This can happen to printer ink cartridge with attached print heads such as HP, Lexmark or Dell. All cartridges are weighed and tested before leaving the factory so lack of ink isn't the problem. It usually has to do with the print head of the cartridge not having any ink to feed it. This happens because cartridges are kept flat or upside down for weeks or months before being used and the ink settles away from the print head. The easiest remedy is to open the box and stand the cartridge upright for a few minutes before using. Then get a damp paper towel, fold it into quarters and sit the cartridge print head down onto it. Hold the cartridge down to the damp paper towel for three minutes. This will help pull the ink out of the print heads, priming them and getting them ready to print. Finally, install the printer ink cartridge into your printer and print a few test pages.
