Using a staple gun is a great way to fire a lot of staples super quickly. But getting a staple jammed in the gun can really disrupt your flow, especially if you still have a lot left to staple. Fortunately, unjamming a staple gun isn’t hard, and you only need a screwdriver and a pair of needle-nose pliers to fix most models. If you have any concerns, consult your owner’s manual to figure out what your staple gun needs.

  2. Use a screwdriver to remove the screw at the bottom of the stapler. Once the screw is out, reach in and remove the staple gun’s magazine. It should slide right out without any problems. [2]

  1. Unplug the staple gun before you try to fix it to avoid any injuries. Look for the release lever on the very bottom of the staple gun. Pull on the lever to unclip the magazine, then pull the magazine out of the gun. [7]
  2. Some jams are caused by staples failing to properly leave the magazine. If you notice your staples are crushed by other staples, use needle-nose pliers to gently unstick the jam. [8]
  3. Check out the discharge area to look for staples that aren’t in the magazine, but haven’t actually discharged. Use a pair of needle-nose pliers to reach the jam and pinch the staple to remove it. Work slowly and try to be gentle so you don’t accidentally damage the staple gun in the process. [9]

Why does my stapler keep jamming?

  1. Firing a staple gun super quickly can cause the staples to stack on top of each other and jam the gun. If your staple gun jams a lot, slow down your stapling to a more moderate pace. [10]
  2. Staples come in different sizes (usually small or large). If you’re using the wrong size, it could cause your gun to jam. Check the owner’s manual to find out which staples you should be using for a smooth stapling experience. [11]

  1. It’s easy to put the staples in upside down and accidentally jam the stapler. Slide your staples into the magazine with the flat side down and the sharp edges pointing upward. [12]
    • This is true for most staple guns, but it could vary depending on the model you have. If you’re not sure, check your owner’s manual.
    • Be sure to note the end of the staple gun where the staples are supposed to come out of, since it's not always located where you might think.
    • The tool is often marked with an arrow of where the staples will come out.

    To avoid that, I always load my staple gun from the back using a full sleeve of joined staples, since using smaller broken bits of staples tends to jam more.
