I've been using the printer moderately , max printed per month will be 3-4 times , each only printed around 5-10 page max. Before this problem, the colour wouldn't came out at all, and a technician told me there was air bubble in the ink line and because once the printed wasn't being used for about 2 month , and the printer was off . so I've been told to keep the printer in idle even im not using it for a while .
I've tried checkin the supplies status in hp utility, the results are tri colour ink empty, black in empty, but the ink tank outside were all still full.
