• Code: 372
• Description: TD sensor adjustment error: K. SC is issued only if one of followings is satisfied. • During TD sensor initialization, the output value of the black, magenta, cyan, or yellow TD sensor is not within the range of the specified value with SP3238-001 to -004 (default: 2.5V) ± 0.2V. • The TD sensor output is 0.7 V or more when the Vcnt is 4.3 v. • The adjusted Vcnt is 4.7 V or less.
• Causes: • Heat seal not removed from a new developer pack • TD harness sensor disconnected, loose or defective • TD sensor defective • Harness between TD sensor and drawer disconnected, defective • Different developer density from initial developer density
• Remedy: 1. Remove the heat seal from each PCDU. 2. Replace the PCDU.

• Code: 373
