To enable highly accurate density unevenness correction while suppressing a reduction in productivity in printing accompanying correction value calculation for density unevenness correction. Based on an image obtained by scanning a chart including patches having uniform density for each tone value, a density characteristic of each nozzle is acquired. A non-ejectable nozzle that cannot eject ink normally is detected by analyzing a pattern for detecting the non-ejectable nozzle in the image obtained by scanning the chart. At the time of acquiring the density characteristic, the density characteristic is acquired based on a density measured value of an area of the image, which corresponds to a nozzle that is not detected as the non-ejectable nozzle.

An object is to match the texture of a printed material, in addition to the tint, between different printing devices. In order to implement this object, a printed material output by a destination device is scanned and whether a certain area in image data obtained by the scan is an area printed in K color on the printed material or an area printed in CMY color mixture is determined. Then, based on the determination results, a printing parameter is determined.

An information processing apparatus and a method of controlling the information processing apparatus are provided. The information processing apparatus stores a plurality of learned models, determines whether the stored plurality of learned models include confidential information, and presents, to a user, learned models of the plurality of learned models determined to include the confidential information.

An image forming apparatus includes: an operation unit that is decentered from a center line between a right part and a left part of the image forming apparatus rightwards or leftwards and that is disposed closer to a rear face or a front face of the image forming apparatus; a human sensor that detects a user intending to use the image forming apparatus; and a controller that performs control of operation of the image forming apparatus by using a detection result of the human sensor, the human sensor having a detection range set to detect the user, the user being detectable even when the user is present at least partially outside a width range of the image forming apparatus.

A tone reproduction curve for a printing apparatus is periodically generated based on printed items produced by the printing apparatus. The tone reproduction curve is adjusted between periodic print-based generations of the tone reproduction curve by: determining the amount of area coverage of marking material applied by the printing apparatus during printing (in subsequent periods following an initial period in which the tone reproduction curve was generated); weighting the amount of area coverage in each of the subsequent periods differently based on how distant each of the subsequent periods is from the initial period to produce a weighted moving average of the area coverages of the marking material; and adjusting the tone reproduction curve based on the weighted moving average of the area coverages of the marking material.

Systems and methods which provide postage indicia using mobile communication handsets are shown. According to embodiments, users are enabled to introduce mail pieces into a mail delivery stream which are accepted as having acceptable postage indicia having value associated therewith without the use of traditional metering systems or processor-based postage generation and printing systems. Instead, a mobile communication handset is used to obtain tokens to be used as postage indicia. The tokens may be transmitted to or otherwise printed by appropriate, available printing equipment, such as facsimile machines, network printers, network photo copiers, etc., in response to a request by a mobile communication handset for postage indicia. The foregoing tokens may be printed upon various stock for inclusion with or as a mail piece. The mail piece bearing the token may be placed into the mail stream for processing and delivery using the token as activated as postage indicia.

A printing apparatus includes an image forming portion which forms a chart image on a sheet conveyed from a sheet feeding deck, a color measure portion which performs color measurement by reading the chart image formed by the image forming portion, and one or more controllers including one or more processors and one or more memories. The one or more controllers are configured to generate correction data based on color measurement results by the color measurer portion and a reference value, and perform correction for target image data by using the generated correction data. The reference value is obtained by performing color measurement by the color measure portion and is registered in association with a type of sheet on which the chart image is formed, and in a case where the type of sheet on which the chart image is formed is changed, the reference value is updated.

A device includes an operating portion, a switch and a controller. The device is operable in a first mode in which a predetermined operation is executed and in a second mode of which power consumption is reduced rather than in the first mode, and operates in a state connected to an image forming apparatus. The operating portion operates by an AC voltage supplied from an external power source. The switch supplies the AC voltage to the operating portion in a conductive state and cuts off supply of the AC voltage to the operating portion in a non-conductive state. The controller operates by a DC voltage generated from the AC voltage by a power source provided in the image forming apparatus. The controller controls to cause the switch to be in the non-conductive state so as to stop operation of the operating portion when the device shifts from the first mode to the second mode.

An image forming apparatus configured to perform image formation using a component unit configured to be attachable to and detachable from a main body of the image forming apparatus is provided. The image forming apparatus includes: an access unit configured to access a storage device included in the component unit attached to the main body; and a control unit configured to control the access unit to read and update information stored in the storage device. The storage device includes a first area and a second area configured to store use information indicating a use state of the component unit, and updating of the use information stored in the first area by the control unit is configured such that updating only within a predetermined limit is permitted, and no limit is provided on updating of the use information stored in the second area.

An information product or item, such as a for sale sign, can be configured with contact information and/or elements that link the information product to a networked system and related services (with the product being called a for information product or FIP in the description). These services can make available applications such as phone and web application that can be helpful in providing an additional mechanism/electronic media as it relates to the FIP and/or any FIP related product/object/item. These services may aid someone to whom the FIP belongs in fielding, FIP related, viewer inquires while providing the FIP viewer with more options, upon making requests to said system services. The FIP may make available linked application system services to viewers of the FIP, which may belong to someone who does not know how to link such services in other ways.
