A system and method for automatically scanning a physical document and performing processing actions on the scanned document are provided. The system may include a scanning device that can detect a trigger event when a portable memory device is connected to or paired with the device or when a document, including one or multiple pages, is placed on the document handler of the device. Upon detecting the trigger event, the scanning device may retrieve scan instructions from a designated folder on the portable memory device, automatically scan the document on the document handler, and perform various processing actions on the digital document file for the scanned document based on the scan instructions, with little or no user interaction. The processing actions may include storing, faxing, emailing the scanned document. The instructions for each processing action may be stored at one of multiple designated folders of the portable memory device.

To enable remote maintenance of a print control apparatus and an image forming apparatus (an image processing apparatus) to be performed by a terminal apparatus, the image forming apparatus connects to a server apparatus that relays communication between the print control apparatus and the terminal apparatus, and establishes VNC communication with the print control apparatus via the server apparatus and VNC communication with the terminal apparatus. The print control apparatus notifies the image forming apparatus that the print control apparatus will restart when instructed to restart by the terminal apparatus while the remote maintenance by the terminal apparatus is continuing. The print control apparatus instructs the image forming apparatus to reconnect to the server apparatus when the restart of the print control apparatus completes.

An image forming apparatus includes: a display portion; an error sensor that detects an operating error; a recovery sensor that detects the recovery from an operating error; and a display processor that makes the display portion display a notice of an operating error when the error sensor detects the operating error and that makes the display portion display an operation guide for preventing the reoccurrence of the same operating error when the recovery sensor detects the recovery from the operating error.

An image reading device reads an image of an original document and includes a conveyance roller, an image reading section, a first determination section, a second determination section, and a conveyance stopping section. The conveyance roller conveys the original document. The image reading section reads the image of the original document. The first determination section determines whether or not the original document has a punched hole based on the image read by the image reading section. The second determination section determines, upon determination that the original document has the punched hole, whether or not the punched hole is to travel on an edge of the conveyance roller. The conveyance stopping section stops conveyance of the original document upon determination that the punched hole is to travel on the edge of the conveyance roller.

An image processing apparatus operable to generate data for printing an image onto a printing medium using a plurality of color materials. The apparatus generates a plurality of color image data corresponding to the plurality of color materials based on image data; generates multinary color data corresponding to a combination of the plurality of color materials based on the plurality of color image data; and generates quantized data corresponding to each of the plurality of color materials based on the multinary color data and a threshold matrix. The apparatus generates the quantized data such that a color difference between a generated color in a case where a shift in a relative printing position does not occur and a generated color in a case where a shift in a relative printing position occurs is small.

Provided is an image reading apparatus, including: a reader comprising a light source upstream of an image reading position and a light source downstream of the image reading position in a moving direction, each light sources sequentially irradiating an original with light of different colors, the reader reading an original image at the image reading position while moving each light sources relatively to the original in the moving direction; a controller controlling the reading of the original image by the reader by setting a light amount ratio of the light source arranged on the upstream side to the light source arranged on the downstream side for a particular color of the different colors to be different from a light amount ratio for another color; and a detector detecting an image pattern of the particular color depending on the light amount ratio from the original image read by the reader.

An image forming apparatus which can prevent from automatically deleting, without user's intention, a box document restored from another image forming apparatus. A document storage deadline is set with respect to a folder thereof for storing box documents so as to set, as a target to be deleted from the folder, a box document having been stored in the folder over the document storage deadline. When it is determined that one of the box documents stored in the folder is a restored document, the one of the box documents is controlled to be excluded from the target.

An image reading apparatus includes a line sensor configured to read an image of a target object. The line sensor includes light receiving element arrays arranged at given intervals in a second direction perpendicular to a first direction for a plurality of lines, the plurality of light receiving element arrays each including a first light receiving element configured to receive light of a first color and a second light receiving element configured to receive light of a second color different from the first color, which are arranged in the first direction to form one line. The image reading apparatus is configured to derive a shading correction coefficient for shading correction based on output from the light receiving element arrays that have read a reference white plate, and to identify, as an abnormal pixel, a pixel obtained by reading a foreign matter existing on the reference white plate.

Provided is an image reading apparatus including: a line sensor including three light receiving element arrays arranged at a predetermined interval in a sub-scanning direction, and being configured to read an image of an original by the respective light receiving element arrays to generate read data representing the read image, the three light receiving element arrays each including light receiving elements for receiving red light, blue light and green light. These elements are arranged in a main scanning direction; and a reading control board. The reading control board is configured to acquire the read data obtained by the respective light receiving element arrays from the line sensor, to sort a plurality of pieces of read data for every pixel of the same color, and to detect an abnormal pixel that does not exist in the image of the original for each color.

A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes executing a defect learning routine to identify defects, cataloging the defects based on a job function, a type of paper, and a machine state, receiving a job request, determining a known defect that has been catalogued based on the job function, the type of paper, and the machine state, and presenting a visualization of the known defect on a display of a user interface before executing the job request.
