Pump encoder sensor
The pump encoder is a photo-interruptive type sensor. It reads the slits on the pump motor's encoder film to
control the amount of pump motor rotation.

Valve open/closed detection sensor
The photo-interrupter-type valve open/closed detection sensor detects the valve cam state.
When the link that operates in conjunction with the valve cam shields light, this sensor detects that the ink supply
valve has been opened.
Ink detection sensor
Presence of absence of ink in the ink tank is detected according to whether the two hollow needles are
electrically connected.
When the ink level in the ink tank lowers below the wall around the hollow needle at the air passage, this hollow
needle is electrically disconnected form the hollow needle located on the ink supply side, thus detecting that the
printer has run out of ink.
