Ozone Safety Information
Ozone Emissions
Ozone gas is generated by laser printers as a by-product of the printing process.
Ozone is produced only when the CX11N 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 CX11N laser printer generates less than 0.1 ppm for eight (8) hours of continuous printing.
