My printer has been printing out blobs of black ink

My printer has been printing out blobs of black ink for awhile it started out small and now it's out of control. When I look inside there's ink everywhere. I've replaced my ink cartridges and tried to clean off the excess ink inside my printer but that didn't seem to help. Now when i print not only is there black ink everywhere but instead of the cartridges sliding back and forth smoothly when printing there being jerked.
