Abstract

In a cooling device for a printing substrate after passage through a fixing station, a transport path is provided for the printing substrate. A first cooling unit is provided along one side of the transport path. The first cooling unit has a first perforated plate facing towards the printing substrate, a coolant being conducted through the perforated plate. A second cooling unit is provided along an opposite side of the transport path. This second cooling unit has a perforated plate on a surface facing towards the printing substrate. A coolant is conducted through the perforated plate onto the opposite side of the printing substrate. A nip unit for the printing substrate has a nip roll integrated into the second cooling unit such that the nip roll is cooled by the second cooling unit.
