I've heard both complaints, you'd think the higher temperature wouldn't be
that hard to overcome. Pull the fuser from an old Brother laser and use
that for the transfer.
Obviously something different in the chemistry there... Might be like power
coat, the powder fuses at 200C (~400F) but once cured can easily survive
twice that temperature.
I guess it'll remain a mystery.
