  • Patent number: 9056475
    Abstract: An inkjet printer includes: (a) a pagewidth inkjet printhead having a plurality of nozzles for delivering ink onto print media fed past the printhead; and (b) a maintenance assembly for maintaining the printhead. The maintenance assembly includes: (i) an elongate web of material; (ii) rollers for supporting the web; (iii) a maintenance member positioned opposite the printhead; (iv) a web-feeding mechanism for advancing the web past the printhead; and (v) an actuating mechanism for configuring the printer in either one of a maintenance position and a printing position. A gap is defined between the web and the printhead in the printing position.

  • Publication number: 20080153698
    Abstract: The present invention provides an image processing method which includes any one of recording an image on a thermally reversible recording medium that can reversibly change any one of its transparency and color tone depending on temperature by irradiating and heating the thermally reversible recording medium with a laser beam, and erasing the image recorded on the thermally reversible recording medium by heating the thermally reversible recording medium, wherein in any one of the image recording and the image erasing, the thermally reversible recording medium is located at a position farther than a focal position of the laser beam, and at least any one of the image recording and the image erasing is performed.

  • Patent number: 6532125
    Abstract: The invention discloses novel apparatus/methodology for writing/erasing high-density data on a digital recording media. A preferred embodiment of the invention features a novel thermal near-field heater that may be employed in the apparatus, particularly for realizing the methodology in a substantially thermal near-field mode. The invention provides advantages of data storage densities greater than that of diffraction limited systems, for example, data storage densities of approximately greater than 100 Gbit/inch2, and writing speeds approximately greater than 100 MHz.
