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.
