Repairing and designing electronics for decades. I've rescued quite a few Epson, Canon, and HPs from terminal clogs.
I have an HP 3000cp 54 inch printer I need to unclog and get working. I've modded the cartridges to easily refill them. I know how to de-air HP print heads.
I've designed a constant pressure CIS before the Chinese patents, while everyone else was using just a bottle for the ink.
I have three Epson Stylus Color 3000 and two Epson 7600 waiting for me to unclog them. I'm putting pigmented ink in a CIS into an Epson R200 to use as a direct inkjet resist PCB printer.
