• Code: SC351
• Description: Developer Fill Error: M
  The PCU failed to fill with developer from the developer bottle when SP3814-1 was executed.
• Causes: • Developer bottle not set correctly • Developer in the bottle is clogged and not flowing Note: For detailed information about how to handle problems developer filling, see "Handling Problems with Developer Filling" under "PCU" in Section 3.

• Code: SC352
• Description: Developer Fill Error: C
  The PCU failed to fill with developer from the developer bottle when SP3814-1 was executed.
• Causes: • Developer bottle not set correctly • Developer in the bottle is clogged and not flowing Note: For detailed information about how to handle problems developer filling, see "Handling Problems with Developer Filling" under "PCU" in Section 3.

• Code: SC353
• Description: Developer Fill Error: Y
  The PCU failed to fill with developer from the developer bottle when SP3814-1 was executed.
• Causes: • Developer bottle not set correctly • Developer in the bottle is clogged and not flowing Note: For detailed information about how to handle problems developer filling, see "Handling Problems with Developer Filling" under "PCU" in Section 3.

• Code: SC360
• Description: TD sensor (Vt high) error: K
  The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds 0.5V for 10 counts.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and PCU defective • Defective TD sensor, replace the PCU Note: The TD sensor cannot be replaced independently. The PCU must be replaced if the TD sensor is defective.

• Code: SC361
• Description: TD sensor (Vt high) error: M
  The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds 0.5V for 10 counts.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and PCU defective • Defective TD sensor, replace the PCU Note: The TD sensor cannot be replaced independently. The PCU must be replaced if the TD sensor is defective.

• Code: SC362
• Description: TD sensor (Vt high) error: C
  The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds 0.5V for 10 counts.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and PCU defective • Defective TD sensor, replace the PCU Note: The TD sensor cannot be replaced independently. The PCU must be replaced if the TD sensor is defective.

• Code: SC363
• Description: TD sensor (Vt high) error: Y
  The Vt value of the black, magenta, cyan, or yellow TD sensor exceeds 0.5V for 10 counts.
• Causes: • Black, magenta, cyan, or yellow TD sensor disconnected • Harness between TD sensor and PCU defective • Defective TD sensor, replace the PCU Note: The TD sensor cannot be replaced independently. The PCU must be replaced if the TD sensor is defective.

• Code: SC364
• Description: TD sensor (Vt low) error: K
  The Vt value of the black, magenta, cyan, or yellow TD sensor is below 0.5V for 10 counts.
• Causes: • TD sensor harness disconnected, loose, defective • A drawer connector (located on the rear of a development unit) disconnected, loose, defective • TD sensor defective, replace the PCU Note: The TD sensor cannot be replaced independently. The PCU must be replaced if the TD sensor is defective.
