Ink leak check

An ink leak check is required when disconnecting the Ink Tube from the Print head. The judgment method of the ink leak check is described below.

Check Point / チェックポイント

Installing the Leak Check Jig is performed after ink filling is completed after parts replacement. For details on installing the leak check jig, refer to Installing the Leak Check Jig.
Leak check procedure
  1. Insert the PET chips (A) for the leak check into the clearance (B) in the figure below.
  2. Pull out the PET chips (A) for the leak check.
  3. Check the ink adherence state on the cloudy surface (B) of the PET chips (A) to determine whether or not there is an ink leak.
  • Judgment criterion of leak check
    Check whether or not ink is adhered at a position of 1 mm or more from the leading edge (C) of the cloudy surface (B) of the PET chips (A). (Consider the result to be a fail if any of the two PET chips (A) for the leak check does not pass the check.)
    • Pass (no ink leak)
      When ink adherence is less than 1 mm from the leading edge (C) of the PET chip (A)
    • Fail (ink leak)
      When ink adherence is 1 mm or more from the leading edge (C) of the PET chip (A)
Check Point / チェックポイント

If the result is determined to be a fail (ink leak), refer to Print Head and perform the ink check again.
