If the case is half full or more, empty it in an appropriate bag for collection. Or, replace the waste toner collection

- Do not dispose of waste toner in fire. (Doing so can cause an explosion.)

8) Check the operation of the leakage breaker.

the breaker operates normally (i.e., the lever will shift to OFF to cut off the power).
If the leakage breaker fails to operate normally, replace the breaker, and make a check once again.
<Resetting>
When you have checked the operation of the leakage breaker, turn off the power switch, shift the lever to ON, and
turn on the power switch.
