11.4 ENERGY SAVER FUNCTION
When the copier is not in use, the energy saver function reduces the power
consumption by decreasing the fusing temperature.
When the Energy Saver/Clear Modes key is pressed for over 1 second, the
copier goes to the energy saver mode. The Energy Saver indicator turns on
and all the other indicators turn off.
The energy saving ratio can be selected by SP86 as shown in the following
table.

NOTE: The energy saving ratio in the above table are standard values
measured in laboratory tests under controlled conditions. The actual
ratios will vary depending on environmental conditions, copy modes,
power supply conditions and measurement instruments.
The greater the energy saving ratio is, the longer the waiting time until the
copier returns to the ready condition.
The copier returns to the ready condition (after a warm-up time) by the
following actions:
1. Pressing any key except the Start key,
2. Opening the manual feed table or setting copy paper on it,
3. Opening the platen cover (FT4222 copier only),
4. Opening the DF or setting original on it.
When the auto energy saver mode (SP78) is selected, the copier
automatically goes to the energy saver mode at the auto reset time selected
by SP15.
