  • Page 12: Ink Blockage Prevention

    A potential problem arises on shutdown when ink is left in the nozzle; as it is fast drying it will soon dry and clog up the nozzle. To overcome this, special procedures to clear the nozzle are necessary. With EC-JET printers the clean up procedures at shutdown are achieved by an automatic flushing system.

  • Page 13: Principles Of Operation

    Introduction Principles of Operation A conducting ink is supplied under pressure to an ink gun and forced EJ04 out through a small nozzle of typically 50 to 70 microns in diameter. As it passes through the nozzle the liquid is piezo-electrically pulsed (modulated) and the stream breaks up into a continuous series of drops which are equally spread and are of the same size.

  • Page 62: Troubleshooting

    Troubleshooting Introduction This section provides general advice on fault diagnosis on the EC-JET Ink Jet Printers, as well as specific procedures for identifying and rectifying faults. Fault diagnosis is complicated by the number of variables involved in producing good print quality. Fast, non-contact printing involves fluid dynamics, physics, electronics, computing and chemistry.

  • Page 63: Identifying Faults

    Troubleshooting Make use of the Diagnostics options to check and record the jet monitoring parameters of Pressure, Velocity Of Drop, Modulation and Phase. Compare these with the reference values and identify any out-of-specification measurements. (See “Diagnostics”) Make print samples (if possible) and examine the prints carefully for signs of print quality problems. - Only when all of the symptoms have been noted should an attempt be made to identify the possible cause of the problem.
