摘要： A reading device includes: plural transport rolls that transport a document along a transport path, include a discharge roll disposed on a most downstream side of the transport path, and rotate and do not rotate in synchronization with one another; an opening and closing unit that exposes or covers an upstream portion of the transport path; plural detectors that are provided apart from one another along the transport path, detect a transported document, and include a discharge detector that is disposed on a most downstream side of the transport path and is disposed on an upstream side relative to the discharge roll in a document transport direction; a reader that reads an image formed on a transported document in a downstream portion of the transport path; and a controller that stops the plural transport rolls once upon occurrence of a document jam inside a device body by controlling the transport rolls and rotates the transport rolls for only a predetermined period in a case where the discharge detector is detecting no document and a length of a document is equal to or longer than a threshold length.

摘要： A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars (160, 190) distributed along a media transport. A first image including a reference pattern (240A, 240B) is generated on a print medium (150) with a first printbar (160). A detector (180) then detects a pattern on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar (190). This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

摘要： An image reading apparatus includes a first body, a sheet conveyance portion, an opening/closing member, a first image reading portion, and an adjustor portion. The sheet conveyance portion is configured to convey a sheet toward a sheet conveyance path. The opening/closing member is provided openably with respect to the first body and is configured to open a part of the sheet conveyance path in response to its opening. The first image reading portion is configured to read an image of the sheet conveyed by the sheet conveyance portion. The adjustor portion is configured to adjust a position of the first image reading portion.

摘要： A control apparatus includes a storing unit, a determining unit, a first notification unit, a selection unit, and a second notification unit. The storing unit stores attribute information of sheets to be stored in sheet holding units. The determining unit determines whether attribute information of sheets to be used by a job corresponds to the stored sheet attribute information. The first notification unit notifies, in a case where the determining unit determines that the attribute information does not correspond, a user that the attribute information does not correspond to the sheet attribute information. The selection unit selects the stored sheet attribute information to change the attribute information of sheets to be used by the job. The second notification unit notifies, in accordance with selection of the sheet attribute information, the user that the attribute information of sheets to be used by the job corresponds to the stored sheet attribute information.

摘要： An image processing apparatus comprises a scanner section and an area determination section. The scanner section reads the light reflected from an original document after the light penetrates a light diffusion sheet to output first image data, wherein the light diffusion sheet has a surface for diffusing the light reflected from the original document including a mirror reflection area; and the area determination section determines the mirror reflection area with respect to the first image data output from the scanner section.

摘要： Based on attachment position information of each of a plurality of sensor units, which reads an image in each area obtained by dividing the area of an original in a sub-scanning direction, image data output from the sensor unit undergoes attachment error correction of correcting the attachment error of the sensor unit. Image data output from the plurality of sensor units then undergo joint processing. Based on the placement information of the original, tilt correction of correcting the tilt of the original is performed for the image data having undergone the joint processing.
