Faint banding with a "clear" nozzle check prompted me to run a head alignment for the first time in about 1000 prints. Unidirectional and Bi-Directional auto alignments were run, per owners manual description. Subsequent nozzle checks show a single "area" of misalignment, confined to both cyan and vivid magenta channels, as shown in the attached image.
Faint banding persists sometimes, depending on content, in faintly colored regions. I am printing bidirectionally, meaning with High Speed on.
What do you make of the area of misalignment shown on the attached nozzle check? Might this cause banding? Does it signal a head problem, and can it be fixed with alignment procedures, perhaps Manual rather than Auto alignment?
