Patent number: 6749280Abstract: Coordinates in an image and its corresponding color-converted data are supplied to a control/operation portion for every pixel. Quantization is applied to each color. The quantization is carried out so that a kind of dot for at least one color is made different from kinds of dots for the others in one and the same pixel when dots for different colors are superimposed on the pixel. The control/operation portion refers to a two-dimensional matrix on the basis of the quantization result, determines an output dot for each color, and converts the data into data which can be processed by a printer. The printer records an image based on the quantization result while reciprocating a recording head. Thus, it is possible to reduce color shift caused by the difference of the ink landing order at the time of reciprocating the head for recording.Type: GrantFiled: December 13, 2002Date of Patent: June 15, 2004Assignee: Fuji Xerox Co., Ltd.Inventors: Tohru Shimizu, Daisuke Tatsumi

Patent number: 6749282Abstract: In an inkjet printer having primary power-turn-on means for physically supplying power to the printer and secondary power-turn-on means for bringing the printer into a state where functions are enabled, ink consumption due to a suction recovery processing is reduced. The number of times that the secondary power supply is on is counted. The count value is stored in a non-volatile memory. It is judged whether the count value is above a predetermined value when the secondary power supply becomes on, if yes, the recovery processing is executed. The count value and the contents of the memory are then cleared. The counting is prohibited till primary power supply is off. As the above contents is retained even after the primary power supply is off, necessity of recovery processing when the secondary power supply becomes on is judged based on the state before the primary power supply was off.Type: GrantFiled: February 22, 2001Date of Patent: June 15, 2004Assignee: Canon Kabushiki KaishaInventor: Tetsushi Kohno

Patent number: 6749284Abstract: When a printing apparatus performs printing using dark and light inks, a large variation in density caused by a rapid decrease in ink applying rate is prevented, thereby enabling proper density reproduction. More specifically, when for example, green hues of different densities are printed, light cyan ink is used between points corresponding to a variation of color from white to green. Furthermore, after the maximum saturation point, light cyan ink is used in addition to the dark cyan ink. This prevents the total applying rate from decreasing rapidly near the maximum eaturation point.Type: GrantFiled: July 31, 2002Date of Patent: June 15, 2004Assignee: Canon Kabushiki KaishaInventors: Shigeyasu Nagoshi, Okinori Tsuchiya

Patent number: 6749291Abstract: An inkjet head selectively ejects recording ink droplets and refresh ink droplets. The recording ink droplets are deflected so as to impinge on target locations on a recording medium, thereby forming recording dots thereon. On the other hand, the refresh ink droplets are deflected so as to impinge on an ink absorbing member. The ink clinging on the ink absorbing member is collected into an ink tank and reused. The ink absorbing member functions as a filter for preventing impurities being collected into the ink tank along with the ink.Type: GrantFiled: April 3, 2003Date of Patent: June 15, 2004Assignee: Hitachi Printing Solutions, Ltd.Inventors: Kunio Satou, Takahiro Yamada, Hitoshi Kida, Akemi Ouchi, Tsutomu Maekawa, Hidetoshi Fujii

Patent number: 6749292Abstract: The present disclosure relates to an ink container to be received within a receiving station of an inkjet printing system. The receiving station has a fluid inlet having a compliant seal and a pair of guide slots extending along either side of the fluid inlet. The ink container includes a guide feature outwardly extending therefrom. The guide feature is disposed toward a trailing end relative to an insertion direction. The guide feature is configured to cooperate with the at least one guide slot to guide the ink container in a pivot motion to ensure the ink container engages the compliant seal forming a seal therewith.Type: GrantFiled: October 18, 2001Date of Patent: June 15, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott D. Sturgeon, Curt G. Gonzales

Patent number: 6749293Abstract: An ink cartridge having a one-piece housing including a plurality of walls to form a chamber for receiving ink. The housing is formed of a blow-molded plastic material. An outlet passage extends from a bottom wall communicating with the chamber. A seal and cap assembly are secured to the outlet passage. A vent opening is provided in a top wall. The vent includes a porous member and a cap to secure the porous member within the vent. The housing is fully filled with ink. The housing allows for the use of pigmented ink since no reservoir is provided.Type: GrantFiled: June 13, 2002Date of Patent: June 15, 2004Assignee: Nu-kote International, Inc.Inventor: Bruce S. Jones

Patent number: 6749294Abstract: An inkjet printer and inkjet print cartridge are each especially configured for inter-engaging with one another via a plurality of keying features of the cartridge and keying structures of the printer such that loading of a foreign print cartridge into the printer is either not possible or results in the printer being inoperative. Thus, only print cartridges particularly configured and intended to be used in the printer will fit into and enable its operation.Type: GrantFiled: October 10, 2002Date of Patent: June 15, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventor: Tom Haldorsen

Patent number: 6749295Abstract: An ink-jet cartridge includes a cartridge body forming an ink reservoir, a standpipe coupled to one side of the ink reservoir, a printhead formed under an ink supply passage formed by the standpipe, through which ink from the ink reservoir is ejected onto a printing medium in a droplet shape, and a filter which covers a top portion of the standpipe. The filter is formed in a convex shape protruding toward the printhead. Ink particles and bubbles flowing from the ink reservoir to the printhead are filtered out, bubbles which may flow from the printhead to the ink reservoir, move to edges of the filter, and the ink is smoothly supplied to the printhead.Type: GrantFiled: December 30, 2002Date of Patent: June 15, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Moo-youl Kim, Seo-hyun Cho, Hyung-hyu Hwang, Myung-song Jung, Jae-cheol Lee, Young-su Lee

Patent number: 6749298Abstract: A printing system includes a media transport assembly adapted to route media through a media path of the printing system, a motor adapted to drive the media transport assembly, and a power transmission arrangement operatively coupling the motor with the media transport assembly. The media transport assembly includes a pick assembly adapted to draw the media into the media path and a feed assembly adapted to feed the media through the media path. A portion of the power transmission arrangement is adapted to rotate in a first direction to couple the motor with the pick assembly and the feed assembly and rotate in a second direction opposite the first direction to couple the motor with the feed assembly and decouple the motor from the pick assembly.Type: GrantFiled: February 27, 2003Date of Patent: June 15, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Wesley Ryan Schalk, Allan G. Olson

Patent number: 6749300Abstract: The invention describes a capillary optical element with a complex structure of capillaries and a method for its manufacture. To achieve uniform transmission, for example, a lens can be used as a capillary optical element which has a complex structure with channels of different diameter. The channels with the smaller diameter operate effectively at higher energies, channels with intermediate diameters are intended for an intermediate energy range, whereas channels with a large diameter are used in a low energy range. A lens can consist, for example, of three zones: channels with small diameter are used in the central zone, channels with intermediate diameters are used in the intermediate annular zone, and the peripheral zone has channels of large diameters. The number of zones can arbitrary. In addition, a technical process for manufacturing the complex capillary structures is described.Type: GrantFiled: March 12, 2002Date of Patent: June 15, 2004Assignee: IFG Institut für Gerätebau GmbHInventor: Aniouar Bjeoumikhov
