I have not used a Lee, but I have a Primer. My dryer has a 2 sided chrome plate, each side has a canvas curtain that is clamped down to hold the print in place as it drys and a thermostat to control the temperature. For glossy place the print face down on the plate, for matt face up facing the canvas. For glossy the chrome plate must be clean, I soak the print in distilled water and the print drys until it will pop off. I use my dryer for working prints as the canvas may become stained, occasionally I want a fiber archival glossy print in which case I do not use the heater or the canvas. I put the print face down, work out any bubbles and let it air dry until it falls away from the plate.
Good luck
