☀ Tips

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.

4. If the printer showed "cartridge damage", an updated firmware will fix this problem.

NOTE: If your printer already shows "one or more cartridges damaged information", after firmware updating, you need to remove the cartridges and then reinstall so let the printer recognize cartridges. Pls pay attention to take some tissues on hand when remove the ink from printer to avoid ink leaking from ink outlet hole.
