A ventilating device for ventilating a housing, includes first and second blowers, a flow chamber with an inlet opening, an outlet opening, and an equalization opening connecting the flow chamber between the inlet opening and the outlet opening with the environment, a freely movable cover element for partially covering the equalization opening in such a manner that passage of the flow is blocked in one direction but cleared in the other direction, and an ascending pipe. The elements in the ventilating device are arranged in the sequence first blower, inlet opening, flow chamber, outlet opening, second blower, and ascending pipe. The equalization opening is at least partially open at all times, so that the equalization opening displays a greater flow resistance than the inlet opening of the flow chamber.

A device and a method for applying and fusing a toner image on a substrate is described. The device has at least one printing unit, a transport unit for transporting the substrate through a print area of the printing units and a fusing unit for fusing toner on the substrate. The transport unit has an endless transport belt which passes continuously around at least two rollers to form a transport side. The fusing unit is in a transport direction of the endless transport belt behind the at least one printing unit and has at least one microwave applicator arranged adjacently to the endless transport belt for introducing microwaves into the substrate while the latter is being transported through it. With the method, a substrate to be printed is held on an endless transport belt and moved thereon through a print area of at least one printing unit and then through a fusing unit. In the print area of the at least one printing unit, a toner image is applied to the substrate, and inside the fusing unit the toner image is fused on the substrate by heating up the toner image by use of microwaves.

The invention relates to a delivery table ( ) for flat material ( ), in particular sheet paper, with a safeguard so that the material ( ) does not slide on the delivery table ( ). Exact and stable positioning of the flat material ( ) is achieved in that the safeguard to prevent sliding of the flat material ( ) is constructed as a surface ( ) disposed in the back area ( ) of the delivery table ( ), exhibiting high friction vis-&agrave;-vis the flat material ( ).

Delivery table

The invention concerns a stack height determination mechanism ( ) for a stack ( ) consisting of flat material ( ) with at least one sensor ( ) to determine stack height and a stack height control mechanism. Exact determination of the stack height, especially in order to exactly position the stack for the next delivery of material ( ), is achieved in that a flat element ( ) to determine the height of the stack ( ) is brought into a bearing position ( ) on the stack and that this bearing position ( ) is determined by at least one sensor ( ).
