From my memory of inkjets there is a head priming task you do from the menu or with some button presses.
Takes 30 sec or so and sits there pumping ink through the head and out into the waste pad inside the machine.
Basically need to clear out all the air in the lines.

That only applies to printers with permanent printheads, where the cartridges are purely ink tanks. (And even then, I've never seen one where that had to be done manually.)

OP explicitly said theirs had cartridges with integrated heads, so priming is not applicable here because there are no lines at all.

We had to do a prime manually on occasionally for our old canon inkjet. Usually if you left it sitting for a year, or you put a new head in it.

In that case I dunno, maybe there is a power/data issue getting to the head.  Check the ribbon cable for damage and check the connectors.

Is your new print cartridge OEM or some china copy?

There's a suction cup where the printhead usually rests when it's not printing, and a peristaltic pump attached to it that sucks ink through the printhead for the cleaning cycle (and deposits it into a large absorbent pad). Is there any ink coming out when you do a cleaning cycle?
ThunderZed:
I thought it'd has been a bet to make this old combo HP print and I've been using it as scanner because I had got no one... a quite "cumbersome" one indeed! Due to that I just waited months to get a good deal buying this cheap compatible cartridge at my local Amazon when its cost went down under 10 euros.

I followed your tips (as I could understand them :)) and:
- I put a piece of adsorbing paper upon the black color's pad and I made some printing heads cleanings to check if black ink'd has drained out or not and the paper was clean after 3 cleanings attempts (see my attachments before VS after);
- by the way W10 system sw lets me do a cycle of 3 cleanings and the 2nd one is defines "mild" and the 3rd one is defined "cartridges priming" so we can do this sort of heads priming by windows system though it's not mentioned in HP user's guide so there's no way to do that pressing buttons nor by its proprietary sw because I can't install it on W10 as I said in my 1st post;
- I tried to print 5 times a quite colorful image but without success: still only blank pages.

Did I carry on my attempts properly based on your tips?
Is there anything else I could try before surrendering and using it only as a scanner?
Maybe it's a silly idea but what if I could drain out ink from the head by a sort of manual suctioning action? Anyway I'd rather not to suck it by my mouth :)

(20+ year user of Canon inkjets here.)

Head cleaning cycle, yes. But priming is something needed in printers where the ink receptacle is connected by hoses, so there’s distance. That isn’t the case here.

Printers that need to have their heads primed, mostly during initial setup, will do it on their own.
