Sleep and Auto Sleep
Sleep
To enter Sleep, press the [Power] key. Touch panel and all indicators on the operation panel will go out to save a
maximum amount of power except the Main Power indicator. This status is referred to as Sleep.
If print data is received during Sleep, the print job is performed while the touch panel remains unlit.
When using the optional fax, received fax data is printed out while the operation panel also remains unlit.
• Press the touch panel or any key on the operation panel.
The machine will be ready to use within 20 seconds for 3051ci, 20 seconds for 3551ci, 28 seconds for 4551ci, and 30
seconds for 5551ci.
Note that ambient environmental conditions, such as ventilation, may cause the machine to respond more slowly.
Auto Sleep
Auto Sleep automatically switches the machine into Sleep if left idle for a preset time in the Low Power Mode.
The default preset time are 30 minutes for 3051ci, 45 minutes for 3551ci, and 60 minutes for 4551ci/5551ci.
To change the preset sleep time, refer to Sleep Timer
on page 8-55.
Sleep Level (Energy Saver)
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 on page 8-55.
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.
NOTE
If the optional network interface kit and Fiery controller are installed, Energy Saver cannot be specified.
