Abstract

A roofshooter thermal ink jet architecture 10 is depicted in Figure 1, with the nozzle plate 12 and nozzles 18 therein shown in dashed line. In this architecture, crosstalk between adjacent heaters 14 can be a problem. One way to solve the problem is to increase the length of the partitioning walls 16 to further isolate each heater. However, this increases the resistance to fluid refill after drop ejection, lowering the maximum operating frequency.
