Self-Diagnostic Mode
D255/D256/M281/M282 6-2 SM
 When an ordinary SC (type D) is generated, an automatic reboot is performed. When an
event is reported by the customer support system, even in the event of an ordinary SC,
reboot is not performed. During automatic reboot, a confirmation screen is displayed after
the reboot.
 When automatic reboot occurs twice continuously, an SC is displayed without rebooting,
and logging count is performed. Also, when an SMC print is output, an * mark is added
alongside the SC number for clarity.
 Automatic reboot can be enabled or disabled with SP5-875-001 (SC automatic reboot
setting) (default value: ON).
6.1.2 SC LOGGING
When an SC is generated, the "total count value when the SC is generated" and the "SC code"
are logged. However, if the total count value during the SC is the same as last time, logging is not
performed.
Logged data can be checked by outputting an administrative report (SMC print). The SC history is
logged up to the last 10 entries, and if there are more than 10 entries, data are progressively
deleted starting from the oldest.
6.1.3 SC AUTOMATIC REBOOT (MP 501/601)
When an ordinary SC (pattern D) is generated, automatically reboot is performed. Automatic
reboot or reboot by user operation can be set by SP5-875-001 (SC automatic reboot setting out)
(default value: 0 "Automatic reboot").
When a type D occurs, automatic reboot is done or the machine display asks the customer if it can
reboot. However, when the SC occurs twice in a short time, the machine sends a report to the
@Remote server without rebooting. This is because just rebooting may not be a good solution if
an SC occurs twice.
When an automatic reboot is performed, a confirmation screen is displayed after reboot. The
confirmation screen can be cancelled by pressing the [OK] key (display is not cancelled only when
the main power switch is switched OFF to ON).
