    摘要： A printhead is provided having elongate printhead modules arranged to aggregately extend across a pagewidth and controllers for processing print data into dot data and for controlling the printhead modules in accordance with the dot data. Each printhead module has plural rows of ink ejection nozzles. The nozzle rows of at least one of the printhead modules are longer than the nozzle rows of the other printhead modules. The controllers control ink ejection of the nozzles of the printhead modules in accordance with the dot data. At least one of the controllers is arranged to control all of the printhead modules and at least one other of the controllers is arranged to control only one of the printhead modules.

    摘要： A print cartridge is disclosed. The print cartridge has at least one ink reservoir, a storage means configured to store information indicative of an amount of printing achievable by the cartridge based on the amount of ink in the at least one ink reservoir, the information being stored in the form of a plurality of bits, the storage means including a plurality of first fusible links, each of the first fusible links storing one of the bits, an information changing mechanism for changing a value of the information by selectively blow one or more of the first fusible links each time a predetermined amount of ink is consumed, and a printhead having a second fusible link which destructs the printhead in response to the value of the information reaching a predetermined threshold.

    摘要： A printer controller for supplying dot data to an inkjet printhead is provided. The printhead comprises a plurality of first nozzles and a plurality of second nozzles supplied with a same colored ink. The first nozzles and second nozzles are configured in a plurality of sets, wherein each set of nozzles comprises one first nozzle and one corresponding second nozzle. Each nozzle in a set is configurable by the printer controller to print a dot of the ink onto a substantially same position on a print medium. The printer controller is programmed to supply dot data such that the first nozzles and the second nozzles each contribute dots to a line of printing.

    摘要： A printhead system comprising an inkjet printhead and a printer controller for supplying dot data to the printhead is provided. The printhead comprises a plurality of transversely aligned color channels, each color channel comprising at least one nozzle row extending longitudinally along said printhead. Each nozzle in a color channel ejects the same colored ink. The printhead is comprised of a plurality of printhead modules with each printhead module comprising a respective segment of each nozzle row. The printer controller is programmed to supply dot data such that each of the printhead modules fires a respective segment within a predetermined segment-time. At least one of the fired segments is contained in a different color channel from at least one other of the fired segments.

    摘要： A system and method for reducing the noise induced in a particular section or level of a signal bandwidth. The section is isolated from the rest of the signal data, by resealing this data to produce a buffer section adjacent the section with little or no data in it. The signal is then transmitted to the output device where all data is the buffer section is considered to be the result of noise, and is mapped back to the predetermined level. The signal data is inversely rescaled to move data back into the buffer section. In this way, more of the data that was input at the predetermined level, will also be at the predetermined level afterwards, thereby correcting noise induced in that level by noise inducing transmission techniques such as JPEG compression.
