2	Checking the wire	The wire is improperly connected or faulty.	Reconnect or replace the wire between the DP opening/ closing sensor and the DP main PWB.
3	Checking the DP opening/ closing sensor signal	The DP opening/closing sensor signal output is faulty.	Check the output of the DP opening/closing sensor signal from the DP main PWB.
4	Replacing the DP main PWB	The DP main PWB is faulty.	Replace the DP main PWB.
5	Checking the wire	The wire is improperly connected or faulty.	Reconnect or replace the wire between the engine PWB and the DP main PWB.
6	Firmware upgrade	The firmware is faulty.	Upgrade the firmware to the latest version.
7	DP replacement	The document processor is faulty.	Replace the document processor.

2. F000: Communication error between the main unit and CPU

The panel cannot be detected since the CPU communication between the main PWB and the operation panel main PWB is unavailable.

Step	Check description	Assumed cause	Measures
1	Resetting the main power	The communication between the main PWB and the operation panel main PWB is faulty.	Turn the power switch and the main power switch off . After 5s passes, turn the main power switch and the power switch on.
2	Checking the wire	The wire is not properly connected.	Reconnect the wires between the main PWB and the operation panel main PWB. Then, fix or replace them if they are pinched by the other part or if they have any damage.
3	Executing U021	The backup RAM data is faulty.	Execute U021 to initialize the backup RAM data.
4	Checking the main PWB	The main PWB is faulty.	Reconnect the connectors on the main PWB. Then, fix or replace the wires if they are pinched by the other part or if they have any damage. When the issue is not resolved, replace the main PWB.
5	Replacing the operation panel main PWB	The operation panel main PWB is faulty.	Replace the panel main PWB.

3. F010: Program read error (SSD)

Step	Check description	Assumed cause	Measures
1	(When the service call error appears after replacing the SSD) Replacing the SSD along the correct procedures	The firmware is not stored in the SSD.	Insert the USB memory device containing all released firmware into the main unit, and turn the main power on.
2	Checking the SSD (if lit after replacing the SSD)	An SSD out of specification is installed.	Install the SSD matching the memory capacity specification.
3	Resetting the main power	The communication between the main PWB and the operation panel main PWB is faulty.	Turn the power switch and the main power switch off . After 5s passes, turn the main power switch and the power switch on.
4	Checking the wire	The wire is not properly connected.	Reconnect the wires between the main PWB and the operation panel main PWB. Then, fix or replace them if they are pinched by the other part or if they have any damage.
5	Executing U021	The backup RAM data is faulty.	Execute U021 to initialize the backup RAM data.
6	Checking the main PWB	The main PWB is faulty.	Reconnect the connectors on the main PWB. Then, fix or replace the wires if they are pinched by the other part or if they have any damage. When the issue is not resolved, replace the main PWB.

4. F020: System memory error (RAM reading/writing error or CPU memory error)

The error appears during the reading/writing check of the RAM for the CPU when the main unit starts up.

Step	Check description	Assumed cause	Measures
1	Resetting the main power	The communication between the main PWB and the operation panel main PWB is faulty.	Turn the power switch and the main power switch off . After 5s passes, turn the main power switch and the power switch on.
2	Executing U021	The backup RAM data is faulty.	Execute U021 to initialize the backup RAM data.
3	Checking the main PWB	The main PWB is faulty.	Reconnect the connectors on the main PWB. Then, fix or replace the wires if they are pinched by the other part or if they have any damage. When the issue is not resolved, replace the main PWB.
