Code: E677-0001
Description: DPRAM size error In communication for initialization, the DPRAM size returned by the PDL board to the host machine has an error. (The host machine is aware of the DPRAM size in advance; the DPRAM is a dual-port RAM used for communication between the host machine and the PDL board, and is mounted on the PDL board.)
Causes: The connection between the host machine and the PDL board is faulty. The system software is faulty. The hard disk is faulty. The PDL board is faulty. The system controller PCB of the host machine is faulty.

Code: E677-0002
Description: Initialization communication error In communication for initialization, the contents of communication returned by the PDL board to the host machine have an error and, therefore, communication cannot be established.
Causes: The connection between the host machine and the PDL board is faulty. The system software is faulty. The hard disk is faulty. The PDL board is faulty. The system controller PCB of the host machine is faulty.

Code: E677-0004
Description: PDL board disconnection After the connection of the PDL board is recognized at power-on, the PDL board is disconnected. During power-up, monitoring is executed at intervals of 2 min; however, if the CPU is not on (sleep state or the like), no error will be identified even if the PDL board is discontented. If the PDL board is disconnected in sleep state, the absence of the PDL board will be recognized at the start of the CPU.
Causes: The connection between the host machine and the PDL board is faulty. The system software is faulty. The hard disk is faulty. The PDL board is faulty. The system controller PCB of the host machine is faulty.
