PicoJet PJ-N256

INDUSTRIAL INK JET PRINTHEAD

  • Breakthrough Manufacturing Technology
  • Stainless Steel Design For Better Reliability
  • Low Cost Alternative
  • Maximized Ink Compatibility

The PicoJet PJ-N256 piezoelectric drop-on-demand printhead is the first robust all stainless steel ink jet printhead offered for use in the industrial printing industry. The PJ-N256 is manufactured using PicoJet’s patented intermetallic bonding process. This break through bonding technology allows PicoJet to join each of the printhead laminates together, including the orifice plate, using a metal welding process. The resulting bond makes for an amazingly robust, all metal printhead that eliminates the need for adhesives that can interact with ink chemistries.

The bend mode piezoelectric printhead design also eliminates ink contact with the piezoelectric ceramic material. By bonding the piezoceramic to a stainless steel diaphragm, ceramic contaminants are prevented from entering the fluid channels and causing nozzle blockage. This design also allows for the use of ink chemistries that were previously unavailable due to ink conductivity issues.

The PJ-N256 is also available in a complete eight printhead module configured to deliver four color printing at 300 dpi. The module eliminates the need for the majority of electronic integration by providing all the nozzle mapping and drive electronics necessary for printing. The PJ-M8-256 Module is easy to integrate and dramatically
