An image forming system includes: an image forming apparatus including an image forming unit for forming an image on a sheet, an image reading unit for reading a sheet surface and generating a scan image, an image inspection unit for detecting abnormalities within the scan image, and a history generating unit for generating detection information of each of the abnormalities and generating a history image by embedding the detection information in the scan image; a storage device for storing the history image; and a user terminal for displaying an abnormality detection result and inputting a user's evaluation of the abnormality detection result, wherein the image forming apparatus further includes a parameter setting unit for finally determining the abnormalities depending on the user's evaluation, and determining and setting abnormality detection parameters such that the abnormalities finally determined are detected, and the abnormalities not finally determined are not detected.

Systems, apparatuses and methods are provided to allow for detection of an impact to an output apparatus. Such impact may be caused by a sudden force applied to one or more points on the apparatus housing or another part of the apparatus accessible from outside the apparatus housing. An impact detector outputs to an apparatus controller an impact report including impact time and impact data corresponding to the detected impact event.

An image forming apparatus is provided. the apparatus comprises a sheet feeding unit to supply a plurality of types of sheets; an image forming unit to form an image on a sheet; a detection unit to detect an image formed on the sheet; and a controller that causes correction information for each sheet type to be saved in a storage, and under set conditions, causes a specified type of sheet to be supplied by the sheet feeding unit, causes a chart for gradation correction to be formed by the image forming unit, and causes the correction information to be generated based on image information for which the formed chart for gradation correction was detected by the detection unit, and saves the correction information in the storage.

An inspection device includes an image reader that generates a scan image, an inspector that inspects an inspection target image formed on a storage medium, by comparing a scan image with a reference image, a storage that stores the reference image, and a hardware processor that stores into the storage the reference image generated as the scan image by reading with the image reader an image formed on a recording medium by the image former on a basis of a second print job for generating the reference image, determines whether the reference image stored in the storage satisfies a predetermined condition when a data amount of the reference image stored in the storage becomes equal to or larger than a predetermined amount, and deletes the reference image determined to satisfy the predetermined condition from the storage.

A communication method is provided between a chip and an imaging device. Accordingly, the chip receives a clock pulse signal from the imaging device via a clock line; and receives a READ instruction from the imaging device via a data line. Within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data that are stored in an internal memory to the data line within different time slots, respectively, and the imaging device collects data from the data line while the chip is transmitting the master data to the data line. Further, the chip receives a WRITE instruction from the imaging device via the data line, wherein the chip receives master data sent from the imaging device, writes the master data into the memory arranged in the chip, and updates the implicit data stored in the memory.

An apparatus includes a volatile first storage and a nonvolatile second storage with a limited number of writes, and the apparatus includes a printer configured to execute printing based on image data, and a controller having one or more processors which execute instructions stored in one or more memories, the controller being configured to acquire information about a number of writes of the second storage, and switch between a first operating mode of storing the image data in the second storage and a second operating mode of storing the image data in the first storage and not storing the image data in the second storage based on the information about the number of writes.

An image processing system includes: a first processor that is mounted on an image processing apparatus including at least one of an image forming unit that performs processing of forming an image on a medium or an image scanning unit that performs processing of scanning an image on a medium; and a second processor that is mounted on a control apparatus that is connected to the image processing apparatus via a virtual leased line, and controls a part of at least one of the processing of forming an image on a medium or the processing of scanning an image on a medium performed by the image processing apparatus, in which the first processor is configured to: in a case where an event to be recorded in a log occurs in the image processing apparatus, transmit log information regarding the event to the control apparatus via the virtual leased line being connected or after connecting the virtual leased line in a case where the virtual leased line is not connected; and the second processor is configured to: in a case where the event occurs in the control apparatus, store log information regarding the event in a storage unit of the control apparatus; and store log information transmitted from the image processing apparatus via the virtual leased line in the storage unit of the control apparatus.

A print information processing system includes a terminal device, and a server. The terminal controller controls an image capturing device to capture an image representing at least part of a cassette and acquiring the captured image. The cassette accommodates print medium therein. A server storage stores information concerning a specific content including at least one of print data and information available for editing the print data. The system performs a detection process detecting the cassette by analyzing the captured image and a determination process determining whether the detected cassette satisfies a specific condition. The server controller performs an information transmission process transmitting the information concerning the specific content to the terminal device in a case where the determination process determines that the detected cassette satisfies the specific condition. The information transmission process is not performed in a case where the detected cassette does not satisfy the specific condition.
