Unable to resolve problem with new printer

I have bought 2 laptops, 6 desktops, and numerous other items from Dell without a problem. The last purchase was for a laptop and I got talked into adding a printer which was fine mine was on the way out. I recieved the printer and followed the idiot guide on how to install the printer. The process went well until I put the ink cartridges into the printer. All I get is a message ringing no cartridges detected. I wwent through the troubleshooting on the site, then went through it again with a Dell tech. The tech sent me a new printer head which I'm not sure I'm qualified to change or if it ruins my warranty but I tried to change it anyway. I started step 1 which was to hit the home key and proceed to settings. Hit home key warning screen still present, hit cancel home screen comes up, hit settings and warning screen back. I then sent back an email explaining the problem and my discomfort in performing surgery on my "new" printer. I just want to send in this defective printer and get one that works. I have stumbled around the website, been disconnected on the phone, and told we have bad reception and still have a giant paper weight in my office. This first request was on 10/18/2012 and the first of December is uopn us.
