Introduction

Roger E Baldwin is a notable inventor based in Hilton, NY (US). He has made significant contributions to the field of laser printing technology, holding a total of 4 patents. His work has been instrumental in enhancing the efficiency and accuracy of laser printers.

Latest Patents

Among his latest patents is a beam position sensor for a light beam scanner. This innovative device is designed for use in laser printers, which utilize three diode lasers emitting at different wavelengths. The beams from these lasers are combined using dichroic plates to create a single beam. This combined beam is then scanned onto a receiving medium by a polygon. The beam position sensor is crucial as it senses the polygon's position, providing a synchronizing signal to ensure that each raster line in the printer starts at the correct position. The sensor includes a diode laser and optics that project a beam onto the polygon, with the reflected beam returning to a photodetector to initiate a new raster line at the appropriate time.
