An image processing device includes an association unit, a generation unit, an output unit, a reception unit, and a print unit. The association unit associates a first document image with a second image, the second image being an image of a reverse side of the first document image. The generation unit generates multiple images in accordance with a result of the association. The output unit outputs the multiple images generated by the generation unit. The reception unit receives a selection of an image output by the output unit, the selection being made by a user operation. The print unit prints the selected image.

An image forming apparatus according to an embodiment includes a paper supply unit. An image forming unit forms an image on paper supplied from the paper supply unit. A reading unit generates image information by reading an original document, the generated image information corresponding to the original document. An input unit receives input designation of a memo region in the generated image information. A control unit determines a color of the original document based on the generated image information. The image forming unit forms a memo image in the designated memo region on the paper supplied from the paper supply unit with a color different from the determined color of the original document.

An image reading device includes first glass, an adjacent portion adjacent to the first glass, a reading unit, and a position reference portion. The first glass enables an document to be placed on a front surface side of the document. The reading unit is capable of being in contact with at least one of the adjacent portion and the first glass and reads, from a back surface side of the first glass, the document placed on the first glass by using a sensor while moving from the adjacent portion side in a movement direction. The position reference portion is disposed on the front surface side of the first glass and serves as a reference of a position of the reading unit in the movement direction. When the position reference portion is read by the reading unit, the reading unit is in contact with the adjacent portion and the first glass.

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.

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.

In one aspect, the present disclosure provides a printer including a controller that controls a printing unit, the controller executing: a movement distance measuring process that measures a movement distance of the printing unit relative to a printing medium; a coordinate recording process that calculates a plurality of coordinates on the basis of the movement distance measured in the movement distance measuring process; a printing region setting process that sets a printing region on the basis of the plurality of the coordinates recorded in a memory in the coordinate recording process; and a printing image selection process that identifies an image that has the largest area from at least one image, the at least one image being extracted from a group of images pre-recorded in the storage unit by designating such images that fit within the printing region set by the printing region setting process.

An image forming apparatus, including: a light source including a plurality of light emitting points and configured to emit light beams; a photosensitive member configured to rotate in a rotation direction so that a latent image is formed thereon with the light beams; a rotary polygon mirror configured to rotate around a rotation axis and having a plurality of mirror faces each configured to deflect the light beams so that the photosensitive member is scanned with the light beams; a detector configured to detect temperature; and a correction unit configured to correct image data of an input image by using a deviation amount, in the rotation direction of the photosensitive member, of the light beams deflected by each of the plurality of mirror faces, wherein the correction unit obtains the deviation amount according to the temperature detected by the detector.

An image reading device includes: an image reading unit configured to, in a process of reciprocating relative to a fixed document, read a document image using one or a plurality of reading colors, and when a plurality of reading colors are used, read the document image while successively switching the reading colors in a process of moving; a moving unit configured to move the image reading unit; a moving speed changing unit configured to change moving speeds of the image reading unit in an outgoing path and a return path based on a number “N” (where N is a positive integer) of the reading colors by the image reading unit; and a reading color number changing unit configured to change reading color numbers of the image reading unit in the outgoing path and the return path based on the number “N” of the reading colors.

An information processing apparatus includes a receiving unit that receives print instruction information; an authenticating unit that performs an authentication for permitting a printing process; an execution unit that executes the printing process when the authentication succeeds; a near field communication unit; a wireless communication unit that performs wireless communication that differs in a communication protocol from the near field communication; a transmitting unit that transmits identification information of the information processing apparatus to a terminal device when a connection via the near field communication is established in response to an operation of passing the terminal device over the near field communication unit; and a control unit that, when the receiving unit receives the print instruction information via the wireless communication using the identification information as a transmission destination, temporarily disables a function of the authenticating unit, and causes the execution unit to execute the printing process.
