• Code: 124-315, 124-317
• Description: Speed mismatch or Product Model Identification data error has occurred due to one of the following problems. • At least one of the IOT Speed that is stored in 3 locations is different. • At least one of the Product a/f Model identification data that is stored in the 3 locations is different. • 124-315: At least one of the IOT productivity switch data was at the 3 locations is different. All IOT speed mismatch. (Contents corrupted. The PWB was replaced.) • 124-317: At least one of the Product a/f Model at the 3 locations is different. All Product Model mismatch. (Contents corrupted. The PWB was replaced.)
• Causes: • MCU PWB, PL 12.1.15 • Image Processor PWB, PL 12.4.1
• Remedy: 1. Perform DC131 NVM Read/ Write. 2. Compare the following 3 values: • DC131 [700-600] • DC131 [700-601] • DC131 [700-602] 3. Compare the 3 data. If all 3 are different, replace the MCU PWB. 4. If the problem persists, replace the I/P PWB PWB). 5. If 2 among the 3 are matched, perform DC132 Machine Serial Number Settings to match all 3 values.

• Code: 124-316, 124-318
• Description: Product a/f Model identification data or Product Type for SW Key error has occurred due to one of the following problems. • Although the Product a/f Model identification data that is stored in the 3 locations are matched, their values are not set (0). • Although the Product Type For SWKey that is stored in the 3 locations are matched, their values are not set (0). • 124-316: The Product a/f Model was not set at all 3 locations. Product Model fails. (Contents corrupted. The PWB was replaced.) • 124-318: The Product Type For SWKey was not set at all 3 locations. Product Type For SWKey fails. (Contents corrupted. The PWB was replaced.)
• Causes: • MCU PWB, PL 12.1.15 • Image Processor PWB, PL 12.4.1
• Remedy: 1. Replace the MCU PWB. 2. If the problem persists, replace the I/P PWB PWB).

• Code: 124-319
• Description: At least one of the Product Type For SWKey that is stored in 3 locations is different. • 124-319: At least one of the Product Type for SWKey at the 3 locations is different. All Product Type for SWKey Mismatch. (Contents corrupted. The PWB was replaced.)
• Causes:
• Remedy: 1. Perform DC131 NVM Read/ Write. 2. Compare the following 3 values: • DC131 [700-606] • DC131 [700-607] • DC131 [700-608] 3. Compare the 3 data. If all 3 are different, replace the MCU PWB. 4. If the problem persists, replace the I/P PWB PWB). 5. If 2 among the 3 are matched, perform DC132 Machine Serial Number Settings to match all 3 values.

• Code: 124-320
• Description: SEEPROM Fail Write error has occurred in the SEEPROM on the I/P PWB.
• Causes: • EEPROM PWB, PL 12.1.18 • Image Processor PWB, PL 12.4.1
• Remedy: 1. Reinstall the EEPROM. 2. If the problem persists, replace the I/P PWB PWB).

• Code: 124-321
• Description: Backup SRAM Fail Write error has occurred in the NVM on the I/P PWB.
• Causes: • Image Processor PWB, PL 12.4.1 • 1 GB DDR2 DIMM, PL 12.4.2
• Remedy: 1. Reinstall the NVRAM). 2. If the problem persists, replace the I/P PWB PWB).

• Code: 124-324
• Description: All Billings Mismatch The Billing Counters that are stored in multiple locations are all different.
• Causes: • MCU PWB, PL 12.1.15 • Image Processor PWB, PL 12.4.1
• Remedy: 1. Replace the MCU PWB. 2. If the problem persists, replace the I/P PWB PWB).

• Code: 124-325
• Description: Billing Restoration Fail At least one Billing Counter is not matched and correction is not possible.
• Causes: • MCU PWB, PL 12.1.15 • Image Processor PWB, PL 12.4.1
• Remedy: 1. Perform DC132 Machine Serial Number Settings. 2. Compare the 3 Serial Number. If all 3 are different, replace the MCU PWB. 3. If the problem persists, replace the I/P PWB PWB). 4. If 2 among the 3 are matched, replace the PWB that has the different value.

• Code: 124-326
• Description: IOT Speed Not Registered At boot, the status of speed registration procedure for IOT was detected to be 1 or 2.
• Causes:
• Remedy: 1. This failure will start the IOT speed change procedure and the user should follow the dialog that is displayed on the UI to enter the SW Key for IOT speed change.
