• Code: 0100
• Description: Backup memory device error Outputs an abnormal status from the flash memory.
• Remedy: Flash memory (Main/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 connectors on the main/engine PWB are properly connected, and if not, re-connect them. 3. Replace the main/engine PWB.

• Code: 0120
• Description: MAC address data error In case MAC address is invalid data
• Remedy: Flash memory (Main/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 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/engine PWB.

• Code: 0130
• Description: Backup memory Read/write error (Main/ Engine PWB) Read/write to the NAND memory cannot be executed.
• Remedy: Flash memory (Main/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 connectors on the main/engine PWB are properly connected, and if not, re-connect them. 3. Replace the main/engine PWB.

• Code: 0140
• Description: Backup memory data error (Main/Engine PWB) At power up, the data that was read from the NAND memory has been determined to be a error.
• Remedy: Flash memory (Main/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. Replace the main/engine PWB.

• Code: 0150
• Description: EEPROM read/ write error (Main/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 (Main/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 main/ engine PWB and if not, reinstall it. 3. Replace the main/engine PWB. 4. Check the EEPROM and if it is damaged, contact the service support.

• Code: 0160
• Description: EEPROM data error (Main/Engine PWB) Reading data from EEPROM is detected abnormal.
• Remedy: EEPROM (Main/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. If the EEPROM data is corrupted, contact the service support.

• Code: 0170
• Description: Billing counting error Mismatch between the value of the main/engine PWB and EEPROM, in one of the value of billing counter, life counter, or scanner counter.
• Remedy: EEPROM (Main/Engine PWB) 1. Check that the EEPROM installed in the main/ engine PWB is correct and, if not, install the correct EEPROM for the model. 2. Replace the main/engine PWB. 3. If the EEPROM data is corrupted, contact the service support.

• Code: 0190
• Description: Backup memory device error (engine) Unable to read out data from the IC on the main unit PWB. Read out data from the IC on the main unit PWB. (3 retrials)
• Remedy: EEPROM (Main/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 connectors on the main/engine PWB are properly connected, and if not, re-connect them. 3. Contact service headquarters to get an EEPROM to install.
