Internal Laser Radiation; Ozone Safety - Epson EPL-N2500 Safety Instructions

Internal laser radiation

Max. Average Radiation Power:
Wavelength:
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.

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
5 mW at laser aperture
770 to 800 nm
