Why is having a high-quality paper shredder important for my business?

Security breaches occur when unauthorized persons access paper documents Businesses that want to boost their security and prevent identity theft should, therefore, invest in high-quality paper shredders In addition, some industries and companies, such as healthcare facilities and accounting firms, may have regulatory requirements to maintain data security.

What are the benefits of a cross-cut shredder?

One of the key advantages of cross-cut shredders is that they produce small paper particles, which makes them more secure than other forms of shredding This is critical for firms looking to destroy papers containing sensitive data, such as Social Security Numbers and medical PII data Cross-cut shredder waste also compresses more than strip cuts and requires less frequent emptying.

Why do I need to oil my shredder?

Over time, shredders accumulate dust and residue which can cause paper sheets to stick to the cutters Shredder oil prevents this from happening and works to promote optimal operation It does this by softening packed dust and preventing sticky residue This allows the paper to travel freely through the cutter’s head.


What is the best way to unjam a paper shredder?

Before unjamming a shredder, make sure it is switched off and unplugged Then empty any waste and remove the shredder’s lid Dispose of any paper from the shredder’s head and blades If required, carefully remove stubborn paper shreds using a screwdriver. 

Before continuing to use the shredder, make sure it is functioning properly by feeding it only one sheet of paper If the shredder remains jammed, lubricate it with a small amount of oil and repeat the above steps.
