Abstract
A plurality of inkjet printhead elements are arranged to form a pagewide printhead array. The elements are secured to a flexible interconnect to allow for communication between the individual elements and a printer controller. The elements are arranged in the array so that one or more nozzles overlap nozzles of the two adjacent elements. The printer controller specifies the desired drivers of the heater elements to be actuated in commands sent to the first element in the array over the flexible interconnect. The printer elements monitor the interconnect to determine whether the command specifies a heater element under their control. The printer elements then actuate the specified heater element to cause an ink droplet to be ejected from a nozzle corresponding to the selected heater element.
