I am working on CIS system now, before I was filling the cartridges with MIS ink. The auto-reset thing is new that I did last weekend. I modified the printer head height now it can accept up to 80mils (~2mm) board thickness. On the pictures board thickness was 31mils FR4 ( 0.8mm).
Concerning alignment there was 2 problems for me
1- To be sure that printer is always starting at the same Y-axis
--- Open a slot on left side of tray and use slotted optical switch to detect it. I assembled this optical switch to the left rear side paper entry of the printer. I modified my paper emulator software to use this sensor signal.
2- Alignment with my CNC.
---Roughly estimate the position of the printed image on tray and put drilled PCB to this location and loosely fix it by Scotch.
---Cover PCB with transparency and securely fix the transparency by Scotch.
---Print your with via/holes unfilled image on transparency
---Now, using small PCB sticks align the holes of the PCB to the image on the transparency
---Remove transparency
---Reprint image with filled via/holes on PCB
