Regardless of manufacturer, this frequently happens after cartridge replacement. On insertion of a new cartridge, a plastic seal on its base is punctured by a spike shaped duct in the base of the cartridge holder. Ink flows down through this duct into the print head where the printing process ejects it in tiny droplets through dozens of very fine nozzles using either piezoelectric or resistive transducers. More often than not, when you insert a new cartridge, a little bubble of air gets trapped in the duct and causes an airlock, preventing the ink from flowing freely to the print head. To flush out these airlocks after replacing a cartridge, the printer will usually automatically perform what is called an ink charging cycle. A single ink charging cycle is often insufficient to clear the airlock and when you try printing, you either get no printout or just a few lines and dots. The solution is to repeat the ink charging process and this can usually be forced by utilities built in to you
