After a recent damper replacement on my Epson Pro 11880, I am getting what I consider to be nozzle misfiring(s). This happens with good nozzle check patterns and without any apparent consistency. Sometime it strays into the border of a print and other times it ends at the edge of the printed image.
My first thought is an electrical issue...any thoughts on how to diagnose this? BTW - the damper was replaced by third party, which is what brings me to consider a ribbon was not reseated/reconnected properly.
