I'm going to do something some of my peeps my consider "geeky". Tired of running out of ink for my Epson Stylus Photo R1900, I bought a CIS system. I just ran out of one cartridge of ink and instead of replacing that one, I'm going to replace them all. And if all goes well, all I'll need to do in the future is squeeze ink into the container. More efficient and less waste that way (I've got a box full of empty cartridges).
I'm kind of nervous about this. I have to break out the lid of the old cartridge system and I'm not looking forward to that at all.
Here's a video link for an idea of what I have to do.
