Today I received my ink cartridges, as some of the old cartridge (original) are still more than half full, I did not want to just throw away this .. the black cartridge was as good as empty and so I changed it. So ... the ink indicator pointed at once to the cartridges all are empty or they were not properly inserted. Remedy was turn the printer off for a few minutes, turn it back on and already showed the ink level Properly (the new black full) My printer is an Epson XP 205 I have already printed out a couple of pages and notice no difference from before, sometimes Prints I also pictures from, about, I can not say anything yet, but I guess it will work this well! :) 'M Curious how long I come with the ink supply ... the original hold no eternity! Conclusion: you can buy, at first maybe a little fumbling according as which printer you have!
