5.5 Low Power Mode

In low power mode, only the +24V power supply remains off; the level of power con-
sumption for the reader unit and the printer unit is reduced for low power consumption.
5.5.1 Shift from Standby Mode (standby → low-power)
A shift is made from standby mode to low power mode under the following conditions:
• Low power mode is selected on the control panel.
• Standby mode has continued for a specific period of time, selected in user mode.
5.5.2 Shift to Standby Mode (low power → standby)
A shift is made from low power mode to standby mode under the following conditions:
• The control panel power switch (soft switch) is on.
• PDL data is received from the network or parallel power. (Electrically, the control
panel is off as in standby mode.)

5.6 Sleep Mode

In sleep mode, only the +3.3V all-night (3.3 VB) power supply is powered.
The CPU on the main controller PCB stops the programs, thereby saving power (the pro-

This mode is used only when the machine is used as a printer equipped with a network
print option/PDL print option.
