We have a Screen 4300 and I am wondering if plates that have been loaded into the machine and punched by the machine, but never imaged, can be re-loaded, or if once they are punched, they are trash.
You can also rotate the play and grip from the other end even if the one end is punched. I have done that a few times if a corner gets kinked while trying to load.
I'm surprised it punched the plate before it yelled at you. We use just one size plate, same platemaker, but if for some reason a plate doesn't load correctly, it yells at me to take it out long before it gets to the punch stage.
