ABSTRACT:
A cleaning device for cleaning the outer surfaces of a row of ejection nozzles integrated in at least one print module of an ink-jet print head of a postage meter having a base including a cleaning member for wiping the ink ejection surfaces, the cleaning member being mounted on a support member which is movable, by actuating a drive member which is linked to a connecting-rod and crank system, between a first position in which the cleaning member is remote from the print module and a second position in which the cleaning member has wiped the outer surfaces of the ejection nozzles. The cleaning member is mounted on one end of a sweeping hinged lever and include a compensating support member, having respective springs, each carrying a set of independent wiping brushes, in order to transform the initial circular movement of the support member into a rectilinear movement of the brushes in contact with the ejection surfaces of the print module.
