Introduction

Internal laser radiation
This is a Class IIIb Laser Diode Assembly that has an invisible
laser beam. The printer head unit is NOT A FIELD SERVICE
ITEM. Therefore, the printer head unit should not be opened
under any circumstances.
Ozone safety
Ozone gas is generated by laser printers as a by-product of the
printing process; it is produced only during printing. The
recommended exposure limit for ozone is 0.1 parts per million
(ppm) expressed as an average time-weighted concentration
over an eight hour period.
The EPL-N2000 laser printer generates <0.01 ppm for 8 hours of
continuous printing, assuming a closed room of approximately
1000 cu ft (8’
×
10’
×
12’).
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.
The printer should be located so that the exhaust gases and heat
generated are not blown directly into the user's face and are
vented directly out of the building whenever possible.
