ADDRESS ARCHITECTURE FOR FLUID EJECTION CHIP

摘要

A printhead including one or more fluid vias in fluid communication with a fluid supply, each of the one or more fluid vias being associated with a first number of heating elements, the heating elements being divided into groups of a second number of heating elements so as to form a number of primitive groups, and an electrical interface having at least one shift register that receives primitive address data to allow for selective application of electrical signals to the heating elements so that fluid is ejected from the printhead in accordance with image data, the number of primitive groups being dependent on the print resolution of the printhead so that a number of bits required for the at least one shift register to address each heater is independent of the print resolution of the printhead.

主权项

1. A method of inkjet printing, comprising:
transmitting primitive address data to at least one shift register of a printhead, the at least one shift register having a number of bits dependent upon a number of primitive groups of heating elements of the printhead, each primitive group comprising a first number of heating elements of a total, second number of heating elements of the printhead, the number of bits independent of a print resolution of the printhead such that the printhead is configured for control by an electrical interface that is common for a plurality of different print resolutions of the printhead; and selectively applying, by the at least one shift register, one or more electrical signals to the heating elements to eject ink supplied by one or more fluid vias in fluid communication with the heating elements.
