Abstract

PURPOSE:To eliminate variation of printing concentration easily generating during an exchange of a thermal print head by a method wherein a resistance value adjusting means is installed at a given position of a thermal print head assembly and supplying voltage or conduction time is made optimum. CONSTITUTION:A new thermal print head assembly 5 for exchange wherein a resistor 4 for adjustment is mounted on a print substrate connector 2 is connected to a stabilization power source unit 7. It is resulted in that R3 is connected in parallel to R1, accordingly, when this R3 is previously selected so that it may be optimum to a fixed resistor of a head 1, the optimum voltage is supplied to the head 1 and a printing effect by means of a new head can be adjusted in a same way as that before the exchange.
