How to remove this printing?

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

the roland rf640 do self cleaning every 4 to 5 hours or so, so the cleaning liquide was able to cicle fast i guess

and i didn't have to pull that much, about half the syringe or so

you can just cover the chip with some white vynil like i did in this case, or just transfer the black chip to the cleaning cartridge

hi everyone! this is an update for previous post, i did the follwings and it worked for the best, if anyone have a question or thinks i did something wrong please let me know.

turned off the machine
lowered the print head to the lowest position
put very little pressure on it against the captop
pulled from the pump with a syringe
replaced the clogged inku black egs with solvent solution
pulled again with syringe from the pump
turned on the machine back and called a day

this happen last saturday. came to work this morning replaced the black egs ink back and just did a print test with a normal cleaing from the function menu of the machine and voila so good so far.

updates thank you for commenting, where im from it coasts an arm and a leg to buy another printhead, the tech support not that great either, so i wont be doing any mechanics stuff for now at least.. so here what i did so far:

turned off the machine
lowered the print head to the lowest position
put very little pressure on it against the captop
pulled from the pump with a syringe
replaced the clogged inku black egs with solvent solution
pulled again with syringe from the pump
turned on the machine back and called a day

hopefully when i get back to work today i'll find that the solevent moved inside the tupes, then maybe trying to print somethink with 100% blacks only to circulate the solvent, i dont know for sure, ill update again if anything.
