Epson ET-4750 stuck in "Printer inspection mode" (Part 1)

[@TylerDeBoy]

I am in the exact same situation. I also tried to unclog my printhead. Mine went into a fax/dial troubleshoot mode, so I unplugged it for about 4 days. Now I am where you are, stuck in that “Set Jig” menu. When I tap the screen in “set jig” mode, it runs a test on the printhead then fails with “Ink Out ERROR” in red text. Bout ready to drop kick this thing

I have a solution video on my profile, go and watch it, contact the Ukrainian fellow from the video, he will reprogram it remotely and it will start fine again for just 15 USD. The problem of 4750 is that they are very fragile and hard to maintain machines, they clog very easily. And the problem of not printing could not be only clogged printhead, but also pump or dampers. I.e. even changing the printhead may not solve your problem. I have a ET 2720 it is different printhead and doesn't clog as easy as ET 4750 and it consumes much less ink. Unfortunately it has no duplex, but it prints faster.
