Patent ID: 7036914

Claim:
A fluid ejection device, comprising: a plurality of fixing cells, each firing cell including: at least one firing input adopted to receive a corresponding timed energy signal having timed energy pulses; an enable input set including at least one enable input adapted to receive enabling signaling and including a first enable input, wherein the firing cell is adapted to be enabled for activation based on the enabling signaling and wherein the enabled firing cell is adapted to be activated by a timed energy pulse to eject fluid; and wherein the plurality of firing cells are grouped into fire groups of firing cells including a first fire group and a second fire group, wherein the at least one firing input or each firing cell of the first fire group is electrically coupled to the at least one firing input of every firing cell of the first fire group and is electrically isolated from the at least one firing input of every firing cell of the second fire group; wherein the plurality of firing cells are also grouped into data groups of firing cells including a first data group having a first firing cell in the first fire group and a second firing cell in the second fire group, wherein the first enable input of each firing cell of the first data group is electrically coupled to the first enable input of every firing cell of the first data group.
