Power Supply Operations
Sleep Mode (Power-saving Feature)
This machine is provided with a power-saving feature that switches to a low-power "sleep mode" when a fixed
interval passes with no operation. The factory default for the time after which the machine switches to sleep
mode is 30 minutes. When the machine is in the sleep mode, the sub power switch flashes slowly. Using the oper-
ation panel or performing operations such as sending print data from the computer restores the machine to its
normal mode.
This sleep mode setting can be changed. However, we recommend setting the activation time for sleep mode to 30
minutes or less to reduce power consumption and prevent problems such as overheating.
