Dispose of used batteries according to the instructions.
10.4.3 Energy-Saving Function
10.4.3.1 Overview
1. Standby Mode
The machine is in operation or is ready to start operation, with all its loads supplied with power.
2. Power Save Mode
The machine deceases the control temperature while the fixing assembly is in a standby state according to
the selected power save rating (variable through 'change power save mode' in user mode; default: -10%),
thus decreasing the power consumption.
Conditions Initiating a Shift from Standby Mode (standby -> power save)
- press on the Power Save key
Conditions Initiating a Shift Back to Standby Mode (power save -> standby)
- press on the Power Save key
- press on the control panel power switch
3. Low Power Mode
The machine keeps the temperature of the fixing assembly low (140 deg C), with the reader unit and the
printer unit supplied with a reduced level of power.
Conditions Initiating a Shift from Standby/Power Save Mode (standby -> low power)
- after a specific period of time in standby/power save mode (variable through 'low power mode shift in-
terval'; default: 15 min)
