Laser safety labels

Warning:
w
The performance of procedures and adjustments other than those specified in the printer's
documentation may result in hazardous radiation exposure. Your printer is a Class 1 laser
product as defined in the IEC60825 specifications. The label shown is attached to the back of the
printer in countries where required.

Internal laser radiation

There is a Class III b Laser Diode Assembly that has an invisible laser beam inside the printer head unit.
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.
