A cover is adapted to form part of a housing of a laser scanning unit. The cover comprises a main body having walls for defining at least one opening adjacent a lens located in a base of a laser scanning unit housing. At least one of the walls comprising seal structure formed integral with an adjacent portion of the one wall. The seal structure is adapted to engage a side portion of the lens so as to seal a gap between the lens side portion and the one wall.

A collimation assembly is associated with a printhead housing for generating a substantially collimated laser beam. The collimation assembly comprises: a collimation housing mounted to the printhead housing to support a collimation lens; an adjustment bracket positioned adjacent the collimation housing; and a light source generating a light beam. The adjustment bracket comprises a mount member for receiving the light source such that the light beam is directed toward the collimation lens. The mount member may include first and second sections and a hinge defined between the first and second sections so as to allow the mount member to flex when receiving the light source.

A lens has a lens body (), reinforcing extensions () and a clear aperture () surrounded on top and bottom by lens body. The lens is suitable for spot scanning. The lens is made of a water absorbing material, such as most polymers, particularly acrylate polymers. Aluminum sheets as vapor barriers are attached on each side of the lens body. This results in excellent resistance to change or distortion in high humidity environments.
