The ink is also corrosive. It can corrode the metal faceplate

If you ever have a Thinkjet with missing dots, that's what has

I do! One of them with a missing row of dots,
and there was ink caked all over the contacts, and when I cleaned it, it seemed the
contacts had been eaten away. That explains it! Fortunately I have a spare one for spare
parts. Thanks Tony.
