Laser Components
Warning: This printer generates a laser beam as part of the printing
process. The laser beam is a concentrated narrow beam of
infrared light. The laser beam in this machine is invisible.
Although you cannot see the beam, it can still cause severe
eye damage. Direct eye exposure to the laser beam may
cause eye injury or blindness.
To avoid permanent eye damage, follow these directions:
■
Before starting any service procedure, switch off the printer power and unplug
the power cord from the AC wall outlet.
■
Do not disassemble the Raster Output Scanner Assembly (laser scanner) or any
laser component that displays a Laser Warning Sticker.
■
Use caution when you are working around the Raster Output Scanner Assembly
or when you are performing laser related troubleshooting or repair procedures.
■
Never place a mirror or a reflective tool or object in the laser beam path.
■
Do not disassemble the printer in such a way that the laser beam can exit the
print engine during a print cycle.
