ABSTRACT:
In a parallel setting device for a print head carriage guide relative to a print medium support (6) in printers, in particular in matrix printers, the print head carriage guide includes a parallel disposable and position adjustable carriage guide axle (5) relative to the print medium support (1) and disposed rearwards relative to the print medium support at the printer frame 1 and a front carriage guide axle (4) adjustable to a minimum distance and disposed opposite to the print medium support (6). The rear and the front carriage guide axle (4,5) in each case are supported in the side plate (2,3) of the printer frame (1). The print medium support (6) is disposed at a level different to that of the front carriage guide axle (4). In order to find a simple and more precise operating solution, which is based on measurable part steps, it is recommended, that the rear carriage guide axle (5) is supported in the side plates (2,3) with cams rings (13) and a parallel positioning between the print medium support (6) and the print head carriage guide is adjustable by one-sided lifting and lowering of the rear carriage guide axle (5).
