Your small-format printer will notify you when your ink is almost depleted, but keeping an eye on the LCD panel will help you know when new ink needs to be ordered so you don’t run out in the middle of a job. The same applies to your waste tank. The tank level on the LCD screen will count up rather than down for the maintenance tanks. If the tank gets full, you will not be able to print until it is fixed.
