    摘要: An inkjet printhead assembly (50) for an inkjet printer having a printhead (10) with a plurality of nozzles (24) and data path and control electronics circuitry (56) operably coupled with the printhead (10) for providing image data that control the flow of ink through the nozzles (24). The nozzles (24) are arranged in sections with actuators (28a, 28b) predisposed about each nozzle (24), for causing the nozzles (24) to print. Interconnections (54) between the data path and control electronics circuitry (56) and printhead (10) include DATA, CLOCK, LATCH and ENABLE lines which are used to operate the printhead (10) and, in turn, the nozzles (24) via shift register stages (228). The actuators (28a, 28b) are supported by the shift register stages (228) into which data is shifted from register stage to register stage for loading data that enables the actuators (28a, 28b). The shift registers stages (228) for all actuators (28a, 28b) are located to one side of the print head (10) to facilitate cleaning of the nozzles (24).

    摘要: An inkjet printhead assembly (50) for an inkjet printer having a printhead (10) with a plurality of nozzles (24) and data path and control electronics circuitry (56) operably coupled with the printhead (10) for providing image data that control the flow of ink through the nozzles (24). The nozzles (24) are arranged in sections with at least two heater elements, an upper heater (28a) and a lower heater (28b), predisposed about each nozzle (24), the heater elements configured to actuate a nozzle (24) for printing. The data path and control electronics circuitry (56) comprises a plurality of shift registers (100, 102) configured to drive the nozzles, causing them to deliver ink in the direction of a receiver media, such as paper. Interconnections (54) between the data path and control electronics circuitry (56) and printhead (10) include DATA, CLOCK, LATCH and ENABLE lines which are used to operate the printhead (10) and, in turn, the nozzles (24) via the shift register stages (100, 102). The number of interconnections are minimized by interleaving data to the shift registers between upper and lower heater elements of the printhead (10) or by interleaving the data on the DATA line to the shift register stages (104, 106) for the upper and lower heater elements.
