 Turn off the machine and unplug its power cord before performing any procedure
in this section. Laser beams can seriously damage the eyes.
 This laser unit uses four laser beams produced by a Class IIIb LDA with a
wavelength of 660 nm and intensity of 15 mW. Direct exposure to the eyes could
cause permanent blindness.
 Before performing any replacement or adjustment of the laser unit, push the
machine power switch to switch the machine off. Then unplug the machine from
the power source.
 Do not touch the machine for 10 minutes. This allows enough time for the fusing
unit to cool and for the polygon motor to stop rotating.
 Never power on the machine with any of these components removed: 1) LD unit,
2) polygon motor cover, 3) synchronization detector.
