10.5 ENERGY SAVER FUNCTION

When the copier is not in use, the energy saver function reduces the power
consumption by decreasing the fusing temperature. The energy Saver
indicator turns on and all the other indicators turn off.
For this copier, the energy saver function cannot be entered manually. To
access this function, SP78 (Auto Energy Saver Mode) must be set to "1". And
since this function is applied at the time when the machine enters the auto
reset, SP15 (Auto Reset Time) must be set to "0" or "1" as well.
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 exits the energy saver mode upon the following actions.
1. Pressing any key except the Start key.
2. Setting copy paper on the by-pass feed table.
3. Opening the optional DF or setting an original on it.
4. Opening and closing the front cover.
5. Turning the main switch OFF/ON.
