It sounds like powder is hanging up in the die or dispenser.
In my system, I had to clean everything with a degreaser. Then alcohol to get it fully dry. The o ring on the rotor needed wiped down with something slick. I think I rubbed just the o ring with wax on a cloth. Then to control static, I had to rub down the interior and exterior with dryer sheets. These do a good job with static.
Then after reassembly, I ran graphite through it. That is key to get it completely dry, but with some lubrication.
