    Presentation Continuous deviated ink jet printing The printer head is supplied with pressurized ink. The ink arrives in a cannon (2) with a hole ("nozzle") (3) through which the ink is ejected to form a jet. The ink jet is modulated by a piezo-electric resonator (1) to form calibrated and equidistant droplets.

    Adjustment and replacement procedures Adjusting the jet in the gutter Special tools: - Cannon orientation tool, ring spanner. - Bifocal lens (eyeglass). - Head cleaning kit. - Protective goggles. - 1.5 mm Allen wrench. - Tweezers. IMPORTANT Protective goggles must be worn during this operation to avoid any ink being splashed into your eyes.
  • Page 113 Adjustment and replacement procedures 6- Loosen the cannon holder lock screws (see Figure 1). 7- Bring the jet closer to point A or point A’ by pivoting the cannon in the cannon holder using an orientation tool at the top (Figure 2). IMPORTANT Rotate in the direction shown on the diagram to avoid unscrewing the cannon nut.
  • Page 114 Adjustment and replacement procedures 8- Visually center the jet in the charge electrode using the lower cam (see Figure 3). IMPORTANT Do not force the cams. Loosen or tighten the lock screws to ease or restrict the movement of the cannon holder. 9- Center the jet in the gutter using the upper cam (Figure 4).
  • Page 115 Adjustment and replacement procedures FINAL OPERATIONS 11- Tighten the two cannon holder lock screws without forcing them. 12- Stop the jet. Clean the head and reconnect the resonator leads. Replace the protective cover. Close the head cover. 13- Start the jet and re-enable the "Recup. fault" check. 14- Check the break-off point and adjust if necessary.

  • Page 116: Adjusting The Pressure Motor Speed

    Adjustment and replacement procedures Adjusting the pressure motor speed Special tools: - Allen wrench. The speed of rotation of the motor primarily depends on the ink viscosity. The by-pass must not be adjusted unless the ink viscosity is correct, i.e. when the viscosity measured by the printer is within one second of the reference viscosity.
