💡 Why does my thermal press keep jamming on thick liner stock?

You really just need a tougher drive piece that actually bites into the media instead of slipping around.

- Grabs onto heavy backing layers without slipping during fast peel operations

- Keeps registration marks aligned so your vision system never misses a mark

- Takes the stress off drive belts so your rig stays cool during marathon shipments
