Emergency Measure) Cleaning the Print Head Surface

When dot drop-out or dot deflection is not improved even if cleaning is performed several times, you can clean the surface of the print heads as an emergency measure. The print head surface (nozzle surface) is a very delicate mechanism, so work must be performed carefully and cautiously.

This operation is an emergency measure. It may damage defect-free parts depending on the symptoms, worsening the symptoms. If you have any questions, contact your authorized dealer.

IMPORTANT
  • Be sure to use different cleaning sticks in the color ink section and the optimizer ink section. Using the same cleaning stick may lead to the optimizer ink and color ink mixing, resulting in ink hardening and discharge issues.
  • Do not touch the tips of the cleaning sticks with your hands. Skin oil affixing to the print head caps may lead to malfunctions.
  • Do not use cleaning liquid other than the included cleaning liquid.
  • If you add cleaning liquid while cleaning a given location, do not dip the cleaning stick into the cleaning liquid bottle. Instead, drip the cleaning liquid onto the cleaning stick.
