摘要： Provided herein is a printing apparatus including a printhead movable between a first position and a second position. The printhead includes a first substrate and a second substrate. The first substrate and the second substrate define at least a first burn line and a second burn line, respectively, of heating elements disposed adjacent to a first edge and a second edge, respectively of the printhead. A printhead bracket receives the printhead in one of the first position or the second position. In the first position, the heating elements of the first burn line perform a printing operation and the printhead bracket is configured to preclude operation of the heating elements of the second burn line. In the second position, the heating elements of the second burn line perform a printing operation, and the printhead bracket is configured to preclude operation of the heating elements of the first burn line.

摘要： A method for controlling a thermal printhead of a printer. The printhead comprises an array of printing elements. The method may comprise performing a plurality of printing operations, each printing operation comprising energization of one or more printing elements. A respective energization value is determined for each printing element based upon energizations of that printing element during said printing operations. A printhead control signal is generated for the printhead for a subsequent printing operation based upon the energization values of a predetermined subset of the printing elements.

摘要： A method of heating a print zone disposed between a print-head and a media support device of a printing system includes supplying a first amount of power to a heating assembly to form and direct heated air in a first temperature range to the print zone of the printing system. The method also includes determining whether a temperature of the printhead is within a warning temperature range and, if so, supplying a second amount of power that is less than the first amount of power to the heating assembly to form and direct heated air in a second temperature range to the print zone. Otherwise, the first amount of power is continued to be supplied to the heating assembly.

摘要： A device for erasing an image on a sheet includes a reading unit that reads an image formed on a sheet. An erasing unit erases the image formed on the sheet by heating the sheet after the sheet has passed through the reading unit. A conveyance path conveys the sheet from the erasing unit back to the reading unit. The conveyance path includes a curved portion between the erasing unit and the reading unit. A cooling unit cools the sheet which passes through the conveyance path. The cooling unit includes at least one fan that supplies cooling air generally along a sheet conveying direction. A rate of the cooling air supplied to an outer peripheral portion of the curved portion of the conveyance path is larger than a rate of the cooling air supplied to an inner peripheral portion of the curved portion of the conveyance path.

摘要： There is described an image forming apparatus, which forms high quality images free from a phenomenon of inter-sheet adhesion. The image forming apparatus includes a conveyance section to convey the transfer material along a conveying path; a cooling device disposed along the conveying path to cool the transfer material just after the toner image is fixed with heat; a controller-to control the conveyance section and the cooling device; and a first transfer-material detecting device disposed at a position adjacent to and upstream from the cooling device, in order to detect the transfer material coming into the conveying path. When the first transfer-material detecting device detects the transfer material coming, the controller controls the conveyance section to decelerate a conveyance velocity of the transfer material to a decelerated velocity lower than a normal conveyance velocity, so that the transfer material passes through the conveying path at the decelerated velocity.

摘要： A reversible thermal recording method using a color/non-color type reversible thermosensitive recording material which has a recording layer formed overlying at least one side of a substrate and including an electron donating coloring agent and an electron accepting color developer and which reversibly forms a colored state and a non-colored state by being appropriately heated and cooled. The recording layer having images of the colored state which have been formed in the recording layer is heated to erase the image, and imagewise heated either at substantially the same time as, or after, the image erasing operation to record new images therein, and then relatively rapidly cooled to maintain the new images. A reversible thermal recording apparatus therefor is also provided.

摘要： A laser printer produces an image of raster scan lines exhibiting a pitch distance p. The printer includes a photoreceptor and n laser sources, where n.gtoreq.2. First and second sets of laser sources, in one embodiment, produce plural optical beams which, when imaged on the photoreceptor, are separated by pitch distance p in the direction of movement of the photoreceptor. The first set and second sets of laser sources are separated by a distance S.sub.PR =c(1+qr)p, where: c=number of laser sources in each set, q=an integer, and r=number of rows of laser sources in both the first and second sets. The optical beams are modulated with pixel value data in accordance with a correspondence of image scan lines and positions of the optical beams on the photoreceptor. The photoreceptor is moved by a distance (q.multidot.c.multidot.r)p between scans. In such manner, an interleaving of the scan lines is achieved, which allows substantial separation of laser diodes on a laser diode chip.
