HITACHI  Printer
Thank you for purchasing the Hitachi IJ Printer Model UX Twin Nozzle.
This printer employs a noncontact, ink-jet method to print onto a print target.
This instruction manual describes the basic operating procedures, maintenance procedures, and other detailed
handling procedures of the Hitachi IJ Printer Model UX Twin Nozzle.
If the printer is improperly handled or maintained, it may not operate smoothly and may become defective or
cause an accident. It is therefore essential that you read this manual to gain a complete understanding of the
printer and use it correctly.
After thoroughly reading the manual, properly store it for future reference.

  • Page 1 HITACHI  Printer Model UX Twin-Nozzle Thank you for purchasing the Hitachi IJ Printer Model UX Twin Nozzle. This printer employs a noncontact, ink-jet method to print onto a print target. This instruction manual describes the basic operating procedures, maintenance procedures, and other detailed handling procedures of the Hitachi IJ Printer Model UX Twin Nozzle.
  • Page 2 SAFETY PRECAUTIONS ● You should observe the precautions set forth below in order to use the product properly and avoid endangering you or other persons or damaging property. For the purpose of clarifying the severity of injury or damage and likelihood of occurrence, the precautions are classified into two categories, WARNING and CAUTION, which both describe hazardous situations that may arise if you ignore the precautions and perform an incorrect handling or operating procedure.
  • Page 3 SAFETY PRECAUTIONS (Continued) Installation Environment of Printer WARNING ● Ensure that there is no flame- or arc-generating device around the printer. The ink and makeup are both flammable and may cause fire. Fire can be generated by matches, lighters, cigarettes, heaters, stoves, gas burners, welders, grinders and static electricity.
  • Page 4 SAFETY PRECAUTIONS (Continued) Grounding WARNING ● Ensure that all electrical wiring, connections and grounding comply with applicable cords. Properly connect the printer to its dedicated ground. Complete the above procedure to avoid electrical shock hazards. ● When welding, keep enough space between the IJ printer and the welding work area to prevent the arc from starting a fire.
  • Page 5 SAFETY PRECAUTIONS (Continued) Ink and Makeup Handling WARNING ● When charging a refill of ink or makeup, exchanging ink, or otherwise handling ink or makeup, take enough care not to spill ink or makeup. If you spill any ink or makeup by mistake, wipe it off neatly and promptly with wiping paper or something similar.
  • Page 6 CAUTION ● Only persons who have completed an operator training course for Hitachi IJP can operate and service the printer. If the printer is operated or serviced incorrectly, it may malfunction or break down. ● Do not attempt to make repairs for any purpose other than operation or maintenance.
  • Page 7 SAFETY PRECAUTIONS (Continued) Related Regulations WARNING ● Never drain the ink or makeup waste solution into a public sewer system. Waste disposal must comply with all appropriate regulations. Consult the appropriate regulatory agency for further information. ● The printer must be managed in compliance with all appropriate regulations. Read and understand the appropriate Safety Data Sheet (SDS) before using any ink or makeup.
  • Page 8 SAFETY PRECAUTIONS (Continued) WARNING <Keep all fire away.> ○ Ink and Makeup are flammable. ○ All fire must be kept away from the machine. ○ Spilled Ink and Makeup must be wiped off and dried up immediately. <Caution when handling Ink/Makeup> ○...

    2. INSTALLING PRECAUTIONS WARNING ● Ensure that there is no flame- or arc-generating device around the printer. The ink and makeup are both flammable and may cause fire. Fire can be generated by matches, lighters, cigarettes, heaters, stoves, gas burners, welders, grinders and static electricity.
  • Page 13 (9) When installing the print head and print head cable, comply with the following conditions or it will increase the risk of degraded performance of the ink supply and ink recovery behavior. When positioning the end of the print head above the printer main body installation surface,ensure that the distance between the end of the print head and the installation surface does not exceed 1.5 m.
  • Page 14 (13) When connecting an exhaust duct to the printer, install a damper and adjust the wind velocity at the intake port to 0.3 to 0.5 m/s. (Use an anemometer for verification. If the wind velocity is too high, the makeup consumption increases.) Connect a duct to this port (50 mm in diameter).

  • Page 15: Installation Check Items

    3. INSTALLATION CHECK ITEMS 3.1 Print head air purge If the makeup remains in the electrode section after cleaning or if you use the IJ printer at a high humidity, moisture condensation may occur within the print head, causing leakage from the deflection electrode section. It is also important to remember that dust or splashed ink accumulation on the deflection electrode section may cause leakage.
