CAUTION
This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This
means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of
procedures other than those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there
is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual
parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum
cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and
installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.
