sounds like you rushed in your troubleshooting process. image problems CAN be some of the easiest fixes there are.Originally Posted by karimharaka
Backgrond when copy or print or both?
Backgrond on color or B&W?
Backgrond has developer or not?
What's the color of backgrond?
From your small picture and incoherently description it's hard to help you.
A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
Blessed are they who can laugh at themselves, for they shall never cease to be amused.
I don't reply to private messages from end users.
I'm assuming by print dust he means background..Did you run the stabilzation, and gradation adjustments after replacing any of the items you mentioned? E
