Reset Menu Use Reset Menu function with caution. It can result in loss of buffered page data or printer configuration data. Reset Menu is activated by holding down both [Shift] and [Menu] for up to 10 seconds until RESET=MENU* appears. Use [+] or [-] to cycle through items and [Enter] to select the item. The reset is executed by pressing [On Line]. Table 3-2 Reset Menu Functions [Reset] (and Menu of Resets) A reset ([Shift] + [Menu]) displays a 07 RESET, clears the printer's page buffer, removes all temporary typefaces and macros, and makes the current user-established defaults "permanent." They will be the default values until they are changed by the user. To access the Menu of Resets, hold down both [Shift] and [Menu] for about 10 seconds until RESET=MENU* appears in the display panel. Use [-] to cycle through the display choices, and [Enter] to select the option. Execute the reset by pressing [On Line]. The printer responds with a reset message for the choice selected. The three RESET= choices are: MENU* clears the page buffer, removes all temporary personality data such as downloaded typefaces, and resets all printing environment parameters (such as number of copies, paper size, etc.), and sets user-selected defaults (such as MP tray default configuration) to their factory defaults. Certain items, such as the display language or I/O configuration, are not reset. RESET=MENU clears only the active I/O input buffer. ACTIVE I/O clears the page buffer, removes all perishable personality data such as temporary typefaces, and clears the input and output buffers for the active I/O only. ALL I/O clears the page buffer, removes all perishable personality data such as temporary typefaces, and clears the input and output buffers for all I/Os. * indicates factory default.
