2.1.1.1.1 Printing Process
Following figures indicate the sectional drawing of normal state and ejecting state of the print head.
(1) Normal State:
When the print signal is not output, PTZ also does not move in the waiting state(normal state).
(2) Ejecting State:
When the print signal is output from the C206 main board, IC(IR2C72C:Nozzle Selector) located
on the Print head unit latches the data once by 1-byte unit. Appropriate PZT latched by nozzle
selector is pushed into the cavity by applying common voltage from the C206 main board.
By this operation, ink that is stored in the cavity pops out from nozzles.
