After a large batch of scanning items into my paperless office, my shredder seemed to be jamming more than normal for my assistant. After helping her clear the stuck paper I got to wondering if there is a way to minimize the jams. Fellowes claims they have created a jam proof shredder. It look like it basically just stops before the paper gets packed in so tight that you can’t remove it. Has anyone used one of these? Do they work very well?
