• Code: SC723-44
• Description: Stapler Motor Error (Internal Finisher: Non-Staple Bind) When the stapler drive HP sensor was not turned off while predetermined seconds applied to the stapler motor with the HP sensor turned on. When stapler drive HP sensor was not turned on while predetermined seconds applied to the stapler motor with the HP sensor turned off. The STM driver error detection is started after reset, and predetermined seconds error signal is detected. This SC will be issued when the above phenomenon repeated 2 times.
• Causes: • Stapler Motor failure • Connector disconnected • Stapler Motor overload • Stapler HP sensor error • Harness short-circuit • Circuit board failure • Excess current • Abnormal temperature
• Remedy: • Check the connection • Replace the motor/sensor • Replace the harness • Replace the circuit board

• Code: SC723-71

When shift HP sensor was not turned on while predetermined seconds applied to the shift motor with the HP sensor turned off. The STM driver error detection is started after reset, and predetermined seconds error signal is detected. This SC will be issued when the above phenomenon repeated 2 times.
• Causes: • Shift Motor failure • Connector disconnected • Shift Motor overload • Shift HP sensor error • Harness short-circuit • Circuit board failure • Excess current • Abnormal temperature
• Remedy: • Check the connection • Replace the motor/sensor • Replace the harness • Replace the circuit board
