Figure 5.3.20 Print head drive circuit
[
Print head drive circuit control]
The controller (MB91110) reads print data from SRAM.
The data is set on the FPGA print control circuit.
At this point, printing does not begin yet.
The MPU sets the excitation time (T1) and flyback absorption time (T2) in the FPGA.
The MPU outputs print timing signal TIMER1.
In synchronization with print timing signal TIMER1, excitation signal PDV1-24 is output from the print head driver to turn on
the print head drive transistor (SDH02).
