Abstract
A fluid ejection device having a first fluid feed source having a first fluid feed source edge in communication with a substrate surface, first firing resistors disposed along the first fluid feed source and configured to respond to a first current to heat fluid provided by the first fluid feed source, and a reference conductor. The reference conductor is configured to conduct the first current from the first firing resistors, wherein the reference conductor is disposed between the first fluid feed source edge and the first firing resistors.
