A lighting device (23) irradiates a web under conveyance with light. The lighting device includes a light source (43), and an irradiation port (61) configured to open linearly in a widthwise direction of the web at an end portion facing the web. The irradiation port (61) is formed between first and second parallel portions (62b, 63b) where a first plate member (62) and a second plate member (63) parallelly face each other. The web under conveyance is irradiated with linear light. It is possible to provide a lighting device capable of irradiating only an inspection region of a sheet or a web with light.

An image forming apparatus includes: an image forming unit configured to form an image on a sheet; a conveyance unit configured to convey the sheet having the image formed thereon to a conveyance path; a reading unit configured to read a test image of a sheet conveyed to the conveyance path; and a controller configured to: determine an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit; control the image forming unit to form the test image; control the reading unit to read the sheet having the test image formed thereon; determine an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit.

A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of lateral translations wherein the image data is laterally translated such that it is printed at a different lateral position on the printed page.

A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of page orientations including a first page orientation and a second page orientation, wherein the image data for the second page orientation is rotated 180 degrees relative to the image data for the first page orientation.

There are provided an image processing apparatus, an image processing method, and a storage medium which are capable of obtaining an image expected by a user. To this end, for an original region on an inner side, the original region is set by using a parameter corresponding to the original region on the inner side. For an original region on an outer side including an outer edge, the original region is set by using a parameter corresponding to the original region on the outer side.

A document processing system and method includes a display and an embedded controller that modifies the font used on the display based on the distance between a user and the display. When the user moves closer to the display, the font size of text displayed on the display is increased to enhance readability of the text. The font size of the text is decreased when the user moves further away from the display. The user can lock the font size of the text when the font is at an acceptable size to the user. All or a portion of the text that is displayed on the display can be dynamically resized. Different fonts also can be used to enhance readability for the user. The font also can be selected based on the user identity or user demographic information.

A method for the automated generation of reference color values for color control purposes in a printing machine by using a computer includes, within a process of setting up the printing machine for a print job, initially carrying out printing operations and using a spectrophotometer to determine coloration values for every process color used in the print job. For every process color that is used in the print job, the computer automatically selects that coloration value of a process color that has the smallest deviation from a color set point that has been established at the beginning of the job and saves this coloration value as a new reference value for this process color.

Systems, devices, and methods illuminate one or more areas on a calibration medium from a first side of the calibration medium with one or more respective light-emitting regions of a light source; detect light transmitted through the calibration medium at the one or more areas, thereby obtaining calibration-measurement information for at least one of the one or more light-emitting regions; illuminate one or more color patches on a color-measurement medium from a first side of the color-measurement medium with the one or more respective light-emitting regions of the light source; detect light transmitted through the one or more color patches printed on the color-measurement medium, thereby obtaining color-measurement information for at least one of the one or more light-emitting regions; and generate one or more transmissive measurements based on the calibration-measurement information and the color-measurement information.

A system and method for maintenance and supplying of a fleet of multifunction peripheral devices includes two or more networked devices including a decision engine. Devices discover one another and one device is designated as a server. The server creates a virtual lobby accessible by other devices and its decision engine is enabled. The server invites other devices into its virtual lobby, and these devices join the lobby in response. Devices provide their device state information to the lobby. The enabled decision engine generates recommendations for consumable replenishment, device servicing or device configuration, relaying the recommendations to a system administrator's tablet or smartphone. The administrator may accept, reject, modify or implement received suggestions. Consumable supplies or servicing recommendations can be done automatically if enabled. Administrator actions are fed back to the server for machine learning to improve future suggestions.

An image processing apparatus includes a printer that prints an image on a sheet, a scanner that reads an image on a sheet, and one or more controllers configured to cause the scanner to read an image on a sheet, to cause a display to display the image, to receive an instruction for adopting an image serving as a candidate for a correct image from the displayed image, to generate the correct image based on the image serving as the candidate, to register the correct image, and to cause the scanner to read an image printed on a sheet and to verify the printed image based on the read image and the registered correct image. When a defective image is in the read image, the display displays the defective image in which a defective area is emphasized and the defective image in which the defective area is not emphasized.
