• Code: 116-323
• Description: Controller NVM Data Defect Any of the following was detected: • The On Board NVM data of the Controller is corrupted. • The On Board NVM of the Controller is not installed. • Any one of the Print Counter has reached its maximum value. • The number of times the NVM can be changed has reached its limit. NOTE: If this Fault reoccurs after performing Data Backup/Restore, perform Data Restore again. (Perform NVM Matching (NVM [621-400]) in the CE Mode.)
• Remedy: 1. Turn the power OFF and ON. 2. Perform NVM Initialize in the CE Mode. (Refer to 6.5.2.4 NVM Initialize)

• Code: 116-324
• Description: Exception Fail The CPU has rebooted due to the occurrence of an exception.
• Remedy: Upgrade the Controller software or contact the Support Department.

• Code: 116-334
• Description: NVM Data Mismatch The verification result between the On Board NVM and the Backup NVM of the Controller is mismatched. (This includes cases where one of the NVM is Blank)
• Remedy: 1. Turn the power OFF and ON. 2. Perform NVM Matching (NVM [621-400]) in the CE Mode.

• Code: 116-377
• Description: IIT Interrupt Timeout The DMA start trigger when scanning documents cannot be detected for a specified time.
• Remedy: 1. Turn the power OFF and ON. 2. Turn OFF the power and check the Flat Cable between the IIT Carriage J700 and the ESS/MCU PWB J420 for open circuits, short circuits, and poor contacts (especially, check whether the Flat Cable was inserted in a skewed manner). 3. Check the ESS/MCU PWB for improper installation (loose screw). 4. Upgrade the Controller Firmware. ADJ 18.2.3 5. If no problem is found, replace the ESS/MCU PWB (PL 18.3).
