Common Staple Gun Problems and How To Fix Them


Common Staple Gun Problems and How To Fix Them

Power tools such as the staple gun are excellent tools to have around. They’re diverse in their uses, and they give us the ability to make quick work of even the most grueling projects. However, it’s essential to remember that staple guns can break—and when they do, we should know how to address them. Check out these common staple gun problems and how to fix them so you can make the most of each project.


Whether you’re working with an automatic, pneumatic, or electric staple gun, one issue you’re sure to have with all of them at some point is jamming. So, let’s take a moment to explore what constitutes a jammed staple gun. Jams usually occur when staples get cramped, bent, or wedged in the very top of the gun head.

This makes it very difficult or even impossible for the tool to function correctly. So, if you find that your staples aren’t firing properly, your device likely has a blockage. This is a common problem, so don’t worry if it happens to you. There are various ways to resolve it.

Solutions for Jamming

Luckily, unjamming an industrial automatic stapler is relatively simple when you carefully follow the steps. The process is going to look a little like this:

  • Slide out your gun’s pusher rod (the bar that extends along the magazine of your tool.)
  • Unscrew the bottom attachment of the magazine and remove it from your gun.
  • Check for stray staples and other blockages.
  • Clear the jammed staples using needle-nose pliers.

Once you find the issue and remove it, double-check your staple gun is still working correctly by firing a round of test staples into scrap material.

Dispensing Too Many Staples at Once

Another issue that occasionally plagues staple guns is the tool trying to dispense more than one staple at a time. So, when you go to fire your gun and find you can’t secure your materials because several staples are falling out of the nose, then you’ve got a problem.

This is an issue for any heavy-duty stapler but can cause severe complications if you’re using an electric or pneumatic one. Because there’s more power behind them, when an electric or pneumatic stapler tries to fire too many staples at once, it can cause parts of the tool to bend, damaging the entire model.  

Solutions for Dispensing Too Many Staples

Take a moment to evaluate certain aspects of your staples and your gun. This can be beneficial in understanding how to fix it. Of course, just like any other kind of jam or blockage, you should first disassemble the gun and empty it.

Next, do a little research on your gun and what kind of pins are the most ideal for the type of work it does. Review what kind of staples you’ve been using and compare them with the ideal caliber of stapler for your gun. Chances are that you’ve simply been using the wrong kind. Therefore, fixing the issue is as simple as buying suitable staples and reloading your gun.

Clogged or Misfiring Hammer

Clogged or misfiring hammers don’t exhibit themselves as obviously as you might expect. However, if you know what to look for, these issues can be much easier to address. You might have a clogged or misfiring hammer if your gun is doing any of the following things:

  • It’s unable to fully penetrate materials.
  • It’s releasing bent staples.
  • It isn’t releasing fasteners.

When you have a clogged or misfiring hammer, it can turn simple, safe tasks into hazardous situations. On top of that, it makes completing your projects on time much more complicated and time-consuming.

So, when you start to notice these kinds of issues with your tool, it’s crucial to do everything you can to resolve the issue quickly. Again, when a staple gun is blocked or jammed, it’s best to start by disassembling it and checking for problems that are easier to fix. Then, check if you’re using the proper size and caliber staples for your tool.

If you run those tests and your hammer is still sticky, clogged, or misfiring, then it’s time to check for other issues. It’s not uncommon for staple guns to build up grease and dirt over time. The hammer can also take a toll on the gun’s performance.

So, if you happen to find an accumulation of dirt or grime, use vinegar, degreaser, or WD40 to give your gun a polish. If you happen to notice that parts of your hammer are worn down and bent out of shape, invest in a new tool.

Inadequate Depth Penetration

Of course, your staple gun can also be tricky when it comes to properly penetrating your materials. The entire purpose of a staple gun is to secure your projects efficiently and adequately with staples. So, when your gun can’t pierce the materials sufficiently, it can cause the quality of your projects to suffer—or, even worse, the projects could fall apart entirely.

Sometimes these types of issues are due to blockages. But more often than not, it has more to do with using low-grade or incorrect kinds of staples. Or, just as likely, it might have something to do with the power output of your tool. So, researching these things beforehand can help to prevent issues like this from happening.

Solutions for Inadequate Depth Penetration

Suppose you start experiencing problems with your tool’s ability to penetrate your materials. In that case, check for some of the more prominent issues that might be causing the problem, such as the length, caliber, and size of staples you’re using.

You’ll also want to evaluate the materials you’re working with to see if a staple gun is the best tool to puncture it. Sometimes the best thing you can do is grab a drill or a screwdriver to handle the jobs that your staple gun can’t.

While staple guns are a fabulous addition to any toolkit, it’s important to remember they’re still fallible. So, when the time comes to perform some maintenance on your staple gun, we hope you’ll consider some of these common staple gun problems and how to fix them.
