6.8.8 ENERGY SAVER MODE

When the machine is not being used, the energy saver feature reduces power
consumption by switching off the fusing lamps. This machine has two energy saver
modes.
Level 1 Energy Saver Mode
The default of the level 1 energy saver mode is "Off." If the user enables it, the
level 1 energy saver mode starts 30 seconds after the machine has completed a
print. In this mode, the fusing lamps are intermittently turned on and off to keep the
heating roller at 100°C and pressure roller at 130°C.
The machine leaves this mode when one of the following happens:
• Print command received from a PC
• Any cover opened and closed
• Any operation panel key pressed
Level 2 Energy Saver Mode
The level 2 energy saver mode starts after the machine has been idle for a certain
time. This time is specified by a user tool as listed below. During the level 2 energy
saver mode, both lamps are off.
• Off (energy saver mode never activates)
• 5 minutes
• 15 minutes
• 30 minutes
• 45 minutes
• 60 minutes (default)
When the machine is in this mode, the machine turns off +24V, +12V, and +5V
lines. However, only +5VE lines, for the controller and GAPCI (voltage monitoring
ASIC) on the BCU, are still active.
The machine leaves this energy saver mode when one of the following happens:
• Print command received from a PC
• Any operation panel key pressed
NOTE: The machine does not leave the level 2 energy saver mode when covers
are opened and closed, because the CPU on the BCU is not active.
