Refill ink tank

The ink tank got empty, so I refilled it.

The way of refilling was different from the Japanese which I was used to. Putting the new ink on the bottom of ink tank. However it was OK until refill, I can't print for some reasons. The bad things is that my printer doesn't recognize the tank even though I put it back. I wanna print my music and document. Got me stumped.

I wonder if I should buy a new tank. Hmm.
