The Maintenance Menu

The Maintenance menu can be accessed directly by pressing the # button.

Heat Off Timer 15 to 240 minutes You can turn off the heaters automatically when no errors are detected
and no print jobs are in progress. This option is used to choose the
interval before the heaters turn off automatically.
The printer will enter sleep mode when the Heat Off Timer expires. In
sleep mode, the control panel turns off and the internal motors and other
components consume less power. If an additional print drying system is
installed (included with the S50670, optional with other models), it will
turn off automatically.
To reactivate the control panel display, press any button in the control
panel except P. The control panel display will however turn off again if
no operations are performed for another 30 seconds under these
conditions. The printer and heaters are only fully reactivated when a
print job is received, the media loading lever is used, or another
operation involving printer hardware is performed.
