How do snowbirds protect Epson printers from freezing?

Preparing to head south as a snowbird -- have Epson inkjet printers and Epson ecotank printers.

How do snowbirds prepare Epson printers so the ink doesn't freeze and hurt the printhead?

Is there a way to drain the Ecotank ink. What about the ink in the Epson printheads?

 

I have no idea what a snowbird is. Never heard of it.
Generally speaking I'd pack the body of the Epson as it is - assuming it will be put back into use on arrival.

 

Thanks.
I'm leaving the Epsons up north in an unheated building for the winter. Will the Epson ink freeze inside the printhead if it goes down to 10-20°F?

 

It is quite possible. Among other issues the cold might cause to the heads. However, there's no way to fully purge the print head.
Removing the heads is a challenge in itself, as they're spring loaded into the nozzle assembly. Many a printer have tried to replace their own print heads, only to spray highly pressurized ink all over themselves and their shops.

Might be best to budget ahead for new heads. Remove the cartridges of course, and maybe with some luck, and a couple days in some warmth, the machine will function once more.
