Saving Power with the PowerSave Feature
To reduce the amount of power it consumes, your printer has a
PowerSave feature.  PowerSave shuts down the fuser after the printer
has been idle for a specified amount of time.
The PowerSave feature is both adjustable and optional. You can set
PowerSave to start after the printer has been idle 15 minutes, 30
minutes, 1 hour, 2 hours, or 3 hours, or you can turn PowerSaveOFF.
By default, PowerSave is ONand the amount of idle time is set to 30
minutes.
When the printer is in PowerSave mode, the printer control panel
displays the message POWERSAVE ON, which will replace the READY
message on the printer control panel.
NoteError messages override the PowerSave message. When an error
condition is present, the printer displays the error message. At the
appropriate time, the printer goes into PowerSave, but the error message
continues to be displayed.
The printer automatically comes out of PowerSave when you send a
print job to the printer, press a printer control panel key, load or remove
paper, or open the top cover.
When the printer comes out of PowerSave, the printer control panel
displays the message WARMING UP, as the fuser warms to operating
temperature. The longer the printer was in PowerSave, the longer it
takes the fuser to warm up.  For example, after the printer has been in
PowerSave overnight, it can take up to 45 seconds for the fuser to warm
up.
