Hi ya'll, working on a MJ-6101 punch unit, and need to order the punch itself, I can find it in ribbon, but not a downloadable copy, there are at least 8 different versions of the part number, and not real sure which one is the correct number for USA machines, the last one in ribbon is 6LB42768000 and that's on page 3 part# 1D-1...so not real sure, any ideas??
