Fatal SC codes are related to problems that occur in the fusing unit. Fusing related errors require special handling because there is a risk of fire.
Once a fatal error occurs, the machine cannot be used until the problem has is solved.
When SC 559 Detection is enabled, the machine will shut down after three consecutive fusing jam errors. For safety, this setting should remain enabled.
When a fatal error (fusing related SC code) occurs, the machine cannot be operated until the service technician releases the error by selecting [On] for FusingSCReset.
After solving the problem that caused the fatal SC code to be issued, the service technician must execute [FusingSCReset] in order to recover full operation of the machine. Otherwise the machine will continue to issue the same SC code even after the problem has been solved.
