Where is your nozzle test
OK disregard my message - now I got it.
You need to fix that missing channel to get your proper test.
Check for air in the lines; damper; captop
Is the machine level
Is the head sitting squarely on the top
Try a powerful clean and then the nozzle test, if good then do the test
Which channel is missing? Not sure what I am looking for. Is it the clear tubes.
Chris your machine has 2 heads - 8 channels each.Your A side shows 8 channels, while your B side shows 6. You are missing a complete damper. Solve that and you will have the test print you are desiring.
