: In order to get more details about SC990 and SC991:
1) Execute SP7403 or print an SMC Report (SP5990) to read the history of the 10 most recent
logged errors.
2) If you press the zero key on the operation panel with the SP selection menu displayed, you
will see detailed information about the recently logged SC990 or SC991, including the
software file name, line number, and so on. 1) is the recommended method, because
