problem with my epson PRO 4800
I have run an automatic headalingment without results.
The cyan lines are staying during eatch headmovement.
I am afread that there is a problem witch the printhead.
I know it uses a lot of ink, but have you tried a power clean?
PI have a 4800 sometimes I have a persistentproblem with one colour I crate an A4 page in PS (or whatever editor you use) and cover it with dots, small and large and lines mainly vertically drawn all in the colour that is causing the problem. The intention being to really get that nozzle working on and off very fast. It sometimes cures problem. It's worth a try, nothing to lose.
