• Code: SC360-01
• Description: TD sensor adjustment error (K). During TD sensor initialization, the TD sensor output voltage (Vt) cannot be adjusted to the target range (target value ± 0.2V). Details: TD sensor initialization adjusts the TD sensor control voltage (Vtcnt) in order to adjust the TD sensor output voltage (Vt) to target value ± 0.2V. Adjustment flow: 1. Developer presence detection 2. Developer not detected. OK: Proceeds to Vtcnt adjustment. NG: SC336-0X 3. TD sensor calibration (Fluctuate Vtcnt and measure Vt) 4. TD sensor calibration result judgment OK: TD sensor calibration succeeded. NG: SC360-0X
• Causes: • TD sensor defective • Loose connection • Harness broken • Developer is not new
• Remedy: • Replace the TD sensor. • Replace the development unit.

• Code: SC360-02
