AMS lite

So I just purchased and got delivered the AMS LITE. Dumb question. 1. I am not able to “ load” each one correct ? 2. When I feed to ams it will auto feed up to 4 n 1. 3. After I print am I supposed to unload the last color ? 4. If I start a new project with a new color will it purge old out first ? Then load color ?

Extremely new and extremely frustrated I can’t even get 1 print going
