But installing this gear can get really messy and hairy. You are on your own if it does not work correctly. And some printer models are easier to retrofit than others. I opted for a more elegant and not that much more expensive option: have the pros do it. Cobra Systems will install their continuous ink supply system on twelve different brand new Epson printer models. For about $50-100 more than the cost of the new printer, they will ship you a ready-to-use modified new printer with refillable ink containers already installed. Because this modification voids Epson’s warranty, they provide their own warranty. They guarantee it will work. Period. In fact, in my experience Cobra’s service is amazing. They will make absolutely sure your system is working to your satisfaction no matter what, even if they have swap it out at their cost. (via Cool Tools: Cobra Ink System)
