Title: John F. Moreland: Innovator in Printer Technology

Introduction

John F. Moreland is a notable inventor based in Fairport, NY (US), recognized for his contributions to printer technology. With a total of 3 patents, he has made significant advancements in optimizing printing processes.

Latest Patents

One of his latest patents is a method and apparatus for optimizing substrate speed in a printer device. This invention involves a printer control apparatus and an algorithm designed to determine the peak instantaneous speed of a substrate through a thermal inkjet printer. The printer includes a dryer module, a print head module, and a controller. The method determines the tolerable peak instantaneous speeds of the substrate through the print head and dryer modules, which operate out of phase from one another. The lower of the two speeds is selected as the optimum instantaneous speed of the substrate through the printer, with the controller executing the methods disclosed.

Another significant patent is the development of a multiple mode raster scanner. This invention features an image input terminal (IIT) with an automatic document handler for feeding documents into a registered position on the IIT platen. The IIT includes multi-element scanning arrays with cooperating scan lamps and optics on a movable carriage. The analog image signals generated by the scanning arrays are processed in separate channels and combined into a serial stream. This stream may be thresholded or screened to provide binary level image signals or converted to multi-bit grayscale. A control system with a microprocessor synchronizes the operation of the scanning carriage, document handler, and image signal processing.
