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