Description: P/H Module Logic Fault. A fatal error was detected in the Tray Module.
Remedy: 1. Turn the power Off and On. 2. Turn the power Off and check the connection between the MD PWB P/J542 and the Tray Module PWB P/J541 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • Tray Module PWB • MD PWB • MCU PWB
Code: 377.320
Description: All Feed Tray Broken. All the Feed Trays that are connected to the IOT were detected to have malfunctioned.
Remedy: Enter dc122 Fault History. Go to the RAP of the affected Paper Tray.
Code: 377.602
Description: Transparency Sensor Fault. An abnormal value was detected from the Transparency Sensor. (This is a hidden failure. Data is only recorded in history.)
Remedy: Check the following: • The Transparency Sensor and Reflective Prism for contamination and improper installation • Use of Transparency out of spec (refer to the Media and Tray Specifications). • The Transparency Sensor for failure: dc140 Analog Monitor [077-200] (PL 15.2) • The connection between the Transparency Sensor P/J161 and the MD PWB P/J523 for open circuit, short circuit, and poor contact • The connector ( P/J452) between the MD PWB and the MCU PWB for poor connection If no problems are found, replace the following parts in sequence: • MD PWB • MCU PWB
Code: 377.900
Description: Reg Sensor Static Jam. 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 Reg Sensor detected paper.
Remedy: Check the following: • The Reg Sensor for remaining paper, contamination, Actuator return failure, or improper installation • The Reg Sensor for failure: dc330 Component Control [077-103] (PL 15.2) • The connection between the Reg Sensor P/J160 and the MD PWB P/J523 for short circuit If no problems are found, replace the following parts in sequence: • MD PWB • MCU PWB
Code: 377.901
Description: Exit Sensor 1 Static Jam. 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 Fuser Exit Sensor detected paper.
Remedy: Check the following: • The Fuser Exit Sensor for remaining paper, contamination, Actuator return failure, or improper installation • The Fuser Exit Sensor for failure: dc330 Component Control [077-101] (PL 7.1) • The connection between the Fuser Assembly DJ600 and the MCU PWB P/J431 for short circuit If no problems are found, replace the MCU PWB.
Code: 377.902
Description: Exit Sensor 2 Static Jam. 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 Exit 2 Sensor detected paper.
Remedy: Check the following: • The Exit 2 Sensor for remaining paper, contamination, Actuator return failure, or improper installation • The Exit 2 Sensor for failure: dc330 Component Control [077-100] (PL 17.4) • The connection between the Exit 2 Sensor P/J164 and the MD PWB P/J522 for short circuit • The L/H High Cover Assembly for damage or mismatch If no problems are found, replace the following parts in sequence: • MD PWB • MCU PWB
