This block consists of Q208-216 and Q206, Q207. Q208-216 control each pin and Q206, Q207 control the
power supplied to the printhead.
The CPU (IC200) sends the printhead trigger pulses from terminal T04 to the Gate Array. During this time, the
head pin solenoids are fired by Q206-216 according to the data received from the Gate Array as H1-H9. IC205
and Q206, Q207 control the current used to drive the pin solenoids. A thermistor is attached in the printhead
and is used to detect overheating.
