Abstract
An ink-jet printer head is composed of individual, stacked ink-jet printer modules operating according to the edge-shooter principle and equipped with plate-shaped piezoelectric actuators whose electrodes are contacted to leads of a ribbon conductor. The ink-jet printer head has a simplified structure and improved service properties and is composed of individual, identical ink-jet printer modules whose nozzle rows are arranged offset relative to one another and can be easily interchanged, because the carrier layer of the ribbon conductors enveloping the leads is reinforced and shaped in the region between neighboring ink-jet printer modules, so that the required spacing between the piezoactuators and between the nozzle rows of the ink-jet printer modules as well as an exact fixing thereof relative to one another are achieved. In this way, the ribbon conductors serve as a contact element, a spacer and an adjustment member for neighboring ink-jet printer modules. Complicated housing and front masks are thus eliminated and the number of components is reduced and adjustment outlay is largely avoided. The ink-jet printer head is provided for use in small, fast printers, wherein a large number of nozzles are required.
