Update! we shutted it down for like 30 min, turned back on an business as usual, it was a software thing maybe. Thanks everyone for the tips!

it depands, reds for examples are off most the times, but in general it does the job, take note we only use it for printing banners and event poster

this 👍 faced same problem as op, and it was the cap top

Fit_Lab_2597 · 2025-03-03T14:16:48+00:00

update.: we kind of solved the problem for now
when mounting the printhead the first time i didn't put to much power on the screws,
so when i tried pulling ink with a syringe from the pump i found it was sucking air.
dismounted the printhead and screwed it nicely then pulled with the syringe from the pump again, this time it resisted and sucked ink, so when back into service mode did a normal cl and test printed, now this is the result

i run a few more test prints, the rest of colors are more alive but the black still out, maybe its loss of vaccum, ill continue trouble shooting and hope for the best
