Bi-directional printing suddenly stops

[force-ultimate]

Hi there, we're running a Mimaki JV33 with a brand new configured Main PCB board. It prints well for a few meters and then suddenly the bi-directional printing drops out. See attached photos, the print should be dark green but you can see the print fading out as the ink is only laid down in one direction.

We've changed the slider board and the station assay + station cable. And have tried reuploading the parameters... same problem.

Anyone have any ideas? Thanks in advance.

No photos attached that I can see.

This may or may not be helpful, but I had a similar thing happen on my Mutoh -- it ended up being a corrupt media profile. Deleted and recreated a new one (custom profile by the way, not from mgfr.) No problems since.

Sorry - messed that up. The dark green is the correct colour, you can see the head missing passes before ending up 100% uni-directional with a faded green print.

Thanks, good tip. We're using Caldera, I'll have a look at regenerating/reusing a profile.

FWIW I was also using Caldera when it happened.
