Keep in mind that a shredder needs time to cool down between sessions and will break down if it is kept running continuously. To prevent this, consider purchasing a shredder that will be able to handle slightly more work than needed. This way the shredder won't be running at maximum capacity all of the time and the life of the machine will be increased.
There are two main ways that a shredder destroys paper. Strip-cut shredders cut paperwork into thin strips of 1/4 of an inch or smaller. This option suits the security needs of most offices. Cross-cut shredders are more suitable for the most confidential documents. This type of shredder cuts both lengthwise and widthwise to create what looks like confetti, and these shredders are often referred to as "confetti paper shredders."
Commercial paper shredders need regular maintenance to run at their optimum rate. Lubricating oil must be applied to the shredder regularly to remove the build-up of paper dust inside the cutting apparatus. Most paper shredder manufacturers will recommend particular oil for their machine. The oil should be applied regularly depending on how often the machine is used. General repairs like paper jams can normally be handled by the office staff.
