• Code: SC724-38
• Description: Paper Press Motor Error (Internal finisher) • When the paper press HP sensor is ON and the paper press motor is driven for T14 msec, the HP sensor does not switch OFF (1st time is jam notification, 2nd time is SC notification). • When the paper press HP sensor is OFF and the paper press motor is driven for T15 msec, the HP sensor does not switch ON (1st time is jam notification, 2nd time is SC notification).
• Causes: • Motor defective • Connector disconnected • Motor overload • Home position sensor error • Paper surface sensor error (*SC724-38, 70 only) • Staple jam (*SC724-86 only)
• Remedy: • Reset the connector • Replace the motor • Replace the sensor • Replace the harness • Remove the staple jam (*SC724-86 only)

• Code: SC724-42
• Description: Stapler Displacement Movable Motor Error (Internal finisher) • Sifter stapler displacement HP sensor ON, even when the stapler displacement motor is driven for T9 msec, the HP sensor does not switch OFF (1st time is jam notification, 2nd time is SC notification). • After stapler displacement HP sensor OFF, even when the stapler displacement motor is driven for T10 msec, the HP sensor does not switch ON (1st time is jam notification, 2nd time is SC notification).
• Causes: • Motor defective • Connector disconnected • Motor overload • Home position sensor error • Paper surface sensor error (*SC724-38, 70 only) • Staple jam (*SC724-86 only)
• Remedy: • Reset the connector • Replace the motor • Replace the sensor • Replace the harness • Remove the staple jam (*SC724-86 only)

• Code: SC724-70
• Description: Shift Tray Ascent/Descent Motor Error (Internal finisher) • During ascent from paper surface sensor ON, even after T11 msec elapses, the paper surface sensor does not switch OFF (1st time is jam notification, 2nd time is SC notification). • During descent from paper surface sensor OFF, the paper surface sensor does not switch ON even after T12 msec elapses (1st time is jam notification, 2nd time is SC notification). • During descent to the packing position, the full sensor does not switch ON even if T13 msec elapses.
• Causes: • Motor defective • Connector disconnected • Motor overload • Home position sensor error • Paper surface sensor error (*SC724-38, 70 only) • Staple jam (*SC724-86 only)
• Remedy: • Reset the connector • Replace the motor • Replace the sensor • Replace the harness • Remove the staple jam (*SC724-86 only)

• Code: SC724-80
• Description: Shift Motor Error (Internal finisher) • When the shift roller HP sensor is ON, the HP sensor does not switch OFF even when the shift roller motor is driven for T5 msec (1st time is jam notification, 2nd time is SC notification) • When the shift roller HP sensor is OFF, the HP sensor does not switch ON even when the shift roller motor is driven for T6 msec (1st time is jam notification, 2nd time is SC notification).
• Causes: • Motor defective • Connector disconnected • Motor overload • Home position sensor error • Paper surface sensor error (*SC724-38, 70 only) • Staple jam (*SC724-86 only)
• Remedy: • Reset the connector • Replace the motor • Replace the sensor • Replace the harness • Remove the staple jam (*SC724-86 only)

• Code: SC724-86
• Description: Stapler Motor Error (Internal finisher) • HP sensor does not switch OFF even when the stapler motor is driven for T7 msec after the stapler HP sensor switches ON (1st time is jam notification, 2nd time is SC notification). • HP sensor does not switch ON even when the stapler motor is driven for T8 msec after the stapler HP sensor switches OFF (1st time is jam notification, 2nd time is SC notification).
• Causes: • Motor defective • Connector disconnected • Motor overload • Home position sensor error • Paper surface sensor error (*SC724-38, 70 only) • Staple jam (*SC724-86 only)
• Remedy: • Reset the connector • Replace the motor • Replace the sensor • Replace the harness • Remove the staple jam (*SC724-86 only)

• Code: SC761-03
• Description: Protection Device Intercept Error 5V Fuse blowout occurs due to over current during power injection (output detected for longer than 2 seconds).
• Causes: • Over current of bridge unit motor • Over current due to short-circuit in PCB
• Remedy: • Replace the bridge unit • Replace the PCB

• Code: SC761-04
• Description: Protection Device Intercept Error 24V Fuse blowout occurs due to over current during power injection (output detected for longer than 2 seconds).
• Causes: • Over current of bridge unit motor • Over current due to short-circuit in PCB
• Remedy: • Replace the bridge unit • Replace the PCB

• Code: SC780-01
• Description: Bank 1 (Upper optional paper tray) Protection Device Intercept Error When original source of 5V power supply is ON, protection device intercept of 24V power system is detected.
• Causes: In 24V power supply system: • Motor defective • Solenoid defective • Harness short- circuit
• Remedy: • Replace the PCB • Replace the short-circuited part (harness, motor, solenoid)
