    Hello.

    Please help me.

    The lines appear and disappear. When I print at 1440 rarely appear.

    Thank you

    I`m sorry that I can´t help you but wanted to up this post (also because I have a similar problem).

    Does it appear on bi-directional also?
    Asking because mine does light marks on one-directional only, not on bi-dir.
    Only visible on blank areas.

    Maybe the printheads just are on the end of their lifespan.
