My mailstation acts differently on a reset.
It first shows a message stating scanning memory, and has a fillup bar. (not sure of the technical term but the type of graphic filling up a small rectangle)
Then it give a menu entitled "Reset System Data" with the choices
Clear Email Data
Clear Address Book Data
Clear Daily Events Data
Clear All Data
Sounds like your's is quite different. Might be time to open it up. Its seven screws, plus unscrew the printer port.
