Abstract
A printhead die includes end regions, a nozzle surface region, fluid passages, ejection chambers, fluid ejectors, non-ejection chambers, and heating resistors. The nozzle surface region is disposed between the end regions. The fluid passages include corresponding ejection nozzles. The ejection nozzles are disposed on the nozzle surface region. The fluid ejectors correspond to the ejection chambers. Each one of the fluid ejectors selectively ejects printing fluid through a corresponding ejection nozzle. The plurality of heating resistors corresponds to the non-ejection chambers. The heating resistors selectively provide heat to the end regions while not ejecting printing fluid through the ejection nozzles.
