Default Spectra 3000 - white ink firing randomly

Hi all!
Some of the white ink channels randomly spray after a few shirts. Even if we print in CMYK only, there is a white spray all around.
This is what happens when we do nozzle checks. (picture below)
Any ideas?

Hello and good morning!

This could be quite tricky. Need more information to get to the core of the issue. The usual questions would be:
- Environmental conditions, ok? (humidity/temperature)
- New printhead?
- Old printhead, cleaned?
- Testing new waveforms?

DTG Merch,
thank you for responding.

-Humidity is ok, but temperature a bit hot, above 80F
-Printhead is new, a couple of days old. When we just installed the printhead, we did have a problem with one of the cartridges not being recognized for several hours. We finally got it to work after hours of manipulations.
Another thing we've noticed, when we leave the printhead soaking overnight, it prints a few shirts normally, then white ink starts spraying again.
-Not sure what you mean by "Testing new waveforms"

change all these cables (to the print head) then you would be fine.
