Thank you for the reply. Though copying from the how to update the firmware on your printer page does not help me.
Installed new firmware (everything installes without errors), after pressing continue the message and/or restarting "wrong disk installed" is showing. This is because th previous disk was encrypted and locked to the printersystem. And there lies my problem. The newly inserted disk cannot be locked to the printersystem. The messages 99.09. 62-63-66 has all been showing and been fixed. Now its only the lock to printer function left.
Hps "hlep" pages show the message lock the disk to the printer, as it was a normal thing to do... Well my system prohibites me from doing so, even after clearing the password for the system and cleaning the disk.
So thanks for the help, but no solution.
Any other suggestions?
