5022-xxx Size Sensing Turns the automatic size sensing for print media input sources either to Auto or Off. Selections include Tray 2 Sensing, if the tray is installed, Auto (default), and Off. This is a two-level menu that displays only those print media sources which support automatic size sensing. Panel Menus Lets the system support person enable or disable the operator panel menus. Selecting Enable (the default) prevents users from changing values for the printer. Disable allows users to changes the values. This menu item only appears when the PJL PASSWORD Environment variable is set to 0. PPDS Emulation Activates or deactivates the Personal Printer Data Stream (PPDS) emulation language. This menu item only appears if the PPDS interpreter is available. Download Emuls Lets the system support person turn the download emulator off. This menu item only appears if one download emulator is installed. The only selection is Disable. An Enable value is unnecessary because the printer automatically re-enables all download emulators after two instances of a power-on reset for the printer. To re-enable these emulators, a user would perform another power-on reset after exiting the CONFIG MENU. Demo Mode Lets marketing personnel or merchandisers demonstrate the printer to potential customers by printing the demo page. Selections include Deactivate (default) and Activate. Select Deactivate to turn Demo Mode off; or select Activate to turn Demo Mode on. Factory Defaults Sets the majority of printer values back to their factory default settings. Warning: This selection cannot be reversed, so this operation should only be used as a last resort to fix any printer problem. When factory default settings are restored: • All downloaded resources (fonts, macros, symbol sets) in the printer memory (RAM) are deleted. • All menu settings return to the factory default setting except: - The Display Language setting in the "Setup" Menu. - All settings in the Parallel Menu, Serial Menu, Network Menu, Infrared Menu, LocalTalk Menu, and USB Menu. Selections are Restore Base and Restore Network. The Restore Network value only appears on printer models that have integrated network support. Restoring Factory Defaults appears on the operator panel while factory defaults are restored. 3-22 Service Manual
