Do paper shredders need some kind of installation or configuration?

Not at all. Although they are electrical appliances, there is practically nothing to do but shred, once you have them plugged in. Simply press the power button and insert the paper or other written material into the corresponding slot so that the shredder starts working immediately making specific cuts.

What kinds of cuts do paper shredders make?

As is often the case with office appliances, not all paper shredders are the same. This means that not all sheets or documents are shredded in the same way. Usually, there are different types of cuts made according to the needs of the users. However, it is possible to identify 4 classes of cuts that appear in various models, as shown in the following table.

An example is cardboard, cardstock and transparent sheets. It is also very common that today’s shredders have special slots for CDs and DVDs.

What is the reverse function of a paper shredder?

When working with large volumes of paper on a daily basis, it is normal for shredders to stop working whenever paper jams occur. Paper jams sometimes originate from staples or paper clips that pass through the crusher. The reverse function, therefore, allows the cutting mechanism to reverse the motion to clear the jam and reset the device.

How do you measure the level of confidentiality offered by paper shredders?

If what concerns you most is the privacy and confidentiality of the information you are shredding, it is logical that you will lean towards models that offer the highest standards of data security. This is generally measured based on the number of pieces that a paper shredder generates from a single sheet of paper.

Paper shredders have a classification by levels, ranging from P-1 to P-7. This classification indicates the size of the pieces, in the case of particle cutting, and the width of the strips, for strip-shaped cutting.

What safety measures do paper shredders offer regarding their use?

Using paper shredders is relatively simple, as we have explained, but this does not mean that you do not need pay attention to its operation. Like any electrical device, there is always the possibility of common accidents or breakdowns. Because of this, there are certain security measures that you should observe.

  • It should have a reverse function to avoid paper jams.
  • The trash can (the waste container) should have a safety lid that stops the shredding action if it is full.
  • The shredder should stop automatically every time it becomes too hot.
    The safest ones also have access codes to access the wastebasket, keeping the pieces away from the wrong people.

Do all paper shredders have wheels?

Not all. This feature is very useful, since paper shredders with wheels facilitate their movement and mobility around the office or in homes. If, for example, you do not use the shredder every day and you need to store it, having wheels allows you to take them to the part of the office where it is needed to destroy the relevant documents.

Do paper shredders contribute to taking care of the environment?

Yes, because they help with recycling. Companies and offices generate a lot of garbage, mostly in the form of paper documents or cardboard items. Therefore, with a paper shredder we can shred folders, index cards, paper and other materials that occupy less space, to recycle them more efficiently.
