CJV30, started it up and noticed one black channel completely out.
No worries, it'll come back with a clean or 2. Nope, nothing.
Swapped the cap top for a new one. Confirmed getting good suction.
Several hard cleans, lots of ink coming through but not one nozzle showing on that channel.
Swapped the 2 black dampers around, more cleans, still nothing.
I injected ink into that channel through the nipple. Ink went through because it contaminated the other colours. Still not one nozzle fired.
I figured it must be the head, so I swapped it for another head I have here which should be good.
I got all other channels working except for this same black channel, which is still 100% missing.
So, now I'm thinking it may be an electrical problem further up?
Slider board? I'm at a loss at this point...
