I have a Xerox 550 with a 010-321 fault that will not clear. I POPO'd I tried new fuser, check for paper and debris in plug everything there looks good. I changed to a new fuser drive motor with no help. reset connector J405 on MCU The next step is MCU pwb. I was wanting to know if there is a NVM value location that needs resetting. If anyone has any ideas I am open to your suggestion. Edoc does not say there is an NVM value to reset but I thought I would ask for other ideas. Thanks

Check the following:

• Fusing Unit Nip Sensor: DC330 [010-203] (PL 7.3)
• The Sensor Actuator for damage. (PL 7.3)
• The Retract Mechanism for wear and damage.
• The One Way Clutch for skidding.
• The Drawer Connector ( DP/DJ612) for poor contact.

If no problems are found, replace the MCU PWB. (PL 18.2)
