Title: Donato D Evangelista: Innovator in Copy Technology

Introduction

Donato D Evangelista is a notable inventor based in Webster, NY (US). He has made significant contributions to the field of copy technology, holding a total of 6 patents. His innovative designs have improved the efficiency and functionality of high-speed copy machines.

Latest Patents

One of his latest patents is a paper cooling system. This invention provides a method and apparatus for cooling copy sheets in a high-speed copy machine while en route to an output tray. The system utilizes a blower connected to manifolds positioned on opposite sides of the copy sheets. Airflow is supplied to both sides of the sheets as they are conveyed throughout the paper path, effectively cooling them before they enter the output tray and preventing the fusing of the sheets together. Another significant patent involves registering images on both sides of a substrate. This process includes a motor-driven document transport that advances a substrate to a transfer station for image transfer. The substrate is then inverted, allowing for the registration of a second image. A sensor detects the leading and trailing edges of the substrate, while an encoder produces pulses to help determine the substrate's width. This technology ensures precise alignment of images on the substrate.
