Auto Sleep Function
If the machine is not operated for a period of about five minutes after copying has finished or after a
keying operation, the control panel power switch automatically moves to the OFF position, and the
machine enters the Sleep mode.
To turn the power back ON, press the power switch to the ON position.
MEMO
You can set the auto sleep time from 1 minute to 8 hours. (See "Auto Sleep Time," on p. 3-32 in the Reference
Manual .)
