Insert a stack of 600 letter and legal sheets and shut the lid. The Swingline® Stack-and-Shred™ 600M shreds it all automatically to micro-cut (Level P-5) size for high security. The paper chamber locks and requires four-digit PIN code to open. When shredding is done, it unlocks automatically and shuts down if inactive for two minutes. Intelligent Auto+® Jam Clearance automatically reverses and refeeds stuck sheets during auto feed shredding and Intelligent Interactive Jam Clearance uses LED lights to guide users through manually clearing a more complicated jam. The manual feed shredding slot can continuously shred nine sheets at a time. Place credit cards between the auto feed rollers and shut the lid to shred. DVDs/CDs can be shredded through a separate slot in the auto feed tray. Intelligent SelfOil™ automatically lubricates cutters. Intelligent Self-cleaning Cutters automatically keep cutters clear to prevent build-up that leads to jams. The 21-gallon bag frame waste bin should be lined with Swingline® shredder bags (sold separately).
