I just replaced several cartridges, one leaked, the black was only half full after I put in a new one. I suspect 2 cartridges were defective as the ink that spilled was blue, but the black one was the one that was half full after the replacement. Also, I didn't know I had to order PGBK when I originally ordered replacement cartridges. That ended for now, and since I brought everything to the Caribbean, I can't find a replacement here. I will order a large batch but I really hope they are all full and don't run out when I put in a new one. Hopefully in the future they will be full and not half full. This has never happened before and cartridges are expensive.
