SC724-85 D Stopper Solenoid (SOL3) Error
• When the Stopper Solenoid (SOL3) lowers the actuator down to the
topmost paper of the paper stack, the Remaining Paper Sensor (S40)
turns OFF. (The first four times are displayed as jams. An SC is displayed
when it is repeated five times.)
• Stopper Solenoid (SOL3) defective
• Connector disconnected
• Motor overload
• Remaining Paper Sensor (S40) defective
Check if the SC occurs by turning the main power OFF then ON. If the SC
occurs again, do the following steps. Check if the SC reoccurs by cycling the
power after each step.
1. Check if the harness between the finisher Main Board (PCB25) and the
Remaining Paper Sensor (S40) / Stopper Solenoid (SOL3) is not stripped
or entrapped.
Replace the harness if there are any defects.
2. Check if there is any unusual odor from the Remaining Paper Sensor
(S40) or any problem with its appearance.
Replace it if there are any defects.
3. Check if there is any unusual odor from the Stopper Solenoid (SOL3) or
any problem with its appearance.
Replace it if there are any defects.
4. Replace the finisher Main Board (PCB25).
