The following may work: remove all the ink supplies. Remove the printhead and soak it for about 5 minutes in 0.5" of very hot water. Gently blot the printhead on a soft damp paper towel to remove the excess water, then replace in the printer and then reinstall the ink supplies.

You could clean the black ink cartridge. For this you need to remove the black ink cartridge which is present in the printer. In order to clean the laser or scanner block you could use a cotton swab as it would fully clean the dirt. You need to clean the grime and the dried ink present in the printer. This would remove all the hindrances which prevent the ink from flowing. Cleaning the printer heads would also help to solve the problem.

there are two cartridge one is the ink cartridge which can be found on the left side of the printer (in front)and the other one is the head cartridge that can be found on the right side if you will open the printer cover that is the carriage check it if the flip cover is lock properly then try to reinsert the head cartridge..

hardware malfunction call up hp at 1800 474 6836 and we will troubleshoot for you trust me it will help cauz there are so many things that we can do that this space im writing in is to small.eg: connect the printer directly to the wall jack.
unplug the power cable of the printer and wait for 30 secs before repluggin the printer.move the carriage(that holds the printheads,spraying part of your printer) with your hand and check if it moves id it does n't then its definitly a hardware problem with your printer but you will need to call in to hp for a total problem resolution.

please do a head cleaning.

if their cartridge worked and yours did not. buy a new cartridge.
