Did they totally dry out?  I suspect that is just ink in the corners, not necessarily dried of overly concentrated inks.

If they have dried, I'd recommend buying new carts. When a cart is empty there is still residual ink in the corners.  If the printer had sat for a year, then it might be time to start over.  If you just ran the carts empty and it has sat even months, I doubt the ink in the corners of the carts is bad ink.

Probably so if they are still liquid.  I've never seen a cart actually dry out inside.

If they are dry or if we're talking about ink that is years old, then you may have a problem.
