GrafJet 128/64 Piezoceramic Print-head P371xxx






A piezoceramic print-head for EBS-1500 series printing systems. It contains a printing unit where nozzle valves are controlled with the application of piezoelectric transducers. No compressed air is required. The printing unit generates 64 pixels. Each single pixel is controlled separately and produced by 2 nozzles. The piezoceramic print-head has the following properties:
It is designed for making durable and legible prints on porous materials and reasonably smooth surfaces, such as cardboard and other paper packing, paper documents, fabrics, ceramic materials and building materials, leather, wood and timber, etc.,
It can be used for quality printing of alphanumerical and special characters on up to eight lines, of bar codes and a variety of graphics characters (logos) of the height of up to 22.9 mm,
It can run as part of single-head or multi-head systems under the control of general-purpose controllers UPC EBS-1501(2) or UPC EBS-1506,
The print-heads can work with 1500/20 series electromagnetic print-heads as part of a printing system controlled by the same controller,
It is equipped with a photo-detector holder which is installed on the right or left of the print-head according to the direction of object movement,
The print-heads can print with coloured inks, with each print-head using only one ink type,
Each print-head in the printing system is has its own ink supply system equipped with an ink-level indicator and empty-bottle signalling,
