Disclosed is an image forming apparatus, including: a job receiver that receives a print job; a printer that executes an image forming in accordance with the print job received by the job receiver; and a hardware processor that: receives an adjustment content and a setting of an execution starting condition of an adjustment for an adjustment item relating to the image forming, and registers the adjustment content and the execution starting condition as a profile; and executes the adjustment in accordance with the adjustment content set in the registered profile when the execution starting condition set in the profile is satisfied.

Embodiment of systems and methods for the sending, delivery or receiving of faxes are disclosed herein. In particular, certain embodiments include a fax connector that may be deployed at users' sites, and a fax registration system that may be deployed remotely from these users' site. The fax connector can be accessed at a user's site over a computer based network in order to perform functions associated with faxing, including sending, receiving and obtaining status on faxes. The fax connector deployed at a sending user's site communicates with the fax registration system to obtain destination data associated with a recipient user's fax connector and transmits the fax to the destination fax connector over the computer based network based on the destination data obtained from the registration system. The fax can then be presented to the recipient at the recipient user's site.

An image forming apparatus that facilitates user's determination of necessity of setting an inspection resuming page and is improved in jam processing efficiency. A sheet having an image formed thereon by an image forming unit is conveyed along a sheet conveying path. A sheet inspection device inspects the image on a sheet being conveyed through sheet conveying path. When a jam occurs in the conveying path, image formation by the image forming unit is interrupted. When jammed sheets are removed, formation of images including those formed on the jammed sheets is resumed. When a leading one of the jammed sheets is on a downstream side of the sheet inspection device, the image formation is resumed from an image formed on the leading jammed sheet, based on a user instruction.

An information processing apparatus includes a reading unit, an edge extraction unit, a feature point search unit, a document area size calculation unit, a user operation unit, and a multi-feed determination unit. The reading unit optically reads a document to generate image data. The edge extraction unit extracts an edge of the document from the image data. The feature point search unit searches edge data of the edge extracted by the edge extraction unit for a feature point. The document area size calculation unit calculates a document area size from the feature point found by the feature point search unit. The user operation unit is used by a user to specify a document size. The multi-feed determination unit compares the document area size calculated by the document area size calculation unit with the user-specified document size so as to determine whether multi-feed of the document has occurred.

A maintenance system includes an image forming apparatus that performs image formation by a setting depending on the replacement part using a replaceably configured replacement part and a portable terminal that performs near field communication with the portable terminal. The portable terminal includes an image reading part that reads part information of the replacement part from a printed part affixed to the replacement part and a near filed communication part that transmits the part information read by the image reading part via the near filed communication. The image forming apparatus includes a non-contact IC tag in which the part information is written based on power generated from the near filed communication and an reflection processing part that reads the part information from the IC tag at the time of power on and reflects the part information in the setting.

An image reading device includes: contact glass, a document reading section that reads a document loaded on the contact glass while a moving mechanism moves in a document reading direction, a reading control section that causes the document reading section to read the whole contact glass at a rate of once per a predefined number of times N1, a first contamination detection section, and a report section. The first contamination detection section detects, from image data of the whole contact glass obtained through the reading by the document reading section, contamination of the contact glass present in a region other than a region loaded with the document. The report section, upon detecting by the first contamination detection section the same contamination from all the pieces of image data obtained consecutively a predefined plural number of times M1, reports a user that the contamination is present on the contact glass.

Facsimile reception is prohibited when an operation mode in which a service person performs printing for the purpose of maintenance is set.

Provided are a print control apparatus and a non-transitory computer-readable storage medium storing a color calibration control program. A print control apparatus includes an information storage processing section which stores measured color values into a database which stores history information of color measurement, where the measured color values are obtained by measuring colors in a color chart by using a printing device. The print control apparatus further includes a color defining section which defines a specific color by referring to the database, and a color calibration controlling section which, while the printing device is processing a print job, causes the printing device to measure the specific color, determines whether to calibrate the printing device on the basis of a change with time in the measured color value of the specific color, and calibrates the printing device according to the determination result.

A method of controlling an image reproduction system, wherein a process duration is estimated on the basis of a measured time (D) for the processing of a number (n) of pages that have been processed already, the method comprising storing a digital table which contains a number of pre-defined job types as well as a respective correction factor (A4) for each job type; when a job is received (S1), assigning (S2) a job type to the received job; calculating (S3) a first estimate (D1) for a time needed for processing at least a specified collection of pages from the job; calculating (S4) a second estimate (D2) by multiplying the first estimate (D1) with the correction factor (A4); when said specified collection of pages has been processed, calculating a deviation of the first estimate (D1), and updating (S9) the correction factor (A4); and storing the updated correction factor.

An inspection apparatus includes a controller having one or more processors which executes instructions stored in one or more memories, the controller being configured to receive an inspection level that is used in an inspection process of images that have been read by a reading apparatus from images formed on sheets conveyed consecutively from an image formation apparatus by execution of a job; and execute the inspection process, wherein the controller is capable of receiving a change in the inspection level during execution of the job, and in a case where the change in the inspection level is received, the controller performs the inspection process of images formed by the job at the inspection level changed after receipt of the change.
