ƒ  Be sure to turn off the main switch  and disconnect the power plug from the power 
outlet before beginning any disassembly or  adjustment of the laser unit. This 
copier uses a class IIIb laser beam with  a wavelength of 655 nm and an output of 7 
mW. The laser can cause serious eye injury. 
3.6.2  LASER OPTICS HOUSING UNIT 
 
ƒ  Before installing a new laser optics housing unit, remove the sponge padding and 
the tag from the new unit. 
 
ƒ  A new laser optics housing unit has a bra cket to protect the LD units. When you 
install the new unit, do not remove the bracket until near the end of the installation
