Horizontal bands across strips of one color only
If a printhead is faulty, you will see horizontal bands across strips of one color only; or at least the horizontal bands will be much more noticeable in one color than in the others.
NOTE Banding in the green strips is more difficult to see; and it may be caused by a yellow printhead or by a cyan printhead. If you see banding only in the green strip, it is caused by a yellow printhead; if you see banding in the green and cyan strips, it is caused by a cyan printhead.
