THERMAL HEAD
3.5.1
Structure of the Thermal Head
As shown in Figure 3-6, the thermal head of the printer consists of 384 heat elements, and head drivers
to drive the heat elements.
Serial printing data input from the DAT terminal is transferred to the shift register synchronously with the
CLK signal, then stored in the latch register with the timing of the LATCH signal.
Inputting the head activation signal (DST 1 to 6) activates heat elements in accordance with the printing
data stored in the latch register.
A maximum of six division printing is available for the printer.
Table 3-6 shows the relationship between DST signals and heat elements.
