If the printer is left idle for some time, it goes into sleep mode and switches off
the front-panel display.
To change the time that elapses before sleep mode, tap
Power options > Printer sleep. You can set a time between 5 and 60 minutes; the
default time is 15 minutes. This time includes 5 minutes in dim mode.
The printer can be woken from sleep mode by the power button, by sending a
print job, by opening a cover, or by tapping the front panel.
You can use the printer's auto-off feature to turn the printer off automatically.
Setting it to 2 hours turns the printer off after 2 hours of inactivity. In this way,
you can save more energy.
The auto-off feature is automatically disabled when the printer is connected to
the network, to avoid inconveniencing network users. Auto-off can be re-enabled
if required.
Front-panel error codes
The printer may occasionally display a system error, consisting of a numerical
code of 12 digits followed by the recommended action that you should take.
In most cases you will be asked to restart the printer, because when the printer
starts it can diagnose the issue better and may be able to fix it automatically. If
the problem persists after restarting, you should contact your HP support
representative and be ready to give the numerical code from the error message.
