Номер: US20120001984A1
Автор: Kengo Takeda, Kenichi Hirata
Принадлежит: Brother Industries Ltd

An inkjet recording apparatus includes a record head having an ejection surface and a conveyance mechanism having a conveyance surface which passes through a position facing the ejection surface. The inkjet recording apparatus further includes: a capping mechanism which has a annular component provided around the record head to circumscribe the record head and is able to achieve capping such that the ejection surface is covered with the conveyance surface and the annular component as the annular component is caused to contact the conveyance surface; a recognition unit which recognizes a position of a first region on the conveyance surface, the first region being not smaller than an enclosed range on the conveyance surface which range is circumscribed by the annular component and being a region in which a predetermined amount or less ink adheres to an arbitrary range which is within the first region and is identical in size with the enclosed range; and a control unit which controls the capping mechanism and the conveyance mechanism so that the capping is achieved in such a way that the first region of the conveyance surface recognized by the recognition unit contacts the annular component.

Номер: US20120107032A1
Автор: Adam A. Gierczak, Barry K. Ayash, Kevin St. Martin, Michael E. Farrell
Принадлежит: Xerox Corp

An apparatus and associated method move a web of “input continuous media” along at least one media path of a continuous printing device. The method prints markings on the input continuous media to create a web of “printed continuous media” using at least one printing engine of the continuous printing device. The method holds the printed continuous media on at least one output media roll of the continuous printing device after printing the markings on the input continuous media. The output media roll is supported by an output media roll support. The method also determines when the output media roll comprises a “completed printed roll” of printed continuous media and is ready to be cut by a cutter of the continuous printing device, and the output media roll is ready to be removed from the output media roll support. If the output media roll comprises a completed printed roll, the method prints at least two copies of an “index of items” that were printed on the completed printed roll using the printing engine as the last item printed on the completed printed roll before the cutter cuts the printed continuous media is supplied to the completed printed roll and before the completed printed roll is removed from the output media roll support. The index of items is visible from the exterior of the completed printed roll after the completed printed roll is removed from the output media roll support.

Here, the plurality of image sensors are provided on the carriage at least at two positions with at least the recording element array diagonally put between the two positions. The plurality of image sensors can image the sheet at two positions separated in a main scan direction and a sub-scan direction. 1. A printing apparatus , comprising:a conveying mechanism which moves a sheet in a sub-scan direction;a printing unit which performs printing on the sheet, the printing unit holding a print head in which a recording element array is formed, the printing unit including a carriage reciprocating along a main scan direction intersecting the sub-scan direction; anda direct sensor unit including a plurality of image sensors for imaging the sheet, the direct sensor unit performing signal processing of outputs of the image sensors to detect a movement of the sheet,wherein the plurality of image sensors are provided on the carriage at least at two positions with at least the recording element array diagonally put between the two positions.211-. (canceled) 1. Field of the InventionThe present invention relates to a printing apparatus, for example to an ink jet printing apparatus which prints by discharging a liquid such as ink.2. Description of the Related ArtIn ink jet printing apparatuses, to realize a high-quality image, a high conveyance accuracy of a sheet-like printing media (in the present specification, simply referred to as a “sheet”) is required. Recently, to control conveyance with a higher degree of accuracy, direct sensors are being realized which directly detect a movement amount of the sheet by imaging the sheet surface and then performing image processing. For example, U.S. Pat. No. 7,104,710 discusses a technique for controlling conveyance ...
