Mounting assembly for a mirror in a laser scanning unit of an image forming device

A mounting assembly for mounting a mirror to a frame in a laser scanning unit of an electrophotographic image forming device, comprising:

• a bracket attached between the frame and the mirror, the bracket having a first surface with a first set of protrusions extending from the first surface and contacting against the frame to define a first gap between the frame and the first surface of the bracket, and a second surface with a second set of protrusions extending from the second surface and contacting against the mirror to define a second gap between the mirror and the second surface of the bracket;
• a first adhesive in the first gap that fixedly attaches the bracket to the frame;
• and
• a second adhesive in the second gap that fixedly attaches the bracket to the mirror.

A laser scanning unit for an electrophotographic image forming device, comprising:

• a frame;
• a scanning member positioned within the frame and having at least one reflective surface for reflecting light incident thereon;
• a light source for emitting a light beam to be incident on the at least one reflective surface of the scanning member during a scanning operation;
• a mirror for deflecting the light beam from the scanning member to a photosensitive surface;
• and
• at each opposite side of the frame, a bracket adhesively attached between the mirror and the frame to mount the mirror to the frame, the bracket having a first surface with a first set of protrusions extending from the first surface and contacting against the frame to define a first gap between the frame and the first surface of the bracket that limits adhesive thickness therebetween, and a second surface with a second set of protrusions extending from the second surface and contacting against the mirror to define a second gap between the mirror and the second surface of the bracket that limits adhesive thickness therebetween.
