All my ink cartridges are full but when I print the "black" ink will not print. Anyone out there ever had a similar problem and what did you do.1 person got this answerI do too

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.http://h30434.www3.hp.com/t5/Other-printing-questions/HP-K5300-not-printing-black/m-p/376191#M26084
