Purchased yesterday, 11/29. The ink ran out, so I bought three colors. I only installed them; I haven't printed anything. The empty space in the ink tank might make you think there's no ink (I was surprised when I first saw it too), but this is normal for a new cartridge. I bought it yesterday and installed it at home, but it didn't detect the ink. I went to the electronics store and they said it needed repair. I'm in the middle of urgently making mourning postcards, so I couldn't wait for the repair period and decided to buy a new printer. Therefore, the ink is still new, so I'm putting it up for sale.
