OfficeJet Pro 8730 does not accept password

[treberta]

It set an administrator password for my printer. The machine accepted it („enter password“ and „confirm password“), but if I try to log in to the ews with those credentials, they don‘t work.

So now every single setting both in the ews and the printer‘s display is locked know. I can‘t even restore factory settings. Please help!

Problem solved. I use a password generator that ist set to create 18 character password. That's what I used, that's what I copied into the fields in the EWS. It showed no sign that it only uses the first 16 characters! So by reducing the password length one by one, I could unlock the EWS.

Maybe that will help some people that face the same problem.
