US 5,957,598 A · Printing device with an aligning station for printing aligned receiving sheets on both sides

Abstract

A printing device for duplex printing of a sheet, comprising a feed path for feeding an unprinted sheet and a return path for returning a sheet printed on one side in an inverted orientation to a part of the feed path which is provided with an aligning station for aligning a supplied unprinted sheet and a returned sheet printed on one side. The aligning station comprises two aligning mechanisms which are disposed in spaced relationship in the feed direction and which each comprise two activatable transport nips which, as considered in a direction transversely of the feed direction, are situated a short distance apart so that a sheet fed between the nips can be aligned against one of each of the two transport nips by lateral transport and turning.
