Abstract
An inkjet printer for producing graphic or functional products, the inkjet printer having integrated optical monitoring of the correct function of each of the nozzles that shoot the ink onto the substrate. For this purpose, the drops ejected from the nozzles are illuminated from the direction of the ejecting nozzles, and the light reflected backwards from the drop flying away is conducted onto light-sensitive sensors during the flight of the drop.
