The contents are subject to change without notice. CAUTION This product is a class 1 laser product that complies with 21CFR 1040 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.
