Pattern	Display	How to reset	SC call or SC alarm in customer support system
A	The SC is displayed on the operation panel, and the machine cannot be used (safety-related SC).	Execute CE reset SP mode, and switch main power from OFF to ON. • When canceling a fusing unit SC, (SC544-00/ SC554-00/ SC564-00/ SC574-00), perform part replacement in accordance with the above procedure.	Occurrence & alarm count → Immediate alarm
B	When a function is selected, the SC is displayed on the operation panel, and the machine cannot be used (down­time mitigation).	Switch the user reset power key or main power switch OFF to ON.	Occurrence & alarm count → Power OFF→ ON → Alarm count and alarm only if recurrence
C	No display on the operation panel, and use is permitted.	Count only logging.	Occurrence → Logging count & alarm count
D	The SC is displayed on the operation panel, and the machine cannot be used (machine-error SC).	Switch user reset power key or main power switch OFF to ON.	Occurrence & alarm count → Power supply OFF→ON → Alarm count and alarm only if recurrence

Note:

• 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).

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.

SC automatic reboot

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").

However, when a NRS report is performed, a reboot is not performed even in the case of the corresponding SC. 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).

Screen display during reboot

• Status display on the current screen
  • Post-processing ...... Post-processing during printing, etc.
  • Automatic reboot .... After operation end
• Reset key (Reboot key)
  Key to perform reboot
  # Cancel key is not displayed.
• Turn on spanner LED (same as when an SC is generated).

Operation during SC reboot

• Timing of SC reboot When NRS is enabled, and when a NRS alarm*1 is not generated, the corresponding SC is the object of an automatic reboot.
  *1 NRS alarm: Issued when an ordinary SC (type D) is generated twice while the total counter counts 10 times.
• Time to automatic reboot
  Reboot is performed 30 seconds after an engine reboot is possible, after the end of postprocessing during printing, etc. At that time, a reboot is performed even if the MFP is operating. The engine does not start process control when a reboot is possible.
• Automatic reboot

Controller self-diagnosis includes 3 types, i.e., "ordinary self-diagnosis", "detailed self-diagnosis", and "SC detection". "Ordinary self-diagnosis" is diagnosis performed for every power ON, and "detailed self-diagnosis" is diagnosis treated as part of the service tools. "SC detection" detects mechanical faults when power is switched on or when the machine is operating.

Detailed self-diagnosis – Method

1. After attaching the option "extension 1284 board" to the controller board, connect the conversion connector provided.
2. Set a loop back connector in the reference Centronics I/F.
3. Press the main power supply switch while simultaneously pressing the "#" and "./* key. The display changes to the following screen, and self-diagnosis starts.
4. After the end of detailed self-diagnosis, a "Self-diagnosis results report" is automatically printed.

Note:

• If a Centronics loopback connector is not fitted, a Centronics diagnosis error (SC 835) is generated.
• Loop-back connector: G0219350
