  • Page 2: Safety Precautions

    SAFETY PRECAUTIONS ● Before using the printer, thoroughly read the following safety precautions for optimum printer use. ● 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 a hazardous situations that may arise if you ignore the precautions and perform an incorrect handling or operating...
  • Page 3 SAFETY PRECAUTIONS (Continued) 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. Arcs may be generated from open-type relays, switches, and brush motors.
  • Page 4 Read and understand the appropriate Material Safety Data Sheet (MSDS) before using any ink or makeup. ● Use Hitachi approved consumables and periodic replacement parts. Using products that are not designated by Hitachi could cause s failure in certain functions. ● Warning for Mercury -- THE LAMP IN THIS PRODUCT CONTAINS MERCURY.
  • Page 5 SAFETY PRECAUTIONS (Continued) 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 (Continued) 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.

    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 14 (9) When installing the print head and print head cable, comply with the following conditions. 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. When positioning the end of the print head below 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 m.
  • Page 15 (14) If you try to fix the print head with a magnetic substance (such as iron), the cover switch will malfunction resulting in an "Cover Open" error. This, you must only use nonmagnetic resins or metals for fixing the print head. (15) In the case of carrying the printer proper, use the handles in the drawing below.

  • Page 16: 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.
