Advantages - Premium Prints Print vivid color and rich black output consistently, delivering outstanding results. - Easy to Install; Please remove the orange protective cap carefully and then install it into the correct slot. 1. It would be better to leave open the printer if you often use it, as most printers will start printhead cleaning automatically when reset, which will waste the ink. 2. But 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. 3. If prints come with color fading, streak or broken lines, please try to clean the printer head and nozzle for a few times.
