Inkjet printer having a printhead with a bi-layer thermal actuator coil
First Claim
1. A printhead for an inkjet printer, the printhead having a plurality of micro-electromechanical ejection mechanisms arranged in a wafer substrate, each mechanism comprising:
- chamber walls and a roof formed on said substrate to define an ink chamber, one wall defining a slot therein, and an ink supply channel defined through the substrate to said chamber; and
a bi-layer thermal actuator coil fast with the substrate and ending in a strut extending through the slot, said strut fast with a paddle device within the chamber.

Abstract
Provided is a printhead for an inkjet printer. The printhead has a plurality of micro-electromechanical ejection mechanisms arranged in a wafer substrate, with each mechanism having chamber walls and a roof formed on top of said substrate to define an ink chamber. One wall of the chamber defines a slot therein. The mechanism also includes an ink supply channel defined through the substrate to said chamber. The mechanism includes a bi-layer thermal actuator coil fast with the substrate and ending in a strut extending through the slot, said strut fast with a paddle device within the chamber.
