What should I do when an unusual nozzle test is printed?

It might be caused by something inside of inkjet nozzle. UV cured ink on the head surface or a media jam may clog the inkjet nozzles.

Do maintenance according to the following procedure. Please read the “Operation Manual” for more details.


  • Wiper Sponge Set (SPC-0578)
  • Ink Wiper Rubber Set (SPA-0168)
  • UJ Cleaning Swab (SPC-0386)
  • Nozzle Swab (SPC-0421)
  • Gloves
  • Goggles


  1. Check the subtank information, if subtank errors occur [e] is displayed.
    Execute [SUBTANK MAINTENANCE] to release the error.
  2. Do NORMAL CLEANING if something is wrong with nozzle test after (1)
  3. Do HARD CLEANING if something is wrong with nozzle test after (2)
  4. Do [WHITE MAINTE] when nozzle clogged only white
  5. Please check the ink remaining in the cartridge
    If there is not enough ink in the cartridge, replace it and do CLEANING again.
    Sometimes display shows there is enough remaining ink, but the actual ink cartridge is empty or very low.
    So please check the actual ink cartridge
  6. Wear goggles and gloves, and clean the side surface of the head and wiper with UJ cleaning swab
  7. Wet the nozzle swab with the cleaning solution, and clean the nozzle surface
  8. The reflection of the UV light becomes higher with wider head gap (more than 2.0mm).
    In this case, the adhered ink may cured or bond from UV light reflection.
    This causes nozzle deflection and nozzle clogging.
    Please refer to “Precaution when printing in head gap more than 2mm”
