Safety Information
Laser Safety
The Center for Devices and Radiological Health (CDRH) of the U.S. Food
and Drug Administration has implemented regulations for laser products
manufactured since August 1, 1976. Compliance is mandatory for products
marketed in the United States. This printer is certified as a “Class 1” 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. Since radiation emitted inside this printer is
completely confined within protective housings and external covers, the
laser beam cannot escape during any phase of normal user operation.
WARNING
Never operate or service the printer with the protective cover
removed from the Laser/Scanner Assembly. The reflected beam,
although invisible, can damage your eyes.
Ozone Emission
The HP LaserJet 4V and HP LaserJet 4MV printers do not use high voltage
corona wires in the electrophotographic process, and therefore generate no
measurable ozone gas (O
3
). These printers instead use charging rollers in
the toner cartridge and in the print engine.
