SAFETY OF LASER BEAM (USA)
1. Safety of laser beam
This copier has been certified by the manufacturer to Class 1 level under the radiation
performance standards established by the U.S.DHHS (Department of Health and Human
Services) in 1968. This indicates that the product is safe to use during normal operation and
maintenance. The laser optical system, enclosed in a protective housing and sealed within the
external covers, never permits the laser beam to escape.
2. The CDRH Act
A laser-product-related act was implemented on Aug. 2, 1976, by the Center for Devices and
Radiological Health (CDRH) of the U.S. Food and Drug Administration (FDA). This act prohibits
the sale of laser products in the U.S. without certification, and applies to laser products
manufactured after Aug. 1, 1976. The label shown below indicates compliance with the CDRH
regulations and must be attached to laser products marketed in the United States. On this
copier, the label is on the left.
3. Optical unit
When checking the optical unit, avoid direct exposure to the laser beam, which is invisible.
Shown below is the label located on the cover of the optical unit.
4. Maintenance
For safety of the service personnel, follow the maintenance instructions in the other section of
this manual.
5. Safety switch
The power to the laser unit is cut off when the upper front cover is opened.
