How to Fix Common Paper Shredder Problems?

Click on the shredder problem you are experiencing

You are in the middle of your shredding session. It is you together with a paper shredder against that growing pile of old but confidential documents that were collecting dust on your desk. Your shredder is doing its job grinding through the papers, but then all of a sudden, the shredder stops working. The sheets you just fed to the shredder are half shredded, half readable, and are patiently waiting for you to solve the problem. Now what?

Like with all household items or office appliances, paper shredders can have issues that need to be fixed. These issues can present themselves in various ways.

That is why it is sometimes difficult to pinpoint where the problem is coming from, mainly when the shredder isn’t operating at all or indicating a problem that you already tried to fix yourself. For instance, a blinking LED icon for a full paper bin, even though you just emptied the wastebasket.

1. My shredder has jammed. How to fix and unjam a paper shredder?


Symptoms of a Paper Jam

How to unjam a jammed paper shredder? A jammer or clogged shredder is one of the most common and annoying problems a paper shredder can have, and it can present in a variety of ways, depending on the model and make of the shredder.
Some higher-end shredders have a light indicator that shows the users when it is jammed or even when it will jam due to exceeding the maximum load. However, paper jams are usually not too difficult to solve by yourself.

If your shredder is jammed or clogged, it may present with these symptoms:

  • Not fully shredding the paper.
  • Getting stuck in the reverse function.
  • Making strange grinding or high pitch noises.
  • Not pulling in paper or only pulling it on one side.
  • Paper shredder stops working in the middle of a shredding session.
  • Blinking indicators that informs you about the paper jam.
  • The shredder only works in reverse.

Quick Fix

Fixing a paper jam, there are several things you can do but remember NEVER to put your fingers near the blades or feed opening. Also, check your shredder’s user manual to see what kind of tips the manufacturer gives you to solve the paper jam.

Before you turn off the clogged shredder and go near the blades, try using the reverse function most shredders have. The reverse function can, in some cases, solve a simple jam. If this doesn’t help or your shredder doesn’t have a reverse function, try turning it off and unplugging it.


Then you can start to carefully pluck the paper shreds causing the jam out from the blades with a pair of tweezers. In some cases, gently running a vacuum cleaner parallel to the edges (within proximity but not touching them) can suck out paper dust and particles, which can cause a jam as well.

2. Help! My shredder stopped working. Can paper shredders overheat?


Symptoms of Overheating

Do you have a shredder that won’t shred? Many people don’t realize that most paper shredders have a maximum run-time because their motor gets warm from shredding. The maximum run time means that if a shredder is used for a long time consecutively, the machine will eventually shut off to cool down.


The maximum run-time and cool-down period differ per shredder, but these are usually specified in the user manual for your device. There are also paper shredders that can run continuously, so there is no maximum run-time. These are heavy-duty type shredders and industrial paper shredders.

So, if your shredder has suddenly stopped running in the middle of a shredding job but doesn’t appear to be jammed, the chances are that it is taking a break to cool down. It will start up again, usually within the next 30 minutes after leaving it to cool down.

If your shredder does not start up again after the defined cool downtime, it could have a different problem, such as a paper jam or a full paper bin, which are both easily solved. However, the worst-case scenario for a shredder is when it has a technical or motor flaw, for which you will need to contact the manufacture. But let’s hope this is not the case.

Quick Fix

Unfortunately, if your paper shredder has overheated and decided to take a timeout, you cannot do much. The shutdown is a security measure of the shredder to prevent damage to the motor of the machine. The best thing you can do is leave it alone for a while (check your manual to see how many minutes) and try again later. Also, in the future, try to prevent it from overheating too often.
If your shredder overheats often, it is probably a sign that you need a more heavy-duty shredder, which better suits your needs and can handle shredding larger amounts of paper for a more extended session. Nevertheless, here are some sources that provide more information about the matter.

Sensor Problem

3. My shredder has a mind of its own. Is there something wrong with its sensors?


Symptoms of Sensor Issues

Sometimes paper shredders can have problems that cause them to act as though they are haunted or have a mind of their own. What is meant by this is that they may not stop after shredding (continually running in “Auto / On” mode), randomly start shredding by themselves, or indicates that the paper bin is full or the door is open when they are not.


These problems can be related to an issue with the shredder’s sensors and are usually triggered by dust or dirt, which partially block one or more of them. Cleaning these sensors usually does the trick and resolves the problem.

Quick Fix

The most straightforward way to fixing these problems caused by a dirty sensor is to clean them, but this may not be as easy as it sounds because the sensors can be hidden inside your shredder.

A paper shredder can have several different sensors. Most of them are safety precautions for the user or to prevent the shredder from damaging itself.

High-end shredders have various sensors and indicators, but the main ones are:

  • Load indicator sensor – registers when paper is being inserted.
  • Bin / bag full sensor – indicates when the paper bin is full.
  • Door sensor – shows when the paper bin or door is not closed or properly attached to the shredder.

Cleaning a dirty sensor is not always an easy fix because different shredders have sensors in different spots, and some are easier to reach than others. However, the sensors’ location can generally be found in the user manual, and once you have found the sensor’s location in the manual, you can proceed to turn off the shredder or unplug it completely.

Afterward, using a flashlight, you can search for the sensor on the shredder and use a vacuum cleaner, microfiber cloth, straw, or pipet to clean off the dust and dirt. After the sensors are clean and the shredder put back together, you can turn it on again, and hopefully, the problem is solved.

Weird Noises

Symptoms of Needing a Maintenance

Maintenance is essential for shredders used frequently, such as paper shredders used in an office environment.

  • Shredder hesitating to start or producing high pitched noise, grinding noise, or more noise than usual.
  • Paper shredder runs slower than it used to.

Quick Fix

The proper solution for these symptoms is giving your office or home shredder well-earned and thorough maintenance. Maintenance for your shredder in this situation ultimately means giving it a deep cleaning.

  1. This process should be started by briefly activating the reverse function to loosen up any paper fibers or particles left behind.
  2. Then turn off or unplug the shredder and clean the paper bin.
  3. After you have emptied, cleaned, dried, and placed the container back, you carefully vacuuming along the opening slit where you usually insert paper, but make sure not to touch the shredder’s blades.
  4. Using a vacuum will remove any paper dust left between the blades and the edges of the opening.
  5. The final step is lubricating the blades of the shredder with official shredder oil. This will help your shredder’s blades move smoothly and shred well.
