The print pin drive device group (3) and a print pin guide device group (5) with a casing (8) guiding the print pins (7) is provided with an adjustable print pin guide (2) at a matrix pin print head (1). An electric lifting magnet (9) with set screw (12) for the magnet core (13) is disposed in the regiion of the print pin guide device group (5). The magnet core (13) forms together with a pin guide carrier (15) an adjustable magnetic discontinuity air gap (14). Therefore, the pin guide carrier (15) is movable back and forth between two fixedly adjustable positions. In order to provide for a precisely operating print pin guide, which is also suitable for shorter, more bend-resistant print pins, behaving stiffer against bending, it is disclosed that the electric lifting magnet (9) is disposed with its coil center axis (16) perpendicular to the center axis (17) of the matrix pin print head (1) running perpendicular to the print direction of the print pins (7) and that the magnet core (13), movable in a guide, is connected with a parallel adjustable pin guide carrier (15).
A matrix pin print head for disposal opposite to a print counter support and having a center axis comprising a print pin drive device group;
A matrix pin print head (1) with adjustable print pin guide (2), where a print pin drive device group (3) and a print pin guide device group (5), disposed toward a print counter support (4), are provided with a casing (8) guiding the print pins (7), and wherein an electric lifting magnet (9) with a set screw (12) for the magnet core (13) is disposed in the area of the print pin guide device group (5), which magnet core together with a pin guide carrier (15) forms an adjustable magnetic discontinuity air gap (14) and whereby the pin guide carrier (15) is movable back and forth between two fixedly adjustable positions;
A control method for positioning pins of a matrix pin print head for disposal opposite to a print counter support and said print head having a center axis comprising the steps:
