The printer has the ability to print many types of internal pages without being connected to a computer or to a network.
The most useful of these is the Menu Settings Page (also known as an Internal Test Page). This page, or set of pages, shows all the current user settings and code levels on the printer. This includes the page count, the amount of toner left in the cartridges, the paper settings on the various trays, and what extra options are installed on the printer. The menu settings page is also useful as a reference for locating items in the printer menu system.
