Common Problems with the Bonsaii C169-B 14-Sheet Shredder
Before diving into the troubleshooting steps, it’s important to understand the common issues that can cause your Bonsaii shredder to stop working. The C169-B is a reliable shredder designed to handle up to 14 sheets at a time, but like any piece of machinery, it can experience problems due to improper use, wear and tear, or mechanical failures. Below are some of the most frequently reported issues:
- The shredder doesn’t turn on.
- The shredder is jamming or not shredding properly.
- Overheating or excessive noise.
- The shredder is emitting a burning smell.
Let’s go through the potential causes of these issues and how you can fix them.

1. The Shredder Won’t Turn On
If your Bonsaii shredder C169-B doesn’t turn on, there could be several reasons behind this. Here’s a checklist of things to examine:

a. Power Supply Issues
Check the Power Plug and Cord:
The first thing to do is to check if the shredder is properly plugged into a working power outlet. A loose connection or an unplugged cord could easily be the culprit. Make sure the power cable is securely plugged into both the shredder and the power socket.
Power Supply Voltage:
Ensure that the power supply matches the shredder’s requirements. The Bonsaii 14-Sheet shredder is designed to work with a 120V AC, 60Hz power source. If you are using a different voltage or if your outlet is faulty, it may prevent the shredder from working. Test the socket with another appliance to confirm it’s working.
Overload or Power Surge:
If the shredder has recently been exposed to a power surge or is overloading, the internal fuse might have blown. In such cases, you may need to replace the fuse or contact Bonsaii customer support for further assistance.
b. Overload Protection Triggered

Check for Overload:
If the shredder is overloaded with too much paper or an incorrect material (such as plastic or CDs), it may trigger the overload protection. If the shredder’s overload light is on (in red), it means the machine has temporarily shut down to prevent damage. In this case, reduce the amount of paper being fed into the shredder and check for any blockages inside.
c. Faulty Power Switch or Internal Mechanism
If the power plug, supply, and overload aren’t the issues, the problem could be internal. It’s possible that the power switch or other internal components are malfunctioning. In this case, you might need to contact Bonsaii’s customer support team for repairs or a replacement.
2. Frequent Jamming or Poor Shredding Performance

Jamming is a common problem with paper shredders, especially when feeding too many sheets at once or putting in the wrong type of materials. Here’s how you can resolve frequent paper jams:
a. Reduce the Number of Sheets
The Bonsaii C169-B is designed to shred up to 14 sheets of paper at once. However, if you exceed this limit, the machine can struggle to process the paper, resulting in jams. Always ensure that you’re not feeding more than 14 sheets, and make sure the paper isn’t folded or too thick. If you’re shredding thicker paper, such as envelopes with windows or cardboard, try feeding them one sheet at a time.
b. Remove the Jammed Paper

If a paper jam occurs, the first thing you should do is switch the shredder to the “REV” position to release the paper. If the paper won’t easily come out, try gently pulling it out from the top of the shredder. If the jam is more severe, follow these steps:
- Switch the shredder to the “REV” (reverse) position.
- Pull out the jammed paper carefully.
- If the jam persists, repeat the reverse function for several seconds (2-3 times).
If none of this works, you might need to manually remove the paper from the blades using a soft tool like tweezers or a plastic knife.
c. Clean the Shredder Blades
Sometimes, bits of paper or dust can accumulate on the shredder blades, causing them to work less efficiently and eventually lead to jamming. Make sure to clean the blades every few months by running a shredder lubricant sheet through the machine. This will help keep the blades sharp and free from paper buildup.
3. Shredder Overheating
Overheating is another issue that can cause your Bonsaii shredder to stop working temporarily. The shredder has an overheat protection system to prevent damage to the motor.

a. Wait for It to Cool Down
If the shredder has been running continuously for an extended period, the motor might overheat. When the overheat protection kicks in, the red overheat light will appear. In this case, turn the shredder off and allow it to cool down for at least 30 to 40 minutes before attempting to use it again.
b. Prevent Future Overheating
- Avoid running the shredder for long periods at a stretch. Give it time to cool down every few minutes of use.
- Ensure that the shredder is not overstuffed with paper or items that are too thick, as this can cause the motor to overheat quickly.
4. Burning Smell or Strange Noises
If your Bonsaii shredder emits a burning smell or unusual noises while operating, this could be a sign of serious trouble. Here’s what you should check:
a. Excessive Load
A burning smell often indicates that the motor is being overworked. This can happen if you’re feeding in too much paper or thick materials, which strain the motor and cause it to overheat. If you smell burning, immediately turn off the shredder and unplug it. Let it cool down completely before you attempt to use it again.
b. Lubricate the Shredder
Another reason for unusual sounds or smells could be a lack of lubrication. If the shredder blades are dry, they can produce a squeaking or grinding noise. You should periodically lubricate the blades using a Bonsaii shredder lubricant sheet to keep things running smoothly and prevent wear and tear.
5. The Shredder is Not Shredding Properly
If your Bonsaii 14-Sheet shredder isn’t shredding as it should, the following issues could be at play:
a. Paper Quality
Ensure that the paper you are shredding isn’t too thick, folded, or damp. The shredder works best with standard office paper. Also, avoid shredding materials like plastic, adhesive tape, or cardboard, as these can damage the shredder’s internal mechanisms.
b. Empty the Basket Regularly

If the shredder’s waste bin is full, the shredder may struggle to operate efficiently. Empty the basket when it’s around 75% full to keep the machine running smoothly.
Remember, proper maintenance, careful usage, and regular lubrication can help prolong the life of your shredder and ensure it continues to perform efficiently. Happy shredding!
Conclusion
A malfunctioning Bonsaii 14-Sheet Shredder can be frustrating, but most problems are easily solvable with a little troubleshooting. Whether it’s a simple fix like unplugging the machine, reducing the paper load, or waiting for it to cool down, there are plenty of ways to get your shredder back up and running. However, if you’ve gone through all the troubleshooting steps and the problem persists, it might be time to reach out to Bonsaii’s customer support for further assistance.
