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 EPL-5700 laser printer generates <0.01ppm for 8 hours of
continuous printing when considering a close d room of
approximately 1000 cu ft (8’ × 10’ × 12’).
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 (see above)
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
