Mobile Printing & Cloud Printing

I recently sold my 3830 to a friend of mine and told her she could run the rest of my Instant Ink Cartridges out before she had to either buy more ink or sign up for HP's Instant Ink program on her own. The cartridges are getting low and she's opted to join HP's program. The problem we're having is with the enrollment instructions. It directs you to print out a "Claim Code" in order to join the program but when I print out the document there is no "Claim Code" to use which stops us dead in our tracks during the enrollment process (as there is no option to skip this step). I'm assuming the code isn't there because the printer is already registered with the program and the "Claim Code" is for "out of the box" customers attempting to enroll in the program for the first time.

So can anyone advise us on how to get around this issue? The printer is currently registered to me and I've been paying the monthly fees since November. We want to completely remove my name from the printer software, cancel my Instant Ink subscription, re-register the printer under her name, and sign her up for the Instant Ink program (or at least give her the option to do so if that's what she ultimately decides). Either way, I need to get my name removed from her printer so we can put a period on this.

Any advice would be greatly appreciated.
