Title: Innovations of Lawrence A Hand

Introduction

Lawrence A Hand is a notable inventor based in Palo Alto, CA. He has made significant contributions to the field of thermal inkjet technology. With a total of 2 patents, his work has had a lasting impact on printing technology.

Latest Patents

One of his latest patents is the ink-cooled thermal ink jet printhead. This innovative printhead features an efficient heat exchanger located on the back side, which eliminates the need for heat sinks. All ink flowing to the firing chamber passes through this heat exchanger. The design ensures that almost all residual heat absorbed by the printhead substrate is transferred to the ink as it flows to the firing chamber. Additionally, the pressure drop of the ink flowing through the heat exchanger is low enough to maintain a high refill rate of the firing chambers. The heat exchanger can have one or more active sides and has minimal thermal mass, significantly reducing the overall thermal mass of the printhead. This advancement reduces the warm-up time of the printhead to a fraction of a second.
