Troubleshooting Procedure
Step Actions and Questions
1. Perform DC131 NVM Read/ Write on page 2-45.
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 (REP 12.4 MCU PWB on page 4-206).
4. If the problem persists, replace the I/P PWB (REP 12.17 Image Processor (I/P) PWB on page 4-228).
5. If 2 among the 3 are matched, perform DC132 Machine Serial Number Settings on page 2-47 to
match all 3 values.
