Everyone already knows buying off-brand ink refill cartridges saves money, but you’re still paying more than oil, blood or petrol. Cool Tools suggests one possible solution: buy ink in bulk, and hook it up to a continuously refilled system.

These continuous ink systems hold a large quantity of ink, and modifies the way it feeds into your printer, which has a side effect of voiding your warranty. You can gather the parts and modify your printer yourself, but Cool Tools recommends Cobra Ink, a company that does the modification for you for $US50-$US100 over printer’s RRP. The upside to doing it this way is that Cobra Ink supplies their own warranty, since Epson or HP’s is voided by your mod.

If you do a lot of colour printing, this seems like a good moneysaver. If you’re like me and only print black and white, with a little bit of colour occasionally, a laser printer might be better, since that doesn’t have the drying out problem.

  • I’ve been using a RHIAC system for years and it’s been awesome.

    As someone who has moved house a lot, be mindful that they do not respond well to being moved as they operate on an air tight system that is impacted if the reservoir is lifted higher than the printer.



  • My wife is a teacher and prints a lot of stuff, we were going through $100+ of ink per month on our HP c5380, bought a rihac system – just brilliant – getting ready to buy first refill.

  • Rihac doesnt modify the printer. You use special ink cartridges.
    If push came to shove, I think you’d find that the printer manufacturer would have a hard time invalidating the warrantee based on using these. They would have to prove it had damaged the printer, rather than just issue a generic statement.
    You do have rights as a consumer.

    BTW, the Rihac system is great. Very cost effective, pretty easy to setup, and the inks are good quality. I use my canon printer for photography prints, so I’m pretty critical of the results.

  • I tried one of these a few years back on a Canon… it sort of worked, but to be honest, it ended up been more effort than it was worth, and over time stopped working (hence the “sort of” worked.) Ended up just refilling normal cartridges with the ink left over.

  • +2 for rihac. Had a crappy system from hong kong which never did work but saw the rihac guys at a shopping centre display and they convinced me to give their system a go and to be honest i love it. good to see they are popular cause they seem to know what their on about.
