Automatically Display Error Screens

If On, the panel automatically displays any existing printer-related IR after the printer remains inactive on the home
screen for a length of time equal to the Screen timeout setting in the Timeouts section of the General settings menu.
Any IR that appears on the display will give the user the option of returning to the home screen without clearing it.

screen, any existing IR will again appear after the printer remains inactive for a length of time equal to the Screen
timeout setting.
