Brother HL-4200CN Service Manual page 9

LASER SAFETY (FOR 120 V MODEL ONLY)
This printer is certified as a Class I laser product under the U.S. Department of Health and
Human Services (DHHS) Radiation Performance Standard according to the Radiation
Control for Health and Safety Act of 1968. This means that the printer does not produce
hazardous laser radiation.
Since radiation emitted inside the printer is completely confined within protective housings
and external covers, the laser beam cannot escape from the machine during any phase of
user operation. However, the machine contains 5-milliwat, 700-800 nanometer
wavelength, GaAIAs laser diodes. Direct (or indirect reflected) eye contact with the laser
beam might cause serious eye damage. Safety precautions and interlock mechanisms
have been designed to prevent any possible laser beam exposure to the operator.
FDA REGULATIONS (FOR 120 V MODEL ONLY)
U.S. Food and Drug Administration (FDA) has implemented regulations for laser products
manufactured on and after August 2, 1976. Compliance is mandatory for products
marketed in the United States. The label shown on the back of the printer indicates
compliance with the FDA regulations and must be attached to laser products marketed in
the United States.
