Replacement of Polygonal Mirror Assembly
CAUTIONS
• Use care not to let the polygonal mirror assembly fall or bump. If the polygonal mirror assem-
bly is shocked, its axis of rotation may be misaligned and thus it may become useless.
• Never touch the mirror face of the polygonal mirror (even when you are wearing gloves). If the
mirror face of the polygonal mirror is touched, the polygonal mirror will become unusable.
