7.5 Intelligent Detection Function
Intelligent detection function for ink supply system is implemented by collecting signal with high
frequency floating switch. By using concept of probability, we think the signal is useful if a signal of
floating switch is greater than a setting value (for example, 80%). Therefore, this reduces mistakes by
floating switch and improves ability for anti-interfere.
