When used in conjunction with WorkForce document scanners- the Epson Network Scan Module takes the place of your scanner's control panel. Just remove a few screws- using the included screwdriver- to unlock the front control panel on your scanner- and replace it with the Module. Now- your scanner has the capability to scan to- and be controlled by- any PC that's within the same sub-network and has Document Capture Pro software installed. Document Capture Pro comes standard with all compatible scanners. For use with the WorkForce DS-6500 / DS-7500 and WorkForce DS-50000 / DS-60000 / DS-70000 document scanners.
