Abstract
An optical scanner includes a rotatable polygon mirror and a second mirror. The rotatable polygon mirrors includes a block having a first wall, a second wall, and reflective surfaces extending between the first and second walls, the reflective surfaces being angularly offset from one another along a periphery of the block; a polygon mirror axle extending into the block through at least one of the first and second walls, about which the block rotates; a motor driving rotation of the block; and chamfers in the block, each of the chamfers being bounded by a pair of adjacent reflective surfaces and the second wall. The second mirror is pivotable along an axis orthogonal to the polygon mirror axle and more proximate to the second wall of the block than the first wall of the block.
