I start the installation process and the software tells me that the printer is going to restart. the printer restarts and nothing appears to happen. After a while the printer's head start moving as if going through a restart progress. After I see that I try the run the Activation software and it shows up as USB001 (XP-6000 series). After I enter the code emailed to me it tells me that the software could communicate with the printer and that's it. I'm 100 percent sure that the code emailed to me is incorrect or non-functioning. I've never had a problem with chipless firmware. I've bought keys from a another website for other printers and those worked fine. I'm getting tired of this and I would like a refund or at the very least a partial refund. If that's impossible I would like another key that actually works with my printer. I'm sure you have a way to see the key that was sent to me was not used in any capacity. Thank you....
