This video shows the JR ink Continuous Ink Supply System installed on my Canon MX310. Unlike some other CISS systems for other printers, this one requires a bit of DIY assembly using the supplied drill tool to make port holes into your own cartridges. Initially, I had some problems getting the ink to flow into the cartridges - but fixed this with a new set of compatible cartridges from TESCO. Annoyingly, the ink monitor needs resetting when the printer thinks the cartridge is empty.
