    Hello,

    New trouble for me (bad karma).

    I already had this there was many many years, but didn't remember how to fix it.

    Linear encoder test is ok.

    Thank you for your help !

    Is this the same printer you have been posting about? - RF640 - Nozzle Check (Test Print) Serious trouble | Signs101.com: Largest Forum for Signmaking Professionals
    If so, you likely have a defective ribbon. Look for any ink residue around the connector area, examine the ribbon contacts closely for any damage and replace if in doubt. This type of test print usually indicates a color channel starts free firing due to control signal loss from a defective head ribbon. Also look for any leakage around the head.

    Hello,
    It's another Printer.

    I change ribbon from the head print same result.

    As you want can see on the Picture, the test print is OK in the middle but not at the right... Weird no ?

    I would suggest cleaning the encoder strip with acetone and a microfiber cloth. Let us know the results...

    Hello,

    I changed the ribbons from Mainboard to Headcarriadge board, and it's fine right now :)
