I have used my h Document Center 430ST to network scan and print for years. All of a sudden it stopped scanning and e-mailing. I discovered that many of the settings had been scrambled for some reason and when I put them right things seemed to work fine again. One problem remains. Whenever I try to scan it asks for a password. For the lack of something better, I enter "admin" and it then works. Any idea where in the browser interface I can fix this issue? Thanks
