Fluid ejection device

摘要

A fluid ejection device includes a plurality of address lines and a fire line for communicating a fire signal. The device also includes a plurality of nozzle circuits coupled to the fire line and the plurality of address lines. Each nozzle circuit is configured, when enabled, to eject fluid via a different one of a plurality of nozzles in response to the fire signal. A subset of the plurality of address lines is coupled to each pair of the plurality of nozzle circuits. Each subset that is coupled to one of the pairs of nozzle circuits is selected so that simultaneous activation of every address line of that subset simultaneously enables each nozzle circuit in the pair or pairs of nozzle circuits coupled to that triad and none of the other nozzle circuits of the plurality of nozzle circuits.

1. A printer cartridge, comprising:
a plurality of address lines, including a first subset of address lines and a second subset of address lines, the first and second subsets combined including four address lines; a fire line for communicating a fire signal; and a plurality of nozzle circuits, including a first pair of nozzle circuits and a second pair of nozzle circuits, coupled to the fire line and the plurality of address lines, each nozzle circuit configured, when enabled, to eject fluid via a different one of a plurality of nozzles in response to the fire signal, wherein a subset of the plurality of address lines is coupled to each pair of the plurality of nozzle circuits so that, for each given subset of address lines coupled to one or more of the pairs of the plurality of nozzle circuits simultaneous activation of every address line of that subset simultaneously enables each nozzle circuit in the pair or pairs of nozzle circuits coupled to a given triad and none of the other nozzle circuits of the plurality of nozzle circuits, wherein a first address line of the four address lines is coupled to each nozzle circuit of the first nozzle circuit pair; wherein a second address line of the four address lines is coupled to a first but not a second nozzle circuit of the first nozzle circuit pair and to a first but not a second nozzle circuit of the second nozzle circuit pair; wherein a third address line of the four address lines is coupled to the second but not the first nozzle circuit of the first nozzle circuit pair and to the second but not the first nozzle circuit of the second nozzle circuit pair; and wherein a fourth address line of the four address lines is coupled to each nozzle circuit of the second nozzle circuit pair.
