Which also means you're printing frequently enough to be worth the maintenance hassles. Less frequently, you're better off sending out to a service (says guy who still has a pile of wet darkroom stuff).

That's the beauty of dye sub, the maintenance is pretty simple. You can buy a brand new roll, print only 2 images, and then leave the thing sitting there for a year and the next print will come out the same.

This is from experience designing/operating photo booth kiosks based on dye sub printers.
