摘要： A pre-scan optics assembly for a laser scanning device. A housing includes reference surfaces against which a pre-scan lens is directly referenced, to restrain the lens against rotation about the optical axis and the scan axis of the device. A lens carrier is attached to the housing and has an abutment surface to restrain the lens against rotation about the process axis of the device. A spring clip secures position of all components in the desired locations. The optical system aperture is formed directly in a wall of the lens carrier.

摘要： An imaging apparatus includes a machine frame unit having a plurality of mounting locations and a pivot location, a printhead base having a first end and a second end, and a first resilient elongate member having a first proximal end and a first distal end. A mounting tab is coupled to the first distal end of the first resilient elongate member, and is coupled to a first mounting location of the plurality of mounting locations of the machine frame unit. A pivot post, having an axis of rotation, pivotally couples a mounting plate to the pivot location of the machine frame unit. An adjustment device is coupled to the machine frame unit, the adjustment device having an engagement member for engaging at least one of the printhead base and the first resilient elongate member to effect a deflection of the first resilient elongate member and a corresponding movement of the printhead base. At least the first resilient elongate member is configured to define a virtual pivot axis for the movement of the printhead base when the mounting tab and the mounting plate are fixedly attached to the machine frame unit. A location of the virtual pivot axis substantially corresponds to a location of the axis of rotation of the pivot post.

摘要： A method of reversing a laser beam in a machine includes orienting a pair of reflective surfaces at an angle of approximately 90° relative to each other. The laser beam is directed in a first direction such that the laser beam sequentially impinges upon a first of the reflective surfaces reflects off of the first reflective surface, impinges upon a second of the reflective surfaces, and reflects off of the second reflective surface in a second direction substantially parallel to and opposite the first direction. A pivot axis is substantially parallel to each of the reflective surfaces. Each of the reflective surfaces is pivoted about the pivot axis by a substantially equal angle to thereby change a position of the laser beam after reflecting off of the second reflective surface.

摘要： An electrophotographic machine mirror assembly includes a mirror having two opposite ends and a reflective surface. A laser device scans a laser beam along the reflective surface to define a fold line thereon. The fold line extends substantially between the two opposite ends of the mirror. At least one fixed mounting device has a support surface. At least one rotational device is attached to the mirror. The at least one rotational device has an arcuate surface defining an imaginary circle and engaging the support surface of the at least one fixed mounting device. The imaginary circle has a center substantially coincident with the fold line of the reflective surface. The at least one rotational device rotates about the center of the imaginary circle to thereby rotate the mirror about the fold line.

摘要： An electrophotographic imaging apparatus includes a plurality of photoconductive drums and a plurality of printhead assemblies. Each drum has an axis of rotation and a photoconductive peripheral surface. A plurality of the axes of rotation of the drums lie in a generally common plane. The peripheral surface of each drum rotates in a common direction defining an advance direction of the print medium. Adjacent drums are disposed at a first distance away from each other between the axes of rotation. Each printhead assembly is associated with a respective drum and is configured for generating a laser beam which impinges upon the respective drum along a line of incidence. The printhead assemblies are disposed at a second distance from one to another which is greater than the first distance.
