Title: Innovations of Clark W Crawford

Introduction

Clark W Crawford is a notable inventor based in Wilsonville, Oregon, with a remarkable portfolio of 18 patents. His contributions to the field of printing technology have significantly advanced the efficiency and reliability of printers.

Latest Patents

Among his latest innovations is the "Apparatus and method for deskewing media in a printer." This invention provides a method and apparatus for deskewing a sheet of media traveling through a paper path in a printer. It involves forming a buckle in the sheet of media by over-driving it into stationary deskew rollers that create a deskew nip downstream. The deskewing bias element, which consists of articulated segmented surfaces, contacts the buckle and aligns the leading edge of the sheet with the deskew nip, effectively removing any skew. Another significant patent is the "Ink feed system," which offers an improved ink stick supply assembly for solid ink color printers. This system reliably feeds solid ink sticks from a loading bin to melt plates, guiding the molten ink into individual color reservoirs in the printer print head. It also includes low ink and empty ink level sensors to notify the operator when to replenish the ink supply.
