Ink Loading: Ink Supply from Ink Tanks to Sub Tanks
In order to supply ink from Ink Tank to Sub Tank, Bubble Removing Valve is opened first.
Suction Pump generates negative pressure in the ink passage between the buffer section and Sub Tank
and the ink passage between Sub Tank and Ink Tank. Thus feeding ink to Sub Tank. When the
predetermined amount of ink is poured in Sub Tank, Bubble Removing Valve is closed. Air flows into Ink
Tank through Hollow Needle (atmosphere side), thus maintaining the pressure in Ink Tank constant.
This operation is performed for individual colors in order Bk, C, M, Y.
Open/closed states of valves, the operation state of Suction Pump, and the capping state of Printhead
are shown below.
