3.5.9 Head Voltage

The printer has a built-in head driver IC. Table 3-11 shows the head voltage.

Voltage Range

Head drive voltage V

21.6 to 26.4 V

Head logic voltage V

4.75 to 5.25 V

3.5.10 Peak Current

Since the peak current (maximum current) may reach the values calculated using equation (1) when

the thermal head is driven, make sure that the allowable current for the cable material and the voltage

drop on the cables are well within the specified range.

Equation (1):

: Peak current (A)

N: Number of dots that are driven at the same time

: Head drive voltage (V)

RH: Head resistance (Ω)

N × V
