ABSTRACT:
A thermal transfer printer of this invention is provided with recording paper carrier rollers disposed on both the upstream side and the downstream side of the thermal transfer head along the paper carrying direction and, further, with a sensor for detecting as to whether or not the recording paper is present on the downstream side lower than the carrier roller disposed on the downstream side along the paper carrying direction. In setting the recording paper for the first time, initial position setting of the recording paper depends on detection of the arrival of the foremost end of the paper at the carrier roller on the downstream side and, when the sensor detects the absence of the paper in the backward carrying thereof after completing the printing with one color, control for stopping backward carrying is performed. Accordingly, in the printer of this invention, because of tight contact between the recording paper and the platen, a relative position of the thermal transfer head to the recording paper is constantly definite and a possibility that the recording paper slips off the carrier roller due to excessive rewinding is avoided.
