SOURCE: Swingline Stapler Staples Only After You Open It Up....

When you lift up the top of the stapler (as though you are going to put staples in), does the pusher slide freely back and forth? It might be getting stuck at some point and not pushing the staples (either due to a worn pusher spring, or friction). First (after removing the staples) try spraying some light oil on the mechanism and lifting the top part of the stapler up and down a few times and observe how easily it moves back and forth. Also, with the top open try GENTLY sliding back and forth a little - if it slides fine with no sticking, try loading staples and using stapler. If it slides ok, but doesn't quickly return to it's "normal position" when pulled so as to put tension on the spring, rhen the spring may be worn and need replacing.

Hello there:
when you purchase staples for this particular gun even though you might get a staple that is says it fits this gun you need to look at the type of staple if you get the one that says heavy duty it will not work it took me 2 times to find out the right ones for this gun it comes in a green box and says standard duty on it not heavy duty this is where most people make their mistake. ok?
best regards michael
