• Code: 314
• Description: AC charge output error [C]. The machine detects the AC charge output for each color 0.3 V or less for 0.2 seconds after the machine has started to detect the AC charge output.
• Causes: • Loosen or broken harnesses to the HVPS: C/B • Not set or broken PCDU • Defective HVPS: C/B
• Remedy: 1. Close the drum securing plate firmly. 2. Make sure that the PCDU terminal plate contacts the machine terminal plate closely at the front side. 3. Set correctly or replace the PCDU. 4. Replace the harnesses to the HVPS: C/B. 5. Replace the HVPS: C/B.

• Code: 325
• Description: Color development motor error The motor LOCK signal is not detected for more than two seconds while the motor START signal is on.
• Causes: • Color development motor slip due to an increase in the torque caused by connected components. • Defective motor.
• Remedy: 1. Adjust the torque properly by replacing or cleaning the PCDU. 2. Replace the PCDU. 3. Replace the development motor: CMY if load torque is normal.

• Code: 360
• Description: TD sensor (Vt high) error 1: K • The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 4.7V) with SP3020-002 twenty counts. • The [Vt - Vtref] value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 5.0V) with SP3020-001.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and development unit defective • Defective TD sensor.
• Remedy: 1. Check the black, magenta, cyan, or yellow TD sensor connector and harness between the TD sensor and PCDU for damage. 2. Check the drawer connector of the PCDU. 3. Replace the PCDU.

• Code: 361
• Description: TD sensor (Vt high) error 1: M • The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 4.7V) with SP3020-002 twenty counts. • The [Vt - Vtref] value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 5.0V) with SP3020-001.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and development unit defective • Defective TD sensor.
• Remedy: 1. Check the black, magenta, cyan, or yellow TD sensor connector and harness between the TD sensor and PCDU for damage. 2. Check the drawer connector of the PCDU. 3. Replace the PCDU.

• Code: 362
• Description: TD sensor (Vt high) error 1: C • The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 4.7V) with SP3020-002 twenty counts. • The [Vt - Vtref] value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 5.0V) with SP3020-001.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and development unit defective • Defective TD sensor.
• Remedy: 1. Check the black, magenta, cyan, or yellow TD sensor connector and harness between the TD sensor and PCDU for damage. 2. Check the drawer connector of the PCDU. 3. Replace the PCDU.

• Code: 363
• Description: TD sensor (Vt high) error 1: Y • The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 4.7V) with SP3020-002 twenty counts. • The [Vt - Vtref] value of the black, magenta, cyan, or yellow TD sensor exceeds the specified value (default: 5.0V) with SP3020-001.
