Parts that are usually needed to repair a paper shredder include replacement gears, shredder blades, circuit boards and even a new motor. Any defect or damage to these parts can cause a paper shredder to jam, make too much noise or stop operating completely.
If a paper shredder is still under warranty, the repair needs to be done in an authorized service center. Such centers have access to high-quality and genuine replacement parts for various paper shredder brands. Individuals who would like to repair a paper shredder on their own can purchase replacement parts from office supplies stores or order them online. The replacement part must be compatible with the brand and model of the paper shredder being repaired.
