• Remedy:

• Code: 4049
• Display: Unknown file. Check file format. Turn off printer, wait a while, then turn it on again.
• Description: Wrong transfer ROM data model Files for a different model have been transferred on firmware update.
• Remedy: 1. Restart the printer in service mode to clear the error (this error won't occur when FUT is used). 2. Start in download mode to upgrade the firmware. 3. Replace the main controller PCB.

• Code: 404A
• Display: ERROR E194-404A Call for service.
• Description: Non-ejection count error A non-ejection part operation counter has reached a specified limit.
• Remedy: Check the parts counter and replace the target unit or Refresh Service Kit. Initialize the parts counter for the target unit after the replacement.

• Code: 404B
• Display: ERROR E199-404B Call for service.
• 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.

• Code: 404C
• Display: ERROR E196-404C Call for service.
• 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: 404D
• Display: ERROR E196-404D Call for service.
• 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: 404E
• Display: ERROR E196-404E Call for service.
• 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: 404F
• Display: ERROR E144-404F Call for service.
• Description: Pump revolutions full The number of HP pre-ejection pump revolution has reached the defined value.
