First Claim
Patent Images
1. A printhead integrated circuit comprising:
- a wafer substrate defining a nozzle outlet port;
an electromagnetic piston mounted to the wafer substrate via torsion springs, said piston operatively forced towards the outlet port when activated; and
a solenoid coil positioned on the wafer substrate about the piston to activate the piston when a current is passed through the coil.

Abstract
The invention provides for a printhead integrated circuit for an inkjet printer. The printhead integrated circuit includes a wafer substrate defining a nozzle outlet port. The printhead integrated circuit also includes an electromagnetic piston inside the chamber, the piston mounted to the wafer substrate via torsion springs, said piston operatively forced towards the outlet port when activated. Also included is a solenoid coil positioned on the wafer substrate about the piston to activate the piston when a current is passed through the coil.
