Last week I received an MK-Red printhead for my Z3200 clause my present one was 2017. When I went in there to replace the one I had, which was working normally, but out of warranty, the printer kept rejecting the new head, asking me to open it back up and put in a good print head, over and over till I gave up.
It just would not work so I put my old one back in, which it accepted immediately, and went back to work. lots of prints no problem.
Although I have never had a single defective print head in 13 years with these heads, I returned it and got a free replacement.
Today I received another new head and it is doing the same exact thing! I looked down there and I don’t see any ink or anything unusual looking. I put my old head back in and once again it works perfectly.
Anybody have any idea what this could be other than two defective MK print heads? What a headache.
