vi Safety Instructions
Internal laser radiation
This is a Class III b Laser Diode Assembly that has an invisible laser beam.
The printer head unit is NOT A SERVICE ITEM, therefore, the printer head
unit should not be opened under any circumstances. An additional laser
warning label is affixed to the inside of the printer.
CDRH regulations
For information about the Center for Devices and Radiological Health
of the U.S. Food and Drug Administration, see the Reference Guide.
Ozone safety
Ozone emission
Ozone gas is generated by laser printers as a by-product of the printing
process. Ozone is produced only when the printer is printing.
Ozone exposure limit
The recommended exposure limit for ozone is 0.1 parts per million (ppm)
expressed as an average time-weighted concentration over an eight
(8) hour period.
The EPSON laser printer generates less than 0.1 ppm for eight (8) hours of
continuous printing.
Minimize the risk
To minimize the risk of exposure to ozone, you should avoid the following
conditions:
❏ Use of multiple laser printers in a confined area
❏ Operation in conditions of extremely low humidity
❏ Poor room ventilation
❏ Long, continuous printing together with any of the above
Printer location
The printer should be located so that the exhaust gases and heat
generated are:
❏ Not blown directly into the user’s face
❏ Vented directly out of the building whenever possible
Max. Average Radiation Power: 5 mW at laser aperture
Wavelength: 785 nm
