    What SW are you using? Remember that when you change option in LE TE correction you need to do FCC. If you are using old SW there was a plugin for that.

    I'll check this morning, but for sure is old software (Orange screen)
    About the FCC I make all... in the Printcare I can select the hard/soft LE TE...but no change

    Seems that charge on the Pip was not constant...
