Little Tips 1. It'd better leave open the printer if you often use it, as most printers will start printhead cleaning automatically when reset, which will waste ink. 2. If the machine isn't used frequently, you can turn it off. Just need to switch on the power weekly, which will protect the printhead from clogging.
