2.11.3 AUTO OFF MODE
There are two Auto Off modes: Off Stand-by mode and Off mode. The difference
between Off Stand-by mode and Off mode is the machine’s condition when it
enters Auto Off mode.
Entering off stand-by and off modes
The machine enters the Off Stand-by mode or Off mode when one of the following
is done.
• The auto off timer runs out
• The operation switch is pressed to turn the power off
If one or more of the following conditions exists, the machine enters Off Stand-by
mode. If none of these conditions exist, the machine enters Off Mode.
• Error or SC condition
• An optional G4 unit is installed
• Image data is stored in the memory
• During memory TX or polling RX
• The handset is off hook
• An original is in the ADF
• The ADF is open
Off Stand-by mode
The system +5V is still supplied to all components. When the machine detects a
ringing signal or receives a stream of data for a print job, the +24V supply is
activated and the machine automatically prints the incoming message or executes
the print job.
Off Mode
The system +5V supply also turns off. However, +5VE (+5V for energy saver
mode) is still activated. When the machine detects a ringing signal, off-hook signal,
or receives a print job, the machine returns to the Off Stand-by mode and the
system +5V and +24V supplies are activated.
Returning to stand-by mode
The machine returns to stand-by mode when the operation switch is pressed. The
recovery time is about 10 s.
