2.1.1.2 Printing Process
Figure 2-3 and Figure 2-4 show the normal state and ejecting state of the
printhead, respectively.
1. Normal State:
When the print signal is not output, PTZ also does not move from a waiting
state (normal state). (Refer to Figure 2-3.)
2) Ejecting State:
When the print signal is output from the C298MAIN board, IC (IR4C463S:
Nozzle Selector) located on the printhead unit latches data once by 1-byte
unit. An appropriate PZT latched by the nozzle selector is pushed into the
cavity by the common voltage applied from the main board. By this
operation, ink stored in the cavity spurts out from nozzles. (Refer to Figure
2-4.)
