SC360-01 D TD Sensor (Vt high) Error 1: K
SC360-02 D TD Sensor (Vt high) Error 1: C
SC360-03 D TD Sensor (Vt high) Error 1: M
SC360-04 D TD Sensor (Vt high) Error 1: Y
•
count is higher than the threshold which detects no developer
•
count is lower than the upper/lower target thresholds three
consecutive times.
• TD Sensor (mu sensor, sensor) failure
• Harness loose or disconnected
• An old PCDU may be installed
Troubleshooting procedure:
Check if the SC occurs by turning the 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 all the related connectors are connected.
If not good, reconnect the connectors.
2. Check the PCDU (e.g. Gear/harness disconnected? Heat protection
seal removed? Using an old PCDU?).
If not good, replace the PCDU.
3. Check whether the TD Sensor (S14) is deformed, scratched,
damaged or has dust sticking to it.
4. Check the TD Sensor (S14) harnesses, and the harness between the
mainframe and PCDU.
If not good, replace the harness.
5. Replace the BiCU (PCB1).

SC361-01 D TD Sensor (Vt) Upper Limit Error: K
SC361-02 D TD Sensor (Vt) Upper Limit Error 1: C
SC361-03 D TD Sensor (Vt) Upper Limit Error 1: M
SC361-04 D TD Sensor (Vt) Upper Limit Error 1: Y
The machine detects that Vt (TD sensor output, SP3-210-001 to 004) is
higher than the upper limit threshold for the specified consecutive times.
• TD Sensor (S14) connector is disconnected
To check if the issue is resolved:
1. Cycle the power OFF/ON.
2. Feed one sheet of paper.
