   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.
