Light Choke Cleaning Method

Perform this cleaning when printed colors are unstable or uneven, e.g., when color density is inconsistent, even if the same data is printed with the same settings. This will stabilize the output colors by agitating the ink.

IMPORTANT

Light choke cleaning consumes a lot of ink, and overly frequent use may damage the print heads themselves. Avoid performing this operation more than necessary.

Procedure
  1. If media has not been loaded, set it up.

  3. Tap Panel_Icon_Menu.
  4. Tap Maintenance - Light Choke Cleaning.
  5. Check for the group with dot drop-out or dot displacement by viewing the results of the printing test.
    The space from "A" to "B" is group A. The space from "B" to the right side is group B.


    MEMO

    If the printing-test results are difficult to interpret

    • Check the results in a bright location, changing your line of vision. They are visible using the reflection of the light.

    • Shine a black light on the printed media to check for the locations on which structural ink was printed. Depending on the media, these locations may be difficult to check. If it is difficult to see this ink, switch to a different media and perform the printing test again.
  6. Select the group of print heads to clean.

  10. Select Nozzle Drop-out Test and tap Execute.

    Perform a printing test again to check whether the dot drop-out and dot displacement have been corrected.

    MEMO

    • If the problem persists, try performing powerful cleaning again.

    • This cleaning can be effective when carried out periodically, according to the frequency of use.
