An image processing device includes: a hardware processor configured to: execute a process according to a received remote operation in response to reception of the remote operation from a master device registered in advance among a plurality of mobile information devices; confirm to a duplicate login device other than an own device among the plurality of image processing devices that the duplicate login device is remotely operated by the master device in a case where a remote operation of instructing connection with a sub device different from the master device is received from the master device; and execute a process according to a remote operation received from the sub device in a case where it is confirmed by a confirmation unit that the duplicate login device is remotely operated by the master device.

An image forming system capable of preserving appropriate density-gradation characteristics and color output characteristics. An image processing apparatus for executing second calibration is connected to an image forming apparatus for executing first calibration. When an instruction for executing the second calibration in succession to execution of the first calibration is received, the image processing apparatus transmits an inhibition command for inhibiting a print operation to the image forming apparatus, and shifts to an inhibition mode. The image processing apparatus transmits a cancel command for canceling inhibition of the print operation to the image forming apparatus. Even when an instruction for executing the job is received, the image processing apparatus does not transmit the job to the image forming apparatus during the inhibition mode.

An image forming apparatus connected to a charging apparatus that collects a fee includes an authentication unit that authenticates users and a display that displays a screen enabling users to select between logging into the image forming apparatus based on being authenticated or by paying a fee using the charging apparatus.

If a cartridge restriction mode is set in which execution of image formation by a predetermined cartridge is restricted when a print job is accepted, an image forming apparatus determines whether the accepted job is a specific job. Furthermore, the image forming apparatus permits execution of restricted image formation if it determines that the accepted job is the specific job.

Magnetic keys having a plurality of magnetic plates are disclosed. The location and orientation of the magnetic plates are controlled to generate magnetic fields that are of sufficient strength to be reliably read and sufficient complexity to be difficult to counterfeit. The magnetic keys are located on imaging-device supply items along with non-volatile memory devices containing measurements of the magnetic fields that are digitally signed. These supply items are difficult to counterfeit. Other devices are disclosed.

According to some embodiments, a document processing unit may receive information associated with a document to be processed. The document processing unit might comprise, for example, a printer, scanner, copier, facsimile machine, or multi-function device. The document processing unit may then automatically analyze the received information in view of at least one pre-determined document policy. The document processing unit may then automatically determine, based on the analysis, whether to apply a policy action, associated with the pre-determined document policy, to the processing of the document. For example, the document processing unit might prevent a document from printing.

An image forming apparatus that determines whether an image having coincidence with a registered image is included in an input image and controls execution of a job that uses the input image based on a result of the determination. The image forming apparatus includes an input unit that inputs a first image as a candidate of the registered image, an evaluation unit that evaluates whether the first image is suitable for use in the determination, and a control unit registers the first image as the registered image if the evaluation unit evaluates that the first image is suitable for use in the determination, and prevents the first image from being registered as the registered image if the evaluation unit evaluates that the first image is unsuitable for use in the determination.

A data processing apparatus connected to a terminal device and providing a service in response to a request from the terminal device, includes a processable condition storing unit that stores one or more services providable by the data processing apparatus and a position of a terminal device to which provision of the service is permitted in correspondence with each of the services; a receiving unit that receives a service request of requesting provision of a service and positional information of the terminal device sent from the terminal device; and a control unit that controls the data processing apparatus to provide the service requested by the service request when the position indicated by the positional information received by the receiving unit is included in the position that is in correspondence with the service requested by the service request received by the receiving unit in the processable condition storing unit.

The present disclosure discloses methods and systems for detecting one or more security patterns in a document submitted at a multi-function device. According to the disclosure the document is received at the multi-function device, wherein the document includes at least textual content. Thereafter, a pre-defined operation is performed to detect edges of the at least textual content. Once detected, one or more text edges are filtered based on one or more templates. Further, based on the one or more templates, shape and color of the filtered one or more text edges are analyzed, and accordingly, the presence of the one or more security patterns is ascertained in the submitted document at the multi-function device.

A processing apparatus includes: a processing unit that performs plural predetermined processes; a display unit; a creation unit that creates a first process receiving portion and a second process receiving portion, each of which receives an instruction to any one of the plural predetermined processes on the display unit; and an execution portion that executes the process, in a case where the instruction is received by the first process receiving portion, after receiving the instruction again, whereas, in a case where the instruction is received by the second process receiving portion, the execution portion executing the process without receiving the instruction again.
