The new HSM AF500 L4 paper shredder is quick, secure and efficient in destroying your high volume shredding jobs. This shredder is designed for destroying paper and also small quantities of credit and charge cards as well. The sturdy cutting rollers also hold up to paper clips and staples- however these are not advised to be shredded when used with the automatic feeder. The AF500 L4 has an automatic feeder that can be used with up to 500 sheets of paper at once. The feed is also locked and can only be opened by a specially programmed USB stick that has to be inserted into the machine. The USB sticks are not interchangeable, which means that only the stick that you received with your machine can be used with it. This helps to prevent any unauthorized access from obtaining your secure materials. The AF500 is very user friendly. The LED light next to the USB socket informs you about the status of the machine. It can specify if the machine is loaded with paper, unloaded, locked or unlocked. This makes for easy indications about the status of the paper cassette. The machine features 3 function modes that will come in handy while using your machine. The permanent mode will continuously run the unit until you shut it off, or a two minute period has passed where no materials have been fed in. Standby mode also occurs when no materials are being fed into the machine. This machine features an EcoSmart standby mode where a power consumption of only 0.1 watts is used. With such user friendly and efficient features, the AF500 L4 should be your next office purchase.
