I thought Brother Inks were dye inks, and not pigment so not suitable for yolo transfer paper.

I thought so too, but the shirts I printed with OEM Brother inks in the MFC-J6510W, whatever they are, onto Jetpro SS paper are standing incredibly well to repeated washing with very hot water and detergent then hot tumble drying. I washed my test shirts within an hour or two of printing too. And sometimes hot washed and tumbled dried twice on the first day, then every day for a week before wearing them normally. Colours are still bright and vibrant. Maybe not as nice as the ones dye subbed into cotton, though. Those look like they were dyed in a factory.

So I still don;t know what sort of ink comes with that printer - I just know it is excellent for printing with Jetpro SS paper.
