Code: 024-920
Description: <IOT Standard Stacker Full> Center Tray Full is Detected.
Causes: • Full Stack Sensor (PL17.1.11) • Sensor Harness Assembly (PL17.1.23) • MCU Board (PL18.1.13)
Remedy: 1 Check the Full Stack Sensor operation Execute Digital Input diagnostic test 071-105, and check the Full Stack Sensor operation. Does it function normally? Replace the MCU Board. Go to step 2. 2 Check the Full Stack Sensor connection Check the connection between the Full Stack Sensor and the MCU Board. Are P/J154 and P/J15 connected securely? Go to step 3. Connect P/J154 and P/J15 securely. 3 Check the continuity between the Full Stack Sensor and the MCU Board Is each cable of P/J154<=>P/J15 continuous? Go to step 4. Replace the Sensor Harness Assembly. 4 Check the power to the Full Stack Sensor (+5 VDC) Check if the voltage between the MCU Board ground and the P/J15-4 pin is about +5 VDC. Replace the Full Stack Sensor. Refer to “+5 VDC Power FIP”.
