Abstract: There is disclosed a color xerographic printing system which utilizes a full length developer to develop a first latent image and registration marks on the margins along the first latent image. The color printing system of this invention, also utilizes two margin chargers prior to a second developer. Each one of the margin chargers restores the charge under the developed registration marks to prevent the registration marks from attracting more toner.

Abstract: A laser diode is disclosed which utilizes a feedback system which substantially reduces the dependency of the optical output power of the laser diode on laser junction temperature which is dependent on the pixel pattern. The feedback system of this invention generates a feedback signal through comparison of an averaged train of pixel information against an averaged optical output power from the back photodiode of the laser diode. By comparing the two averaged signals, one can determine the fluctuations of the heat in the laser diode. At any given point, any discrepancy between the two averaged signals shows a temperature change in the laser diode. Depending on the amount of the difference between the two signals, the degree of excess temperature can be determined and the difference will be used for feedback correction.

Abstract: A thin film organic light emitting diode with edge emitter waveguide comprises, in sequence, a substrate, a waveguide, an anode, a hole transport layer, an electroluminescent layer, and a cathode. Voltage applied between the anode and cathode causes the electroluminescent layer to emit light through the hole transport layer and the anode into the waveguide where the light is internally reflected within the waveguide and propagates through the length of the waveguide to be emitted through the edge of the waveguide. The non-emission edge of the waveguide may be sloped with a conductor layer to the anode and a conductor layer to the cathode forming a reflective surface to the non-emission edge.

Abstract: A raster output scanning system is disclosed which utilizes a single light source, an electro-optical device and a beam-splitter to generate two partially overlapping light beams in order to scan one scan line in which the width of the scan line can be adjusted electronically. The two partially overlapping light beams in effect generate a resulting light beam. By changing the polarization factor of the electro-optical device, the intensities of the two light beams can be modified which in turn will change the width of the resulting light beam and as a result the spot size changes. By changing the spot size, the width of the scan line can be adjusted. Also, by changing the polarization factor, the position of the resulting light beam can be changed.

Abstract: A raster output scanning system is disclosed which utilizes two light beams to double scan two scan lines on a photoreceptor in order to generate three exposure levels required for a tri-level printing system. In the raster output scanner of this invention, the two light beams scan two separate scan lines. At the completion of the simultaneous scanning of two light beams when the first light beam starts to scan a new scan line, the second light beam start to scan the scan line that the first light beam just completed scanning. In this invention the first light beam generates two exposure levels and the second light beam adds additional exposure to the second exposure level in order to generate a third exposure level. The same method can be utilized to generate additional levels for printing systems with more xerographic levels than three.

Abstract: In a raster output scanner, a system for using one original beam and one facet of a rotating polygon to generate two consecutive scan lines. The original beam is first separated into two beams in a beam splitter. The resultant beams are polarized ninety degrees apart, and directed to the modulator. The beams are a sufficient distance apart so that the A/O modulator can modulate each beam with a minimum of crosstalk. The output beams are then brought together to within one scan line separation by a beam recombiner, which is a reversed beam splitter. The beams can be brought together to this close proximity without optical interference because the beams are plarized ninety degrees apart.

Abstract: A variable attenuator for controlling scanning beam intensity having a twisted nematic liquid crystal for rotating the beam, a polarization analyzer for detecting the degree of alteration in the polarization of the beam by the crystal comprising a polarizing beam splitting plate separating the beam into primary and secondary beams, a photocell providing a signal reflecting the intensity of the secondary beam, a control for adjusting power to the crystal in response to the signal, a glass plate at an angle of incidence equal to but opposite from that of the beam splitting plate for correcting aberrations to the primary beam, and an anti-reflective coating on the optical surfaces of the crystal.In a second embodiment, the plates are replaced by a polarizing cube. In a third embodiment, to obviate fluctuations in the attenuator output, the glass plate instead serves as the source of the beam component to the photocell.
