3.6.7 Heat Storage Coefficient
In high speed printing, a difference in temperature arises between the rise in temperature of the thermal
head due to head activation and the temperature detected by the thermistor. Therefore, the activation
pulse must be corrected by simulating a rise in the temperature of the thermal head.
No correction is needed when the print ratio is low. When correction is not needed, set “1” as the heat
storage coefficient.
The heat storage coefficient is calculated as follows:
1)
Prepare the heat storage software counters to simulate heat storage.
(a)
Heat storage due to head activation
The heat storage counter counts up in each print period as follows.
T’=T+
T : Heat storage counter value
N :Number of the activated dots
(b)
Radiation
The heat storage counter value is multiplied by the radiation coefficient in each 2 msec.
T’=T
×
K
K : Radiation coefficient 0.996
2)
Calculate the heat storage coefficient with the following equation (9).
