This happens more often than you might think. In a survey involving over a thousand Which? members, 43% have experienced a blocked shredder. Members also have some pretty varied ways to solve the problem – find out which we recommend below.
1. Let it cool down
If you're shredding lots of paper and not giving your machine enough rest between batches, then the motor can become hot and stop working.
Overheating isn't as prominent a problem as blockages, with 18% reporting it as an issue they've experienced, but it's common enough to be aware of.
The first thing to try if you're having shredder issues is usually to unplug it and let it cool down before trying again. Check the instructions provided with your shredder to see how long you should leave it for – one of our most recent Best Buys required a 40-minute rest between 10-minute batches, which was similar to other models on test.
2. Cycle between reverse and go function
Most shredders will have the option to reverse, which is designed to help avoid jams. But don't just hit and hope – 30% of people have found success when constantly alternating between the reverse and forward functions.
This may result in a messy clump of paper, which you'll need to carefully remove in order to effectively clear the machine.
Don't do this for too long though, or too quickly, as it can be quite demanding on the machine and may run the risk of it overheating.
3. Empty the bin
Another reason your shredder may jam is there isn't anywhere for the paper to go once it's shredded.
It's awfully simple, but even if it doesn't look completely full, try switching your shredder off and emptying the bin. 13% of people resolved their jam with this method. Just make sure you're recycling whatever you shred, as it will be used for products like, toilet paper, coffee filters or towels, to name a few.
ost shredders tend to be between 13 and 16 litres, though we have tested shredders with bins as large as 32 litres. Check our expert reviews of these4. Use card to push through a jam
If the solutions above haven't worked, it may be worth trying to use card to remove the blockage. Ironically, feeding a shredder more can help clear a jam!
For this to work, you'll need a stiff and tough bit of card, similar to that of a cereal box. Take care not to use card that's too thick, otherwise you could make the problem worse.
While the shredder is on and running, carefully push the card with some pressure to help squeeze out the blockage. You could also try folding the card into a point, so it's easier to position near the area that's blocked.
While this wasn't the most popular method, with only 4% per cent finding success, it's definitely worth a try.
5. Use a shredder lubricant to prevent paper jams
Another way to prolong the life of your shredder is to use a lubricant. The purpose of lubricating your shredder is to prevent jams and facilitate the smooth passing of paper, and in fact manufacturers like Fellowes insist that you lubricate your shredder every time you empty the bin, or at least twice a month. Despite that, 69% of respondents don't do this at all.
It also seems to make a real difference, with nearly half of those who lubricate their shredder thinking it made their device more resistant to jams. When selecting a lubricant, make sure you use vegetable-based oils instead of aerosol oils, since aerosol oils are petroleum-based and can pose a fire risk.
Other responses from Which? members
42% of respondents found using tools to unblock a shredder the most effective method – but it's not something we'd recommend. Tools such as tweezers or needle-nose pliers could end up damaging the motor, the blades, or yourself.
it's a serious safety risk. shaking the shredder and spraying WD-40. However, some were even more extreme. A few said they would take apart the motor itself, which is also something we don't recommend. It may damage the shredder and void any warranty you have, and could render it unsafe to use.Three popular shredder models
