The paper is the cheapest part of sublimation. It's the ink that will kill you. When I do my "keep the print head open" prints I open my CorelDRAW and import a colorful photo, then shrink it down to about 2x2 and print on regular paper. It wastes the ink, but having to replace a printer is much more costly. I'm not sure what wastes more ink, the nozzle checks or just printing a small picture.
