HP Printhead Got Stuck Again - I Cannot Print Colors

I'm dealing with a printhead problem, and it's really making me feel quite powerless. In the past, I had to dispose of an HP printer because of the same issue, and that experience made me steer clear of the brand for quite a while. Despite my previous experiences, this specific model garnered significant acclaim, prompting me to reconsider HP. Regrettably, after just 1.5 years, I'm encountering the same problem once more. Despite the ink cartridges being full, there’s no color printing, and the printhead seems to be stuck. The warranty just expired, which adds to the frustration of the situation. I'm really unsure about my next steps. I believe my time and money have been squandered, and this ongoing issue has significantly undermined my trust in the brand.
