VIII.4 Operation Description

Note:
Please read descriptions carefully for ink supply system, cleaning system and Ink
Control system before starting the following operations.
1. As soon as the printer's connected with power, system detects floating switch signal automatically,
and then ink will be filled into Sub-tank.
2. When ink channel lacks of ink, system will start the pump automatically; and indicator lighten. After
the floating switch senses the ink, the pump will continue to work for a little period and then stop; and
the indicator light extinguishes.
3. When ink in sub-tanks is used out or other reasons cause some pump running overtime, the system
will alarm (voice a straight buzz) and force to stop the pump automatically. Press "restore" button on
cleaning operation board to cancel the alarm, and system goes back to auto-ink-supply process.
4. When safety tank is full, system will alarm as short buzz.

VIII.5 Intelligent Detection Function

Intelligent detection function for ink supply system is implemented by collecting floating switch signal with
high frequency. By using concept of probability, the signal is regarded as effective if probability of floating
switch signals is higher than a set value (for example, 80%). Therefore, wrong act of floating switch can
affect the system's stability much less and accordingly system's anti-disturbance improves.
