On my 3880 there is an option to do a test print where on a plain sheet of paper you get to see if all the cartridges are printing properly. If they are then "all the dots/lines" are connected. That is, there are no gaps in the dots for every ink color.
Every now and then there are gaps between the dots. When this happens, I just run the test again (maybe twice) and I usually find that all the dots get re-connected.
This is much cheaper than running a longer test print which obviously uses a lot more ink. However, when the quick test prints show that the heads are still a bit clogged, I just run a small sized (10x15cm) print and this also seems to unblock the heads.
