Printer having a printhead assembly with shift register stages arranged for facilitating cleaning of printhead nozzles

摘要

An inkjet printhead assembly (225) for an inkjet printer having a printhead (10) with a plurality of nozzles (24) and circuitry (80) operably coupled with the printhead (10) for providing image data to actuators that control the flow of ink through the nozzles (24). The nozzles (24) are arranged in sections with the actuators (28a, 28b) predisposed about each nozzle (24), for causing the nozzles (24) to print. 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) by a cleaning assembly (280). <IMAGE>
