Gentleman,
I came across this today and wanted to post it to save others some time and frustration:
On the 4 Series machines with PinPoint Scan 3, do NOT update firmware passed v3.07 as it breaks PinPoint Scan. Firmware v3.08 and 3.09 generate an error screen after inputting the PIN and rolling back to firmware revision 3.07 fixed the issue.
