Abstract (en)
Apparatus and a method for cleaning and maintaining an inkjet print head (12) with a maintenance head (14). The apparatus includes: an inkjet print head (12) translatable in a first direction; a device (28,30) for translating the print head (12) to a cleaning station (36); an inkjet maintenance head (14) translatable in second and third directions defining a plane, wherein the first direction is not parallel to the plane; and a device (40,44,46) for translating the maintenance head (14) in at least the second and third directions in the plane to engage the print head (12) at the cleaning station (36). In order to position the print head (12) and maintenance head (14) into proper mating relationship, the print head (12) is driven to a hard stop, an indicator of the distance from the proper mating position to the print head hard stop is measured, the print head distance indicator is stored in a memory, the maintenance head (14) is driven to a hard stop, an indicator of the distance from the proper mating position to the maintenance head hard stop is measured, and the maintenance head distance indicator is stored in the memory. The print head distance indicator is then used to repeatably return the print head (12) to the proper mating relationship position, and the maintenance head distance indicator is used to repeatably return the maintenance head to the proper mating position. <IMAGE>
