- Wear a wristband or the like as far as possible to remove static electricity of the human body.
- Keep the front cover closed. Buzzer goes off when the machine is left powered on with the front
cover open for five minutes or longer to prevent the drum deterioration due to exposure to light.
- When opening the front door in a removal/replacement operation, cover the drum to keep it
from being exposed to light.
- Remove PAPER TRAY, PHD unit, TONER CARTRIDGE, and FUSER, and put them in a place
where they do not affect the procedure. (Note that the service procedures can be performed with
those parts in place depending on the target section of removal/replacement.)
