Hp Officejet 4620 All in one doesn't print any black ink anymore

[Rob0011]

Hello,

A week ago i had a paper jam in my printer, which i fixed by pulling the paper out. however, a new problem appeared afterwards, namely: the printer doesn't print any black ink anymore. I tried to replace the cartridge and update the printer firmware to fix the problem, and when i changed the cartrigde, i saw that a puddle of black ink was laying on the filter where the cartridge makes contact with the printer. I think the printerhead might be clogged or so since the cartridge seems to provide the ink to the printer. My printer is already out of warranty and i wonder what i could do to fix the problem myself. Any help would be greatly appreciated. Apologies for any bad English, im Dutch.

Below you can find a picture of the cartridge holder and encircled in red the place where the puddle of black ink was(i cleaned it and then took the picture).

Suspect your printer has failed due to the paper jam, but you never know.  Let us know.

Search for more if needed.  If no joy, your printer is toast.

I tried to put some water drops on the mesh of the printercarriage(like of alot of the Youtube video's suggest), but like the ink it stayed on top of there. Because i was sure it was clogged, i used compressed air as last resort to clean the printerhead(dont/didnt know if it could damage the printer). And that seemed to work, afterwards a bit of water went trough the mesh and the printer seems to be working again now. Thanks for the advice.
