Black ink doesn't print. The ink cartridge is genuine HP and Is almost full. Printhead has been cleaned multiple times still won't print black. My colour ink bought at same time is working perfectly. Does anyone know how much it is to replace black ink printhead. The printer I bought was only £35.
The printhead on your printer model is integrated into the ink cartridge, so when you replace ink cartridge you have replaced a printhead.
If the printer was unused in the longer period ink inside ink cartridge gets dried and ink is not coming out from the nozzles, replace the ink cartridge with a new one and your printer will print fine again.
