1. SC Codes
Self-Diagnostic Mode
Service Call Conditions
At job end or when the machine is switched off, both sides of the ITB unit are lowered and
separated from the drums.
However, after a power failure or accidental disconnection of the power cord, or after a
machine issues an SC code after a malfunction, both or one side of the ITB may remain up
against the drums.
To avoid damage to the ITB, both sides of the ITB must be checked and lowered before the
ITB unit can be pulled out of the unit.
The ‘SC Table’ section shows the SC codes for controller errors and other errors. The latter are put into
four types. The type is determined by their reset procedures. The table shows the classification of the
SC codes.

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: 0: Manual reboot).
SP descriptions: SP5-875-001 (SC automatic reboot: Reboot Setting)
Enables or disables the automatic reboot function when an SC error occurs.
0: The machine reboots automatically when the machine issues an SC error and logs the SC error
code. If the same SC occurs again, the machine does not reboot.
1: The machine does not reboot when an SC error occurs.
The reboot is not executed for the pattern A or C.
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: 1
"OFF").

1.SC Codes
9
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).
Screen display during reboot
Status display on the current screen
Post-processing ...... Post-processing during printing, etc.
Automatic reboot .... After operation end

Until automatic reboot
Reset key (Reboot key)

# 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 @Remote 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 post-
processing 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
See the flowchart below.

SC Manual Reboot
When the automatic reboot is disabled in SP5-875-001 (SC automatic reboot setting), the user reboots
the machine manually. See the flowchart below.
