Whew. 4 hours on this today. Head alignment; cartridge fills; power cleaning… nothing works.
I’m getting a faint, fuzzy, horizontal banding, particularly visible in solid shades of medium gray. The bands are about 1 headwidth apart, as if one ink is not being applied. But why the banding if there’s a channel failure?
Automatic nozzle check shows no missing blocks. And, no: it’s not in the image.
