I had an employee who tried one of those. She couldn't figure it out so she brought it to me and I did it for her. It wasn't real complicated and it worked. Just seems a bit more than I want to put up with.
Look into recycled cartridges. Usually you can buy them already refilled for half price.
I had good results with the kits. Saves me over twenty bucks a cartridge. If you're careful then it isn't messy, but I would still invest in some latex gloves.
Thanks for all the replys..and the link. I just bought a neato 4 in one office machine and I have been faxing out resumes and stuff all day. Ink for it is expensive and since im not making too much money, i figure it would be best to save as much money as possible.
