Firstly, let me say that I'm new to this forum and I don't want to step on any toes. Maybe this has been addressed here or elsewhere (I confess to skipping some of the posts in this thread), but here's my two cents on the grounding issue.
Seems like the general consensus is that the grounding is taking place from the machine to the stand. I am by no means a scholar on the subject, but there shouldn't be a discharge of electricity to the stand when the machine is grounded to the electrical socket. I always figured it was grounding the stand to the machine (and, thereby, the machine's electrical ground) in order to disperse the static buildup from rolls of vinyl on the roller feed.
Call me crazy, but that's what makes sense to me.
Again, this may have been covered before and I just didn't see it.
