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.
Maximum Radiation Power: 5.0 × 10
-4
W
Wave Length: 780 ± 20 nm
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-N1200 laser printer generates <0.01ppm 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.
