Change the device settings

You can change the power save time and prompt delay time settings on your HP all-in- one so that it behaves according to your preference. You can also restore the device settings to what they were when you purchased your device. This will erase any new defaults you have set.

Set the power save time

The light bulb in the scanner of your HP all-in-one remains on for a specified period so that the HP all-in-one is immediately ready to respond to your request. When the

HP all-in-one has not been used within that specified period, it turns the light bulb off to preserve power. You can exit this mode by pressing any button on the control panel.

Your HP all-in-one is automatically set to enter power save mode after 12 hours. Follow these steps if you want the HP all-in-one to enter this mode earlier.
