Ink ribbon preventing skip and heat transfer-printing image-forming device

Abstract

Provided is an ink ribbon and a heat transfer-printing image-forming device comprising the same. The ink ribbon includes a printing area having two or more printing portions to form images on the medium, wherein the printing area is repeatedly formed in a longitudinal direction, and two or more starting markers which indicate the start of new printing area are formed repeatedly. The heat transfer-printing image-forming device comprises: an ink ribbon, wherein a printing area with two or more printing portions is provided, and each leading end of the printing portion has two or more starting markers; an ink ribbon driving unit for driving the ink ribbon longitudinally; a starting marker sensing unit for detecting the starting marker; a printing unit for heating the ink according to the image data, and transporting the ink onto the medium; a medium driving unit for supplying or discharging the medium; and a controlling unit for controlling the ink ribbon driving unit, printing unit and medium driving unit for forming an image on the medium when the starting marker sensing unit has detected the starting marker.

Problems solved by technology

However, when an image forming device with a regular ink ribbon is initialized again, for example, when paper is supplied to the device, an ink ribbon cassette is replaced, or the power is turned on and off, the device detects the next start mark, so there is a possibility of skipping unused printing area, which leads to the problem of ink ribbon waste
