Press if the machine will not be used for a long period of time, such as overnight Put the machine into Sleep mode as a safety precaution.


When in sleep mode When the machine enters sleep mode, lights up yellow green. Situations in which the machine does not enter sleep mode The machine will not enter sleep mode in the following situations: When the machine is in operation When the Data indicator is lit up or blinking When the machine is performing an operation such as adjustment or cleaning When a paper jam occurs When the receiver of the external telephone is off the hook When the machine is set such that the fax incoming ring will not sound When the menu screen is displayed When a job is waiting to be scanned to a USB memory device or to a computer When an error message is displayed on the screen (There are some exceptions. The machine sometimes enters sleep mode when an error message is displayed.) When the machine is communicating with an LDAP server, etc. When the SSID/network key screen for Direct Connection is displayed When settings are being imported or exported If the situation preventing the machine from entering sleep mode continues, the machine performs automatic adjustment (automatic calibration) to maintain print quality. Calibration uses toner and may therefore result in a decrease in the lifetime of the toner cartridges.

Changing the Auto Sleep Time Value

Auto Sleep Time is a function that automatically puts the machine into the sleep mode if it remains idle for a specified length of time. We recommend using the factory default settings (<Timer/Energy Settings>) to reduce power usage. If you want to change the amount of time that elapses before the machine enters the auto sleep mode, perform the procedure below.

<Menu>

Set the amount of time that elapses before the machine automatically enters sleep mode

<Apply>

Changing the Sleep Mode Setting to the Specified Time

You can configure a setting so that the machine is placed into the sleep mode at the specified time. You can also configure a setting so that the sleep mode is released at the specified time.
