CAUTION

This laser printer is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of theCDRH standard and IEC825. This means that this machine does not produce hazardous laserradiation. The use of controls, adjustments or performance of procedures other than those specifiedherein 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 isachieved on the eyes 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 timeof servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchangedas 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 upper frame and the middle frame contains the safety interlock switch.

Do not defeat the safety interlock by inserting wedges or other items into the switch slot.
