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.
2) Do not look into the machine with the Main Switch turned on after removing the Toner/Developer Unit 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 Unit.
4) The cover of Laser Printer Unit contains the Safety Interlock Switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

with a new one.
In addition to the replacement of F101 and F100, the factor causing
F101 and F100 to open must also be repaired. If not, F101 and
