Abstract
A sheet separating mechanism and a method of separating sheets is provided to prevent the multifeeding of sheets into printers or copiers. The sheet separating mechanism provides a first nip and a second nip for feeding a series of sheets therebetween. The first nip can include a first motor and the second nip can include a second motor for feeding a leading sheet from the first nip to the second nip. The mechanism further provides a first sensor for sensing a trailing edge of the leading sheet and a second sensor for sensing a leading edge of the leading sheet. The first sensor is upstream of the first motor and the second sensor is downstream of the second motor. A trailing sheet can be prevented from feeding with the leading sheet by stopping the first motor when the leading edge of the leading sheet is sensed by the second sensor while simultaneously the first sensor remains occluded.
