d) Ink agitating
Ink will be agitated to prevent the element of the pigment ink from subsiding in the ink tank and the subtank.
The valve motor drive is transmitted to the agitation cam, the agitation fin in the subtank rotates and ink in the subtank will be agitated. In addition, ink in the ink
tank circulated by moving the piston under the needle(ink supply) up and down.
The operation timing is as following table.
*1: The agitating operation don't execute at the same time with the printing and cleaning operation until the agitation operation finishes.
When executing the printing or ink supply valve opening suction operation (such as Cleaning 1/15/17) after the agitation operation finishes, their
operations execute at the same time with the agitation operation.
Also, when executing the suction operation that open or close the ink supply valve (such as Cleaning 2/4/5/6) after the agitation operation finishes,
their operations execute by stopping the agitation operation, and then the agitation operation is executed again after finishing the suction operation.
*2: The agitation operation at turning ON the power executes at the same time with the initial operation.
