1. SAFETY INFORMATION
Laser Safety
Internal Laser Radiation
Maximum Average Radiation Power: 19.5 µW (Di251)/27.8 µW (Di351) at laser aperture of
the print head unit
Wavelength: 770-795 nm (Di251)
775-795 nm (Di351)
This product employs a Class 3b Laser Diode that emits an invisible laser beam.
The Laser Diode and 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.
CDRH regulation
This copier is certified as a Class ILaser product under the Radiation Performance Stan-
dard according to the Food, Drug and Cosmetic Act of 1990. Compliance is mandatory for
Laser products marketed inthe 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. Depart-
ment of Health and Human Services (DHHS). This means that the device does not produce
hazardous laser radiation.
CAUTION: The use of controls, adjustments or performance of procedures
other than those specified in this manual may result in hazardous radiation
exposure. Because of this, Minolta strongly recommends that you operate
your copy machine only as described in this documentation.
