Abstract
The thermal transfer line printer is provided with tension roller position detection means having tension rollers, rotatable tension roller support frames that support the tension rollers rotatably and press the tension rollers toward an intermediate sheet, and a detector and a sensor for detecting a position of the tension rollers and is provided with a controller for controlling operation of an intermediate transfer sheet feeding motor that moves at least the intermediate transfer sheet, and the controller controls the intermediate transfer sheet feeding motor so as to position the detectors in a detection range of the sensors when the intermediate transfer sheet is moved.
