W A R N I N G
This printer uses a laser as part of the printing process.
The laser beam is a very powerful, straight, narrow
beam of light that produces extreme heat at its focal
point. The laser beam in this printer is invisible.
Although you cannot see the beam, it can still cause
severe damage. Direct eye exposure to the laser beam
may cause eye injury or blindness.
Never place a mirror or a reflective tool or object in the
laser beam path.
