ABSTRACT:
In a thermal transfer printer, before a thermal head transfers an ink component of a yellow region on a recording paper, the thermal head is preheated up to a transfer temperature and by sublimating a black ink component constituting a mark pattern during preheating, records used information in the mark pattern. After turn-on of an electric power, when an optical sensor reads the used information, an ink ribbon driving mechanism is driven until the optical sensor detects the rear mark pattern in which the used information is not recorded to locate the start of an unused region of an ink ribbon. Thus, residual amount of the ink ribbon is grasped accurately and the start of the unused region is located accurately without increasing the costs of ink ribbon.
