I wasn't sure about buying non epsom cartridges as I had a bad experience with them just not working and didn't want to throw anymore money away. But I also begrudge paying epsom prices, so thought I would take a chance with the ink factory and to my pleasant surprise they worked perfectly. Just a heads up message on the printer telling me that cartridges weren't genuine epsom, press ok and jobs a goodun. Thankyou very much ink factory!
