The difference between a StreamPunch III and the Pro is:
Provides a new heavy-duty clutch for stronger punching capability.
Bypass mode allows media that are supported by the printer to be by-passed directly to the SR5000 Finisher, the SR5020 Booklet Finisher, or the SK5010 High Capacity Stacker. The StreamPunch III added an unnecessarily long paper path to un-punched paper.
The StreamPunch Pro includes new optional heavy-duty Pro die sets. These die sets:
· Last up to 8 times longer than traditional die sets
· Support 19-hole CombBind, 44-Hole ColorCoil, and traditional 3-Hole Ring Binding
· Require less maintenance due to a unique encapsulated oil carrier that retains lubrication
