HP OfficeJet 8720 internal system error

[beaujo007]

I apologize for not answering for a quite long time. (HP OfficeJet 8720 internal system error)

It took some time to come back, and to find out that something is not working as expected.

- Factory Reset by the special procedure (semi-full reset) did not reset ALL values. So most of the private information are kept in the printer. Well, it is e semi-full reset.

- The problem resist: Internal System Error when I try to connect to "Network -> Advanced Settings -> Management Protocol"

How can I do a FULL reset?

Any hints on the error message?
