I was out sick on Friday, so just re-read your past posts to remember your situation.
Did you do any cleaning cycles after cleaning the print head? We don’t recommend using ammonia cleaners on the print head…
Are the vent holes open on your refillable carts for proper ink flow?
Have you shut down both your printer and computer, then restarted and tried printing a nozzle check?
Please let me know, thanks- Dana
