One of the unknown benefits of inkjet printers is that if any of the ink colors runs out, that part of the printhead can get frozen solid as the ink that's left in there dries out.
After that, putting in a new ink tank won't overcome the block.
This is why most inkjet printers try to get you to replace the ink tank when it gets to the bottom of its load.
It's best to keep spares on hand, and buy a new one each time you replace a tank.
Generally, you can buy a new printer for less than it would cost you to repair it once you let the ink dry up in the printhead.
