• Code: SC508-00
• Description: By-pass bottom plate operation error
• Causes: The signal from the by-pass bottom plate position sensor has not changed (the signal has not changed from ON to OFF or vice versa) for 4 seconds or more after the start of reverse Paper Feed Unit rotation, If the error is detected three times in succession, the SC number is displayed on the operation panel. • By-pass bottom plate sensor connector disconnected or other error • By-pass bottom plate sensor feeler stuck or other error
• Remedy: • Turn the main power OFF and then ON. • Check and replace the by-pass bottom plate sensor connector connection. • Replace the by-pass bottom plate sensor feeler. • Replace the Paper Feed Motor. • Replace the harness. • Replace the BICU.

• Code: SC520-00
• Description: Main motor error
• Causes: When the main motor is driven, the lock (state of rotation) signal is checked every 100 milliseconds. If the machine detects the lock signal in the High status 20 times in succession, it reports this error. • The main motor incurs too much load from a defective unit. • The main motor is defective.
• Remedy: Replace the defective unit or the motor
