摘要： A printer is provided wherein printing can be executed continuously after the rear end of printing paper comes off a paper feeding roller without loss in print image quality. Specifically, the position of a point nipped by a paper ejecting roller is placed higher than the position of the top face of a record medium regulating part, and the surface of the paper located upstream of the paper ejecting roller is pressed downward. The position of the top face of the record medium regulating may be varied and backed up. As a result, the rear end of the paper being pressed downward may be caused not to touch the print head. The printer is also provided with a driving controller, that executes an interlace recording method, and the end on the upstream side of the flat top face of the record medium regulating part is located within a range of the array of dot formation elements. The drive controller records a first line of a record object using dot formation elements located at the rear end of the recording head, after the front end of the record medium reaches the end on the upstream side of the top face of the record medium regulating part and is therefore properly positioned. Subsequently, the interlace recording method is executed by repeating sub scanning, by a predetermined sub scanning distance, and main scanning by the recording head.

摘要： An image formation apparatus is provided having a continuous form photosensitive member positioned to move along a pre-defined transfer path. An image is exposed on to a portion of the photosensitive member along the transfer path. A heat developer heats the exposed image portion and intercepts the heat to an unexposed portion of the photosensitive member. The heat developer has a cylindrical housing having a heated portion arranged along a longitudinal axis of the cylindrical housing and a heating element in surface contact with and for heating exposed portions of the photosensitive member. The cylindrical housing also has an unheated portion arranged along the longitudinal axis of the cylindrical housing and separated from the heated portion by a thermally insulative material. A thermal shield is selectively movable along the transfer path in synchronism with and in the direction of transfer of the photosensitive member between a heat shielding position and a non-heat shielding position for protecting and preserving unexposed portions of the photosensitive member. The thermal shield has a curved heat shield position adjacent to the heating element and movable concentrically about the longitudinal axis between the heat shielding position between the heating element and photosensitive member and the non-heat shield position.

摘要： Data is printed on a recording sheet by heating the recording sheet at a pre-printing heating region of a heat roller 20, and the recording sheet is further heated at a post-printing heating and fusing region to thereby be dried and fused. In the meantime, air introduced from an exhaust fan 50 is blown into a data writing section from bottom up in the same direction as a recording sheet feeding direction, so that not only the vapor generated from the recording sheet during the heating and the vapor generated from the ink during the printing are eliminated, but also a recording head 40 is cooled.

摘要： An ink jet printer in which hardened ink is readily and reliably removed from a nozzle plate. The ink jet printer includes a print head having a plural number of nozzle openings arrayed in the width direction of a recording paper, a head drive circuit for selectively outputting a first signal to cause a stream of ink droplets at a speed suitable for print and a second signal to cause ink to ooze through each nozzle opening, and a cleaning device with a rubbing function and which is usually positioned in a nonprinting region, but is movable in the longitudinal direction of the print head and with respect to a nozzle plate. In a cleaning mode, the cleaning device is operated while oozing ink from the nozzle openings. The hardened ink on the nozzle plate is dissolved by the oozing ink, and then removed therefrom through the rubbing and wiping operations of the cleaning device.

摘要： A cutter device includes a medium supporting surface that supports a recording medium being transported, and a cutter carriage that has a cutter blade for cutting the recording medium and that is movable in a direction perpendicular to the transport direction of the recording medium. An opening that forms a passage region for the cutter carriage is provided in the medium supporting surface so as to extend in the moving direction of the cutter carriage. The opening is provided with a cover capable of switching between a first state in which the cover covers the opening and forms part of the medium supporting surface and a second state in which the cover is retracted to form the passage region for the cutter carriage.
