Abstract
In arrangement for keeping clean the nozzles of an ink print head with a large number of nozzles, the printhead having an ink print module or of several ink print modules assembled in stacked construction, and a seal bonnet and a wiping lip arranged positionally on the ink print head, a cleaning module is provided alongside the ink print modules on the ink print head, and the seal bonnet is flexibly positioned on the ink print head and is formed so that the front surface of all the ink print modules, as well as the front surface of the cleaning module, can be simultaneously covered. In addition, the seal bonnet is kinematically coupled with the wiping lip. Cleaning ensues by expelling ink and/or suctioning ink into the seal bonnet, and subsequently emptying the seal bonnet of ink, and mechanically wiping off the ink print head.
