My swingline electric stapler model 42130 is jammed is there a manual release button the one on the back doesnt work

Taking the stapler apart is a complex task if you can figure how to do that.To dismantle the stapler, slide back the top, remove two small screws on both sides, six on the bottom, four of the screws are under the sticker so you must peel off the sticker, you must also remove the sticker on top. There two tiny shinny screws at the bottom once you are inside. Now you have access to more screws you can take off to get to the staples place where the jam is. Watch cables where they are plugged to in case they come off. If you are are a mechanical technician or technically inclined you might be able to fix this yourself but you must be very patient.

I just took this model apart. The battery cover slides off. There are two scews on the side and 6 on the base i think. 4 our hidden under the sticker. This will get you inside to see where it is jammed.
