Suddenly I began getting bad print quality on some horizontal lines of my documents. It seems to be on lines with black color. At first it would happen on the third or fourth copy of the same document. As it hasprogressed, it is on any prining.
The test prints show white streaks . I swapped out cartridges, cleaned the printhead, but it doesn't get better, it's getting worse. Is there any user maintenance I can do, or do I need to take it to a shop?
Thanks.
