PIXMA G3630 wont print since I topped up the ink

[Fancypants]

I recently topped up my black ink cartridge (for the first time since I got the printer) and now it won't print. I also topped up other colours and they are fine. Everything comes out blank for black.   Any help would be greatly appreciated.
