Hp will not recognize my serial number

[aloec]

I am trying to register my HP 3700 Deskjet printer. I have the serial number, but every time I enter it on the HP website to register it for a warranty, I am told that the serial number is not recognized. I am certain that I am typing in the given number correctly. I am unable to go through support directly or call a support member because I don't have a registered product. So I have been going around in circles. This is very frustrating.

Keep in mind that HP serial numbers typically do not have alphabetic "O" in them, they are usually zeros. I have also escalated your post and have asked to moderator to have an HP agent reach out to you. They will normally contact you via a private message. The envelope icon in the upper right will turn red when you have a message waiting.
