The life counter on the PF motor is full. When Mutoh designed and tested these printers they averaged out the life expectancy of the motors, pumps and print head. Your PF motor is at that point. It doesn't mean that it is bad or that it needs to be replaced. It could work another 5 years or it could fail tomorrow.
You will have to reset this log, if you give me a call I can walk you through the steps.
