Looks great! This is perfect for simply mounting the head on a motion axis.
Does the CIS have a name or order number? I could not find it on the ‘net.
Some of the signals on the head confuse me. I really don’t know what the 1v +-0.5V signal levels are good for. I have not seen that on other devices before and I don;t see the advantage over the 3V signals. OTOH, I have purposefully not printed with any of the four photo cartridges. Maybe these levels are just some idle noise and pin 11 to 15 are the shift register for the large black tank?!
