Chapter 2 Operation
The 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 the sleep
mode is 30 minutes.
You can change the setting for the time of the shift to the sleep mode. You can also switch off the power-saving
feature.
☞ p 79 "Setting the Interval until Activation of the Sleep Mode"
☞ p 80 "Deactivating the Sleep Mode"
When the machine is in the sleep mode, the POWER light flashes slowly and the heating devices stop.
Using the control panel or performing operations such as sending printing data from the computer (when media
is loaded) restore the machine to its normal mode.
To reduce power consumption and prevent problems such as overheating, we recommend leaving the power-
saving feature on and setting the activation time for the sleep mode to 30 minutes or less.
