• Code: 092-310
• Description: CTD Sensor Error/CTD Sensor/Check Unit
• Causes: • Left Side Harness, PL3.1.18 • MCU Board, PL8.2.13 • Transfer Unit, PL6.1.7
• Remedy: 1 Check the ADC Sensor Window Open the Front Cover. Is the ADC Sensor window dirty? Go to step 2. Go to step 3. 2 1. Turn off the power, and gently wipe the ADC Sensor window with a clean dry cloth or cotton swab. 2. After wiping the window, close the Front Cover. Does the error still occur when the power is turned OFF and ON? Go to step 3. Complete. 3 Check the Transfer Unit belt. Open the Front Cover. Is there any damage on the belt surface? Replace the Transfer Unit. Go to step 4. 4 Check the connections between the MCU Board and Transfer Unit. Are both P/J28 and P/J281 connected correctly? Go to step 6. Reconnect P/ J28 and/or P/ J281 correctly, then go to step 5. 5 Does the error still occur when the power is turned OFF and ON? Go to step 6. Complete 6 Check the Left Side Harness for continuity 1. Disconnect J281 from the Transfer Unit. 2. Disconnect J28 from the MCU Board. Is each cable of J281 <=> J28 continuous? Go to step 7. Replace the Feeder Assy or Left Side Harness Assy. 7 Check the power to the ADC Sensor 1. Disconnect J28 from the MCU Board. 2. Measure the voltage between P28-1 and ground. Does the voltage measure about +5 VDC? Replace the Transfer Unit Replace the MCU Board

• Code: 092-661
• Description: Env Sensor Error Humidity sensor error is detected.
• Causes: • Humidity Sensor, PL8.2.7 • MCU Board, PL8.2.13
• Remedy: 1 Reseat the connector (P/J201) on the Humidity Sensor. Does the error still occur when the power is turned OFF and ON? Go to step 2. Complete 2 Check the power to Humidity Sensor. 1. Disconnect the connector of J20 from the MCU Board. 2. Measure the voltage across P20-4 <=> ground on the MCU Board Is the voltage about +5 VDC? Replace the Humidity Sensor. Replace the MCU Board.

• Code: 094-330
• Description: DTB Life Over/Transfer Life
• Causes: • MCU Board, PL8.2.13 • Transfer Unit, PL6.1.7
• Remedy: 1 Check the life counter value of the Transfer Belt: Service Mode > Parameter > Life DTB Waste. Is the life count value near the maximum? Replace the Transfer Unit. Replace the MCU Board.
