7900 Fatal code 1A39

It’s probably a short related to the cable connecting to the print-head being jostled and miss-aligned by head-strikes or something else that could do that.


This came up during a nozzle check. I did a black ink swap on the control panel that didn’t seem to work. I understand this is printhead related but maybe just a short? I’ve unplugged, swapped carts, you name it. I fee comfortable getting the screwdriver out if that’s what it takes and am open to suggestions.

So, removing the head and reseating cables might fix it?

Thanks for your help,

Possible it will fix it.

It’s never a sure bet with this model.
