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 × 10-4W

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.
