This is a Class IIlb Laser Diode Assay that has an invisible laser
beam. The print head unit is NOT A FIELD SERVICE ITEM.
Therefore, the print head unit should not be opened under any
circumstance.
Ozone Emission
During printer operation, a small amount of ozone is released.
This amount is not large enough to affect human beings
adversely.
However, it is best to make sure the room where you are using
the printer has adequate circulation, especially when you are
printing a high volume of materials or using the printer
continuously over a long period of time.
