• Code: E196-4042
• Description: Flash write error Failed to write flash ROM on execution of the firmware update.
• 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: E196-4043
• Description: Firmware update failure error Failed to allocate a work area on RAM on firmware update.
• 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: E196-4044
• Description: EEPROM size error Size information about the firmware data transmitted on firmware update and the size of actually transmitted data do not match.
• Remedy: 1. Start in download mode to upgrade the firmware. 2. Restart the printer in service mode to clear the error. 3. Check the firmware transfer environment (IF changes, PC). 4. Replace the main controller PCB.

• 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.
