Vintage Foothill 310, 3 Hole Punch. My hole punch does not entirely cut the holes.

Question edited for clarity.
Question moved from Cars and Trucks to model category.

Unfortunately, it looks like a one-off special. I would have thought it would bed a standard figure 8 two pin plug into the stapler

Not much on clearing jams. You could contact then direct. You will probably need to remove the base. Hit the punches with a centre punch. One thing you could try is spaying the punches and the document with WD40 and leave is overnight. My theory is that it will lubricate the punches and they will pop up. I would also suggest pulling out and tearing all of the sheets from the front one at a time. That will ease the friction.

There may be a latch that has been inadvertently engaged.

I wouldn't mess with a cord, you need to get a new machine.

Saundra, have you tried checking for paper jams?

by locked down I am going to assume you mean it will not go back to the normal postion when it is not making a hole. this can be caused by too many of the scrap pieces of paper that are left from making the hole. clogging the punch area. remove all the excess pieces of paper that may be stuck in the whole punch, then try again, you may have to pry the handle and or push and pull it until it releases. do not use again until the handle moves smoothly, clean the areas around the punch.

Thst is a hole punch home position sensor not detecting the 2 or 3 hole punch.
Try reseating the hole punch assembly then power the machine off and on.
