Sleep Rules (models for Europe)
You can set whether sleep mode operates for each function. When the machine enters sleep mode, it cannot perform
printing from a computer connected by USB cable. In addition, it takes longer for the machine to wake and return to
normal operation. Also, the ID card cannot be recognized.
For more information on Sleep Rules settings, refer to Sleep Rules (models for Europe) on page 8-55.
Sleep Level (Energy Saver) (models except for Europe)
This mode reduces power consumption even more than normal Sleep mode, and allows Sleep Mode to be set
separately for each function. Printing from a computer connected with a USB cable is not available while the machine is
asleep. The time required for the machine to wake up from power save mode and resume normal operation will be
longer than for normal Sleep Mode.
For more information on Energy Saver Mode settings, refer to Sleep Level (models except for Europe) on page 8-56.
Energy Saver Recovery Level
This machine can reduce power consumption when recovering from Energy Saver Mode.
For EnergySaver RecoveryLevel, "Full Recovery", "Normal Recovery" or "Power Saving Recovery" can be selected.
The factory default is "Normal Recovery".
For more information on Energy Saver Mode settings, refer to EnergySaver RecoveryLevel on page 8-56
