Latest Patents

Selby holds a patent for "Compensation for Fine Line Prints." This invention provides a method for compensating environmental effects such as temperature, humidity, and photoconductor aging, which can adversely impact print quality. By analyzing print data, Selby identifies critical compensation locations, particularly in single pel lines. The invention employs a series of clock pulses with varying phase displacements, selected based on environmental variations, to modify print data at these identified locations. This method effectively controls the width of lines perpendicular to the scan direction by adjusting the leading and trailing edges of pulses, thereby influencing the duration of print pulses. For lines parallel to the scan direction, width control is achieved by adding gray pulses, with both edges controlled according to environmental variations.
