Title: Harvey R. Markham: Innovator in Machine Operation and Electrostatic Copying
Introduction
Harvey R. Markham is a notable inventor based in Westminster, CO (US). He has made significant contributions to the field of machine operation and electrostatic copying, holding a total of 4 patents. His innovative approaches have enhanced the functionality and efficiency of various machines.
Latest Patents
One of his latest patents is titled "Optional machine inhibition for feature malfunction." This invention provides a method for continuing the operation of a machine despite the malfunction of a nonessential feature. If a feature program is determined to be nonoperable, a corresponding flag is checked to ascertain whether the feature is essential for the machine's continued operation. If it is not essential, the machine is allowed to continue functioning without the feature.
Another significant patent is "Charge density control for an electrostatic copier." This invention involves an electrophotographic copier equipped with a toner concentration control apparatus. It periodically conducts a toner-patch test cycle to measure the optical density of toner deposited on a photoconductor test area. The invention ensures that during critical events, such as a time period of non-use or a copier on/off operation, the photoconductor's charge magnitude is adjusted to maintain optimal performance.
