Title: Control of printing head
Inventor: ARAI KENICHIRO
IPC: B41J2/30
Filed: 1988-10-27
Abstract: PURPOSE:To allow the highest performance to be maintained constantly without degradation of the performance of a printing head by changing the energization duty to the printing head based on the temperature variation rate and temperature of a thermal sensor. CONSTITUTION:The temperature T of a thermistor 105 is measured for selection between modes immediately before start of printing for each line. In this case, a temperature difference DELTAT from a temperature five lines ahead is calculated, and a mode in which the data is printed on the line based on the thermistor temperature T and the temperature difference DELTAT. For instance, if the temperature of the thermistor 105 right before start of printing is 90 deg.C and the temperature five lines ahead is 85 deg.C, the temperature difference DELTAT is 5 deg. at point P. Since the point P is located in the area of mode B, data should be printed on the line for printing in mode B. When selection is made from mode A to mode B, the temperature difference between a coil 102 and the thermistor 105 is small, if the duty is low as shown by the continuous printing of '&'. On the other hand, the temperature difference is large, if the duty is high as shown by the continuous printing of ' '. Therefore, if the temperature difference DELTAT is small, the thermistor temperature T is set so that it is high, and if the difference is large, the thermistor temperature is set so that it is low.
