3.5.9Head Voltage

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

3.5.10Peak 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):

IP=

N ⋅ VP

RH

 

IP: Peak current (A)

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

VP: Head drive voltage (V)

RH: Head resistance (Ω)
