Abstract
In one embodiment, the present invention recites a fluid ejection device comprising a first drop ejector associated with a firing chamber. The first drop ejector is configured to cause fluid having a first drop weight to be ejected from the firing chamber, wherein the first drop ejector includes a first heating element and first drive circuitry electrically coupled with the first heating element. The present embodiment further comprises a first bore disposed within an orifice layer disposed proximate the first drop ejector and associated with the first drop ejector. The present embodiment also comprises a second drop ejector associated with the firing chamber. The second drop ejector is configured to cause fluid having a second drop weight to be ejected from the firing chamber, wherein the second drop ejector includes a second heating element and second drive circuitry electrically coupled with the second heating element. The present embodiment further comprises a second bore disposed within the orifice layer disposed proximate the second drop ejector, and the second bore is associated with the second drop ejector.
