The head driver is incorporated in the Head SA.
The head driver is incorporated in the Head SA.
When printing, pin 116 (HDVON) of IC11 (Custom IC) goes to "High" level, and DTR1 and
TR1 turn ON. Thus +24V is supplied to the thermal head (Head SA).

The print data is sent from the Custom IC (IC11) to the head driver to select the thermal
elements to be heated. The data is sent via HD1 to 3, HDSTB, HDCLK and HDLAT lines
(pins 110, 111, 113, 108, 115 and 107 of IC11).

According to the print data, the thermal head heats the thermal elements to print dots on
thermal transfer paper. The width of heating pulse will be changed according to the head
temperature to keep the printing density constant.
