What is the EXACT model of your HP printer? Different printers often have different error messages/codes.
And please...follow the instructions you were given before asking the same question over and over and over and over and over again. If you don't like the answer, tough! In reality, people can't just wave a magic wand and make all your problems disappear, no matter how many times you post.
Follow the instructions you were given or don't bother posting.
