I use an Omega Drum dryer for my fibre prints. I place the prints face down on the canvas. There are two controls, one for speed, and one for temp and I think that I have the speed set to about 1/3 full speed, and the temp set to about 1/2 full temp. I arrived at these values through trial and error - I set the temp to about 1/2 which seemed to be the lowest temp that I could use to get fully dry prints, and then used the fastest speed which would result in a dry, flat print.
