Deactivation of empty tanks
The primary cartridges are the tanks where the ink is deposited, generally located at the rear of the machine, each tank can hold one liter of ink, which is equivalent to one bottle.
The primary cartridges have an alarm system that alerts the user when a tank has less than 30% ink.
When a tank is not used, it is necessary to block the sensor inside the tank so that it does not generate an alarm. To block, use a cloth or foam and place it below the sensor, blocking the movement of the sensor downwards, so you can keep the alarm for empty tanks deactivated.
