Fellowes' Intellishred™ series eliminates jams and prevents overloads by calculating the amount of paper being fed into the shredder. A sensor measures the thickness of a paper stack and automatically stops a paper jam before it occurs. The shredders also detect when paper has been misfed or fast-fed by turbo-powering through the job or reversing the paper for easy removal. SafeSense™ technology disables the shredders when sensing hands or when pets are too close to the paper opening. SilentShred™ technology features a whisper-quiet motor.
