摘要： A method of printing with an ink jet printer compensates for skewed printing on a print medium. An image area (12) is defined on the print medium (14) which has a plurality of rows (20) of pixel locations and a plurality of columns (22) of pixel locations. A printhead (10) includes a plurality of vertically adjacent ink emitting orifices (18) arranged in an array having a height. The printhead is scanned during first and second scans across the print medium (14) in directions (24) transverse to the advance direction (16). The ink is jetted onto the print medium (14) from the ink emitting orifices during the first and second scans at selected ink dot placement locations generally corresponding to one of the columns (20) of pixel locations. An offset is determined in a transverse direction (24) between a bottom ink dot placement location associated with the first scan and a top ink dot placement location associated with the second scan. The array of ink emitting orifices (18) is segmented into at least two vertically adjacent segments of ink emitting orifices. The ink dot placement locations associated with at least one of the segments is shifted in a direction (24) transverse to the advance direction (16) a distance which is dependent upon the determined offset. The ink dot placement locations associated with at least one other of the segments remains unchanged. Printing on the print medium is carried out using the shifted ink dot placement locations.

摘要： A heater chip module is provided comprising a carrier adapted to be secured to an ink-filled container, at least one heater chip having a base coupled to the carrier, and at least one nozzle plate coupled to the heater chip. The carrier includes a support section provided with two or more channels which define paths for ink to travel from the container to the heater chip. The heater chip is secured at its base to the support section. Carrier material located between the channels define ribs which provide a path for energy in the form of heat to travel from the heater chip to the carrier. A flexible circuit is coupled to the heater chip module such as by TAB bonding or wire bonding.

摘要： A method informs a user of an ink jet printer of the end of life of a consumable. The consumable supplies ink to a printhead having a plurality of ink ejection nozzles and an associated plurality of ink jetting actuators, each of the plurality of ink jetting actuators being addressable. The printhead includes a plurality of address lines for facilitating selection of one or more of the plurality of ink jetting actuators. The method includes the steps of defining a notice threshold that is associated with a corresponding amount of ink remaining in the consumable; providing control logic for selectively controlling the plurality of address lines; determining whether the amount of ink remaining in the consumable has reached the notice threshold; and upon reaching the notice threshold, reducing an image density of images formed by the printhead by selectively disabling at least one of the plurality of address lines.

摘要： A licensing method includes the steps of establishing a licensing vendor; providing an imaging device that uses an imaging media in forming printed images on print media, the imaging media including an initial supply amount of an imaging substance; associating a usage license with at least one of the imaging device and the imaging media, the usage license defining a first usa ge threshold at which a consumer is prompted to acquire a new license; and providing a license monitoring mechanism communicatively coupled with the imaging device, the license monitoring mechanism performing the steps of tracking an amount of usage of the imaging media by the imaging device; determining whether the amount of usage of the imaging media by the imaging device has reached a usage threshold; and upon reaching the usage threshold, then prompting the consumer to acquire the new license from the licensing vendor.
