Fatal Sc Codes/Fusing Related Errors; Executing Fusing Sc Reset - Ricoh SP 150 Field Service Manual

5. Troubleshooting
• Before deciding to replace electrical components (PCB/PSU/HVP), always check the harnesses to
make sure that the problem was not caused by a loose connection.
• Before deciding to replace a motor or a sensor, always check around the motor or sensor feelers to
make sure that there is no physical obstruction such as paper scraps or things that have fallen into
the machine (for example, paper clips or pins).

Fatal SC Codes/Fusing Related Errors

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.
