• Causes: • TD sensor harness disconnected, loose, defective • A drawer connector disconnected, loose, defective • TD sensor defective
• 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. 3. Replace the defective PCDU.

• Code: 362-04
• Description: TD sensor (Vt low) error 2: Y
  The Vt value of the black, magenta, cyan, or yellow TD sensor is below the specified value with SP3-020-004 (default: 0.5V) for 10 counts.
• Causes: • TD sensor harness disconnected, loose, defective • A drawer connector disconnected, loose, defective • TD sensor defective
• 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. 3. Replace the defective PCDU.

• Code: 370
• Description: ID sensor adjustment error
  When the Vsg error counter reaches "3", the machine detects "SC370". The Vsg error counter counts "1" when the Vsg detected by ID sensor is more than the value (default: 4.5V) specified with SP3-324-005 or less than the value (default: 3.5V) specified with SP3-324-006.
• Causes: • Dirty or defective ID sensor • ID sensor detection surface dirty
• Remedy: 1. Check the harness of the ID sensor. 2. Clean or replace the ID sensor. Note: After replacing the ID sensor, input the ID sensor correction coefficient with SP3362-013 to -018. For details, refer to "ID sensor board" in the Replacement and Adjustment section. 1. Replace the BCU. 2. Replace the ITB unit.

• Causes: • Dirty or defective drum gear position sensor
• Remedy: 1. Clean the drum gear position sensor. 2. Check the harness connection. 3. Replace the drum gear position sensor. 4. Replace the PCDU.

• Code: 390-02
• Description: Drum gear position sensor error: C
  The machine does not detect the drum position signal for 3 seconds at the drum phase adjustment.
• Causes: • Dirty or defective drum gear position sensor
• Remedy: 1. Clean the drum gear position sensor. 2. Check the harness connection. 3. Replace the drum gear position sensor. 4. Replace the PCDU.
