with a refill operation to refill a toner in a cartridge of the image forming apparatus, based on the remaining lifespan of the at least one component; and displaying guide information to guide the refill operation based on a result of the determining.

An information processing apparatus includes a processor configured to: obtain plural images each including any of plural objects; and output report information that is information generated based on an analysis result regarding the plural objects in the plural images, and that is information for reporting according to which of two or more objects, among the plural objects, included in an image the image is to be corrected.

An image processing apparatus for inspection of a sheet on which a code image obtained by encoding predetermined information is printed includes: a first acquisition unit which acquires positional information indicating a position and a size of the code image in the sheet; a second acquisition unit which acquires a plurality of read images obtained by a plurality of reading units reading different portions of the sheet, respectively, wherein the read images become an image indicating the entire sheet by being combined; a determination unit which determines whether any one of the read images includes the entire code image based on the positional information; and an extraction unit which extracts the predetermined information by, in a case where there is a read image including the entire code image, reading the code image in that read image.
