The contents are subject to change without notice.

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.
CAUTION
Warning!
This product is a class A product.
If it is operated in households, offices or similar surroundings, it can produce radio interferences at other
appliances, so that the user has to take adequate countermeasures.
