For the third time I have bought a Staples Shredder Model # SPL-TXC10A and again I am having problems with it. When I turn it to Auto, the power won't come on again. Is there a reset button on this unit. I have only had it perhaps 3-4 months and just shred mail. Nothing heavy that would put strain on the motor. Any ideas on how to get the power to work? Thanks, Randy
