Ya, they need to update there "how to section" very badly.
I found out that you remove the tape around the hole and then install in your printer. Cartridges did not work unless yellow tape was removed in my printer. Also, be careful not to spill the ink :-)
BTW; My Photo Black cartridge leaked until I re-aligned the heads. After the heads were re-aligned, my R2400 works like a champ, colors look great, and I'm very happy. I now can print without the ink costing me a large fortune :-)
