Title: Driving method of thermal head
Inventor: AKAO AKIO
IPC: B41J2/35
Filed: 1987-11-20
Abstract: PURPOSE:To enable dispersion of printing density owing to dispersion of average resistance value to be automatically corrected, by driving a thermal head according to the average resistance value calculated by applying a driving current to a thermal head to an extent that printing is not performed after applying printing data for heating all heating resistors. CONSTITUTION:Prior to photoprinting, a voltage VL lower than a driving voltage VH of a head in normal photoprinting is impressed to all heating elements of a thermal head 10, and current flowing to the head at that time is calculated from a voltage VD between both ends of a detecting resistance 22. Driving conditions of the head are set based on the calculated results. Setting of the driving conditions of the head is performed by either of the head driving voltage or a head driving pulse width. When for instance, VD is high, current value VD/RD is high, i.e., it is meant that a resistance value of the head is small. The head driving voltage VH is set low. Since the head is driven by this head driving condition in photoprinting operation hereafter, optimum drive corresponding to the resistance value of the head becomes possible.
