This technology works based on piezoelectric pulses. Voltage fed through piezoelectric crystals or ceramic chambers causes a change in the shape of the chambers. This causes the coloured ink to be pressed through the nozzles. After a drop of ink leaves the print head, a vacuum is created in its place for a moment. This causes more ink to be suctioned out of the lower positioned ink tank to refill the pool.
8L prints variable data on labels in a continuous run. The items to be printed, for example, individual labels, are stacked in the supply magazine. The device sorts automatically and prints exactly in the selected position. The codings are smudge-proof in seconds.
