I have an Epson 4800 printer that has started printing 4 fine lines across the page. The lines seem to be only printed by the printhead in the outbound direction. A nozzle check shows a perfect print pattern, as does a head alignment. I have cleaned the heads, and done a power cleaning.. but the lines are still the same.
On images with fine detail I get more lines than status and test prints from the Epson. On a Nozzle check I get just 4, 3 black and 1 blue. The line is about 1 pixel wide. This happens on multiple types of paper.
Any ideas? Anybody else seen this?
