If you have managed to find the special keystrokes online which are meant to enter a menu which allows input of a regionalization reset code...Don't make any entries in the regionalization reset menu without an HP Support agent on the phone with you!
If you input three wrong entries with out a code specifically supplied by an HP Support team member, your printer may never print again. The codes also cannot be reused!
