What happens in energy saver modes 1 and 2
The behaviour in these levels is the same also (fusing lamp at low
temperature). However, there are two extra cases for leaving energy saver
mode:
•
Ringing signal detected
•
NCU off-hook (the machine starts to dial a fax number)
If the auto shut off timer runs out while the main switch is still on, the machine
enters energy saver level 4.
What happens in energy saver mode 4
In this mode, the fusing lamp switches off. Also, the system +5V supply
switches off. Only the +5VE supply stays on, so that the machine can monitor
the ADF, the telephone line, and the operation panel.
The machine recovers to standby mode in the same conditions as for level 1
or 2. For example, incoming faxes and printer jobs will be printed. The
recovery time from this level is the same as for recovery from auto shut off
mode.
Entering night mode
If the main switch is turned off while the machine is in standby or energy
saver mode 1 or 2, the machine enters night mode 1.
If the main switch is turned off while the machine is energy saver mode 4, the
machine enters night mode 2.
- Night mode 1 -
The fusing lamp turns off. However, the system +5V is still supplied to all
components. When the machine detects a ringing signal, the machine
automatically prints the incoming message.
From night mode level 1, the machine goes to night mode level 2 when the
auto shut off timer runs out.
- Night mode 2 -
The system +5V supply also turns off. However, +5VE (+5V for the energy
saver) is still activated. If the machine detects a ringing signal or off-hook
signal, the machine goes back to night mode level 1. At this time, the system
+5V supply is activated. Then the machine receives the incoming message
and prints it.
The machine leaves night mode and returns to standby mode if the main
switch is turned on.
