How do I clean the printhead?
The printhead cleans itself automatically. If you wish to clean it manually in order to enhance the print quality, just press simultaneously on shift and cleaning. Sometimes cartridges are simply too clogged and there isn’t any way to clean them completely. Therefore, I don’t recommend cleaning the printhead directly using a wet cloth; I’ve tried it with a really dirty cartridge and it hasn’t changed anything. If you try it, you’re on your own.
