Abstract
In a raster output scanning system (ROS) of a xerographic printing device, a plurality of input optical channels direct at least one of a plurality of light beams onto separate facets of a deflector, which may be a rotating polygon mirror. The deflector deflects the light beams onto disparate optical paths. An optical system located on the disparate optical paths directs at least one of the light beams onto each of first, second, third and fourth image receiving locations. The image receiving locations may comprise a plurality of photoreceptors.
Claims26
A raster output scanning system for a printing device, comprising:
- a polygon having a plurality of facets;
- a plurality of input optical channels, a first one of the input optical channels directing a first one of a plurality of light beams onto a first facet of the polygon, and a second one of the input optical channels directing a second one of the plurality of light beams onto a second facet of the polygon, the polygon deflecting one of the light beams onto each of a plurality of disparate optical paths;
- and
- an optical system located on the disparate optical paths, the optical system directing at least one of the light beams onto each of first, second, third and fourth image receiving locations.
A raster output scanning system for a four station printing device, comprising:
- a plurality of light sources each emitting at least one of a plurality of light beams;
- a polygon mirror having a plurality of facets;
- a plurality of input optical channels, a first one of the input optical channels directing a first one of the plurality of light beams onto a first facet of the polygon, and a second one of the input optical channels directing a second one of the plurality of light beams onto a second facet of the polygon, the facets of the polygon directing the light beams onto disparate optical paths;
- and
- optical means for directing at least one of the light beams onto each of first, second, third and fourth image receiving locations.
A method of scanning with a raster output scanning system having a plurality of light beams and a rotating polygon mirror, comprising:
- directing a first one of the plurality of light beams through a first one of a plurality of input optical channels to a first facet of the rotating polygon mirror;
- directing a second one of the plurality of light beams through a second one of the plurality of input optical channels to a second facet of the rotating polygon mirror;
- simultaneously deflecting at least one of the light beams onto each of first, second, third and fourth image receiving locations.
