This is the part where I get to point out that Brother inkjets do a little dance ~every day that keeps the heads fresh. They do this on their own as for long as they're powered up.

This allows them to work well even if years go by between prints. It's a very thoughtful design element.

(They don't survive sitting for months and months unpowered on a shelf very well, but... you'll have that.)
