It wouldn't come from Ricoh. We got them from GBC. In the environment that you describe, the ProClick is really for binding the pages that were punched by the Ricoh with GBC StreamPunch. Just like a 3-hole punch option, you still have to take the pages from the MFP and put them into a 3-ring binder. The P3000 is the device that applies the binder to the punched sets. Yes the P3000 does punch but mostly just to get special front and back covers punched.
Attached is a video of the P3000 in action.
