  • It is not 24v at the ink head. The head needs around 20v @ ~300mA.

  • The other pis are pulled to ground to fire each nozzle. I strongly suggest re-reading pages 14-15 as they describe the voltage and timing for the head.

  • Pins 2
    amp; 7 have no connection to the head and are just connected together in the cable. They can be used for cable detection.

  • If you look at the circuit diagram there is a LM317 regulator between the 24v and the head. This is what regulates the 20v.
