• Code: E196-4045
• Description: Engine EEPROM write error An EEPROM read/write failure has been detected in the engine portion of the firmware.
• Remedy: 1. Start in download mode to upgrade the firmware. 2. Restart the printer in service mode to clear the error. 3. Replace the main controller PCB.

• Code: E196-404C
• Description: Serial number information mismatch A mismatch has been detected between the serial number information stored in the EEPROM on the main controller PCB and that stored in the EEPROM on the MTC relay PCB at startup.
• Remedy: 1. Check to see if the correct PCB is mounted, since a PCB of the wrong model may have been mistakenly mounted during servicing. 2. Invoke service mode to implement PCB replacement.

• Code: E196-404D
• Description: Machine ID information mismatch A mismatch has been detected between the model ID information stored in the EEPROM on the main controller PCB and that stored in the EEPROM on the MTC relay PCB at startup.
• Remedy: 1. Check to see if the correct PCB is mounted, since a PCB of the wrong model may have been mistakenly mounted during servicing. 2. Invoke service mode to implement PCB replacement.

• Code: E196-404E
• Description: An EEPROM read/ write error has been detected in the controller portion of the firmware.
• Remedy: 1. Start in download mode to upgrade the firmware. 2. Start in service mode to clear the error. 3. Replace the main controller PCB.

• Code: E198-401C
• Description: Faulty RTC Any error other than the two errors mentioned below has been detected while initializing the RTC at startup.
• Remedy: 1. Restart the printer in service mode. 2. Replace the main controller PCB.

• Code: E198-401D
• Description: RTC low battery error A battery error has been detected while initializing the RTC at startup.
• Remedy: 1. Restart the printer in service mode. 2. Check the RTC battery. 3. Replace the main controller PCB.

• Code: E198-401E
• Description: RTC clock stop The RTC has been detected idle while initializing the RTC at startup.
• Remedy: 1. Restart the printer in service mode. 2. Replace the main controller PCB.

• Code: E199-404B
• Description: Temperature/humidity sensor error When temperature 0 and humidity 0% are detected, the detection mechanism is considered failed and an error message is displayed.
• Remedy: 1. Restart the printer in service mode to clear the error. 2. Identify the firmware version and update the firmware to the last release if it is earlier than Ver.1.31 (firmware defect). 3. Remove and reinsert the temperature/humidity sensor PCB connector 4. Replace the temperature/humidity sensor PCB.
