Introduction Chapter 1
Internal laser radiation
Maximum Average Radiation Power: 17.3 μW (bizhub 423/363)/13.9 μW (bizhub 283/223) at the laser
aperture of the print head unit.
Wavelength: 770-800 nm
This product employs a Class 3B laser diode that emits an invisible laser beam.
The laser diode and the scanning polygon mirror are incorporated in the print head unit.
The print head unit is NOT A FIELD SERVICE ITEM:
Therefore, the print head unit should not be opened under any circumstances.
The laser opening can be found in the device with the drum unit removed.
CDRH regulations
This machine is certified as a Class 1 Laser product under Radiation Performance Standard according to the
Food, Drug and Cosmetic Act of 1990. Compliance is mandatory for Laser products marketed in the United
States and is reported to the Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration of the U.S. Department of Health and Human Services (DHHS). This means that the device
does not produce hazardous laser radiation.
The label shown on page 1-20 indicates compliance with the CDRH regulations and must be attached to
laser products marketed in the United States.
This is a semiconductor laser. The maximum power of the laser diode is 7 mW and the wavelength is 770-
800 nm.
For European users
This is a semiconductor laser. The maximum power of the laser diode is 7 mW and the wavelength is 770-
800 nm.
