  • Patent number: 8045879
    Abstract: Disclosed are a method of controlling moisture in an electrophotographic apparatus having a fuser assembly, and corresponding electrophotographic apparatus. The method includes measuring a cavity temperature of an inner portion of the electophotographic apparatus, measuring a cavity relative humidity of an inner portion of the electophotographic apparatus, calculating a cavity dewpoint temperature using the measured cavity temperature and the measured cavity relative humidity, determining a difference between the cavity temperature and the cavity dewpoint temperature, and if the difference between the cavity temperature and the cavity dewpoint temperature drops below a predetermined threshold, turning on a heater device in the fuser assembly to control moisture in the electrophotographic apparatus.

  • Patent number: 6002507
    Abstract: A solid state laser beam scanning system having a single crystal silicon deflection and scanning mirror integrated with a laser diode. By combining the techniques of deep reactive ion etching of silicon with solder bump bonding techniques, completed and tested laser diodes are integrated with silicon substrates supporting micro-electro-mechanical systems layers.
