Press the Stop button. Turn ON Component Control [072-102] (Tray 2 Level Sensor). Use a sheet of paper, etc. to block/clear the light path to the Tray 1 Level Sensor. Does the display change between High/Low? Y↓N→Use OF 99-2 RAP to check the Tray 2 Level Sensor (PL 9.6). Press the Stop button and turn the power OFF. Reload the machine software (GP 16). Check the Tray Lift Gear for damage or the Tray Lift mechanism for mechanical load. If no problems are found, replace the MCU PWB (PL 18.2).

• Code: 072-212
• Description: Tray 2 Paper Size Sensor Broken RAP Abnormal output AD value from Tray 2 Size Sensor was detected.
• Remedy: Check the following: • Broken link and breakage at the bottom of the tray • The Actuator at the rear of the Tray for operation failure • The Tray 2 Paper Size Switch for failure: Analog Monitor [072-200];Component Control [072-104] (PL 9.1) • The connection between the Tray 2 Paper Size Sensor P/J123 and the MCU PWB P/ J414 for open circuit, short circuit, and poor contact Reload the machine software (GP 16). If no problems are found, replace the MCU PWB (PL 18.2).

• Code: 072-900
• Description: Tray 2 Feed Out Sensor Static Jam RAP When the power was turned ON, the M/C was stopped (Cycle Down/ Shut Down), or when the interlocks were closed (all interlocks including options), the Tray 2 Feed Out Sensor detected paper.
• Remedy: Check the following: • The Feed Out Sensor (PL 15.1) for remaining paper, contamination, Actuator return failure, or improper installation • The Feed Out Sensor for failure: Component Control [072-100] (PL 15.1) • The connection between the Feed Out Sensor P/J110-1 and the MCU PWB P/J410-B3 for short circuit Reload the machine software (GP 16). If no problems are found, replace the MCU PWB (PL 18.2).

• Code: 073-101
• Description: Tray 3 Misfeed RAP The Tray 3 Feed Out Sensor does not turn ON within the specified time after the Feed from Tray 3 has started.
• Remedy: Remove Tray 3. Turn the power ON and enter the Diag mode. Turn ON Component Control [073-001] (Tray 3 Feed/Lift Motor). Does the Tray 3 Feed/Lift Motor rotate? Y↓N→Go to the +24VDC-2 IOT wirenets. Is the voltage between the Tray Module PWB P/J 541-8 (+) and the GND (-) +24VDC? Y↓N→Go to +24VDC Power RAP. Turn the power OFF, then measure the Tray 3 Feed/Lift Motor wire wound resistance. Check the resistance of the following. • Between the Tray Module PWB P/J555 -1 and P/J555-2 • Between the Tray Module PWB P/J555-3 and P/J555-4 Is the resistance approx. 4Ohm for each? (When the temperature is 25 °C) Y↓N→Check the connection between the Tray Module PWB P/J555 and the Tray 3 Feed/ Lift Motor P/J222 for open circuit, short circuit, and poor contact. If there are no problems, replace the Tray 3 Feed/Lift Motor (PL 11.9). Measure the resistance between the Tray Module PWB P/J555-1/2/3/4 and the Frame. Is the resistance infinite for all? Y↓N→Check the wires of the pins with non-infinite resistance for peeled-off coatings and short circuits due to pinching. Replace the following parts in sequence: • Tray Module PWB (PL 11.13) • MCU PWB (PL 18.2) • Press the Stop button. Turn ON Component Control [077-033] (TM Takeaway Motor).

• Code: 073-105
