Abstract

A device spray cleans an inkjet print head. The purpose of the device is to avoid the formation of stalagmites during spray cleaning and therefore also to improve the print quality as a result of the fact that the transport device for the print carriers or items of mail is soiled as little as possible. This is achieved by a relative movement of a baffle element in a flat space or in a plane parallel to the nozzle surface of the at least one inkjet print head in conjunction with the spray cleaning.
