Power supply voltage detection
The product detects the power supply voltage that is connected to the product. The DC controller
monitors the POWER SUPPLY VOLTAGE (PSTYP100) signal and detects power supply voltage, whether
100V or 200V, to control the fusing operation properly.
Low-voltage power supply failure
The DC controller determines a low-voltage power supply failure and notifies the formatter when the
low-voltage power supply does not supply +24V.
Power Off condition
The DC controller brings the product to a power off condition by 24V POWER SUPPLY (24VRMT)
signal, 5V POWER SUPPLY (VC5VOFF) signal, 3V POWER SUPPLY (VC3VOFF) signal, and VOLTAGE
CONVERSION (PWRSAVE) signal.
The +5VA and +5VC signals which are converted into +3.3V and +3.3VA, are supplied under the
power off condition.
Auto on/Auto off mode
This feature conserves power after the product has been idle for an adjustable period of time. When
the product is in this mode, the control-panel backlight is turned off, but the product retains all settings,
downloaded fonts, and macros. The setting is disabled by default. The product enters this mode after a
60-minute idle time or by touching the sleep button.
