An image reader wherein a controller executes: a start process of starting a reading operation; a head edge detection process of detecting a document width; a first side edge detection process of detecting a side edge until an occurrence of a first change from a side edge detecting state to a side edge non-detecting state; a calculation process of calculating a continuation distance based on the document width; a second side edge detection process of detecting the side edge until an occurrence of a second change from the non-detecting state to the detecting state; a third side edge detection process of detecting the side edge until an occurrence of the first change; and an end process of ending the reading operation when the second change does not occur in a continuation range in the second detection process or when the first change occurs in the third detection process.

A printing apparatus capable of adding number information differing from copy set to copy set, to a printing target image includes a judging unit configured to judge whether to add user information indicating a current user to a printing target image, and a determination unit configured to determine a position to which the number information is to be added, based on a result of the judgment performed by the judging unit.

A printing apparatus capable of adding information to a printing target image includes an addition unit configured to add the information, a setting unit configured to set an area to which the information is added based on a user operation, a specification unit configured to specify a length of a sheet used for printing in a sheet conveyance direction, and a control unit configured to control, in a case where the length of the sheet in the sheet conveyance direction is not specified, the addition unit to add the information into a leading end side area in the sheet conveyance direction even if a trailing end side area is set by the setting unit as the area to which the information is added.

An image processing device includes: a fold unit that folds an adjustment sheet, in which an adjustment pattern including at least one line segment is formed, over the at least one line segment based on a predetermined reference fold position; an image reader that reads an image of the adjustment pattern of the adjustment sheet with the adjustment sheet folded by the fold unit unfolded; a position identifying unit that identifies, as a position of a fold line, a position of distortion of the at least one line segment or a predetermined position of an area which appears in the image of the adjustment pattern read by the image reader; and a fold position adjusting unit that adjusts a fold position of the fold unit based on a difference between the position of the fold line identified by the position identifying unit and the reference fold position.

An image reading device includes an original document transport device, a first reading module and a control portion. When the control portion performs the light source turning-on confirmation processing of the first reading module, the control portion performs first opening/closing determination processing for determining the state of the opening and closing of a cover member, light amount acquisition processing for turning on a light source so as to acquire light amount data after it is determined in the first opening/closing determination processing that the cover member is in a closed state, second opening/closing determination processing for determining again the state of the opening and closing of the cover member after the acquisition of the light amount data in the light amount acquisition processing and light amount determination processing for determining the light amount after it is determined that the cover member is in the closed state.

An information processing apparatus includes circuitry configured to set a blank page handling feature, detect a blank page/blank pages in a document of a print job, and handle the detected blank page/blank pages in the document based on the set blank page handling feature.

A printer includes: a processor; a head configured to perform printing; a sensor configured to detect an amount of movement of the printer; and a scanner configured to acquire an image including a frame described on a material to be printed beforehand, the scanner being disposed forward of the head in a moving direction of the printer. The processor executes during scanning for frame detection over the material to be printed, frame detection processing to detect the frame based on the amount of movement and the image without performing the printing, and during scanning for printing over the material to be printed, print processing to perform the printing with the head based on the frame detected.

An image scanning device includes a platen, an image scanning unit that scans at a single time documents placed on the platen and generates pieces of image data, and an image data processing unit that performs processing of the pieces of image data. When the image scanning unit generates pieces of first image data by scanning first surfaces of the documents, each of which is placed in one of predetermined areas on the platen, and generates pieces of second image data by scanning surfaces opposite to the first surfaces of the documents, each of which is turned over and placed again in the one of the predetermined areas, the image data processing unit associates one of the pieces of the first image data with a corresponding one of the pieces of the second image data for each of the predetermined areas, as image data of the front and back surfaces.

According to examples, an apparatus may include a processor and a memory on which are stored computer-readable instructions that, when executed by the processor, may cause the processor to identify first property values along an image of a pattern. The first property values may be identified based on a first signal corresponding to an image of the pattern captured by an imaging sensor. The pattern may be positioned at a spaced relation with respect to the imaging sensor. The processor may receive a second signal corresponding to a second image captured by the imaging sensor, and may identify, from the second signal, second property values along the second image. Based on a determination that the second property values differ from the first property values, the processor may determine that a beginning of a media is positioned to be imaged by the imaging sensor.

An image forming apparatus includes a scanner and a printing apparatus, wherein the scanner includes a scanning window; a transport unit configured to transport a document to a top surface of the scanning window; a scan unit configured to obliquely irradiate light to a bottom surface of the scanning window to scan the document; a transport guide member configured to be disposed to face the top surface of the scanning window to guide a transport of the document; and a curved reflection member configured to be coupled to the transport guide member to collect the light irradiated from the scan unit and to reflect the collected light toward the scanning window.
