Deskjet 3636 All in One Print Quality

HP DeskJet 3630 series [7902B1]
macOS 10.15 Catalina

Ordered and installed authentic HP cartridges and the print quality has been horrible ever since. Blacks just dont come properly. any reason why this could be happening? Have tried online support, cleaning the printer, printing test pages, aligning printer etc. None seems to be working. Pls help

@Hammad_Mumbai, Welcome to HP Support Community!


If you have already performed the steps from the document Fixing Poor Print Quality and the issue persists, it could be a hardware failure.


Please reach out to the HP Support in your region regarding the service options for your printer.


Hope this helps!
