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
Product location
The product 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
Wavelength: 770 to 795 nm
