Abstract

A method and device for output of single sheets from a printer employs a driven first roller pair having a conveying nip in which a respective single sheet is transported and deflected from an approximately vertically proceeding conveying path into an approximately horizontal conveying path. A separation element that suppresses a continued conveying of the respective single sheet on a circumferential surface of a lower roller of the roller pair is arranged in a proximity of the circumferential surface of the lower roller. An edge sensor is arranged preceding the roller as viewed in a conveying direction for determining whether single sheets have pushed on top of one another. A discharge brush electrically discharges one side of the single sheet arranged in the conveying path following the roller pair. A deflection device deflects the single sheet emerging from the conveying nip into a substantially horizontal attitude shortly before the conveying nip as viewed in a direction of the conveying path. The discharge brush is mounted to the end of the deflection device.
