The idle logout period can be changed on the device Web UI. The time before the logout depends on the Touch User Interface System Timeout setting on the printing device's web user interface. Every touch of the device touch panel display prolongs this timeout.
Log on to the printing device's web user interface as an administrator.
On the System tab, click Timeouts. The Timeouts dialog box opens.
Under Reset Device Control Panel, set System Timeout to the preferred value (between 10 and 900 seconds), and click OK.
