FY –33VC Operation manual
- 27 -
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 assistant 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 waste ink tank is full, system will alarm as intermission buzz. (Only one waste tank is
equipped, so this function is invalid at the moment)
5. When safety tank is full, system will alarm as short buzz.

8.5 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.
