• Code: 0030
• Description: FAX PWB system error The FAX process cannot be continued due to the malfunction of the FAX PWB.
• Remedy: FAX PWB: 1. Unplug the power cord from the wall outlet, and reinstall the FAX PWB, and then plug in the power cord and turn the power on. 2. Reinstall the FAX firmware. 3. Replace the FAX PWB.

• Code: 0070
• Description: FAX PWB incompatible detection error In the initial communication with the FAX PWB, any normal communication command is not transmitted.
• Remedy: FAX PWB: 1. Install the FAX system designed for the model. 2. Reinstall the FAX firmware.

• Code: 0100
• Description: Backup memory device error Outputs an abnormal status from the flash memory.
• Remedy: Flash memory (Main PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Check that the connectors on the main PWB are properly connected, and if not, re-connect them. 3. Replace the main PWB.

• Code: 0120
• Description: MAC address data error In case MAC address is invalid data
• Remedy: Flash memory (Main PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Check the MAC address on the network status page. 3. If it is blank, obtain an EEPROM with its MAC address written by the service support and install it. 4. Replace the main PWB.

• Code: 0130
• Description: Backup memory Read/write error (main PWB) Read/write to the NAND memory cannot be executed.
• Remedy: Flash memory (Main PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Check that the connectors on the main PWB are properly connected, and if not, re-connect them. 3. Replace the main PWB.

• Code: 0140
• Description: Backup memory data error (Main PWB) At power up, the data that was read from the NAND memory has been determined to be a error.
• Remedy: Flash memory (Main PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Execute U021 initialize memory. 3. Replace the main PWB.

• Code: 0150
• Description: EEPROM read/ write error (Engine PWB) No response is issued from the device in reading/ writing for 5 ms or more and this problem is repeated 5 times successively. Mismatch of reading data from two locations occurs 8 times successively. Mismatch between writing data and reading data occurs 8 times successively.
• Remedy: EEPROM (Engine PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Check that the EEPROM is properly installed on the engine PWB and if not, reinstall it. 3. Replace the engine PWB. 4. Check the EEPROM and if it is damaged, contact the service support.

• Code: 0160
• Description: EEPROM data error (Engine PWB) Reading data from EEPROM is detected abnormal.
• Remedy: EEPROM (Engine PWB): 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Execute U021 initialize memory. 3. If the EEPROM data is corrupted, contact the service support.
