Abstract

PURPOSE:To remove an ink adhered to the tip of a needle and prevent discoloration in color printing, by using an ink ribbon having a plurality of colors, and cleaning the tips of needles of a printing head. CONSTITUTION:A controlling part 1 controls the entire part of a printer. Color changeover in color printing is performed by moving an ink ribbon cassette 3 upward or downward by a mechanism part 2 according to a signal from the controlling part 1. At the time of color changeover, the cassette 3 is not directly moved to a position for the next color. Namely, the cassette 3 is moved to a position for a cleaning tape layer 15 for cleaning needles of a printing head, the layer 15 is fed simultaneously with the ink ribbon, thereby removing an ink adhered to the tips of the needles, and then the cassette 3 is moved to a position for an ink ribbon layer of the next color under control.

く手段を有していなかった。Conventionally, dot-impact color printers that use ink ribbons of multiple colors have been controlled to print light colors first to prevent discoloration of the printed colors, and the printing of dark colors onto light ink ribbons has been controlled. This prevents the print color from changing due to transfer. However, there was no means for removing ink adhering to the tip of the print head.

Since there was no means to remove the ink adhering to the tip of the print head, the ink of the previously printed color adhering to the tip of the needle of the print head would adhere to the back side of the ink ribbon of the next color and gradually discolor. There was also a drawback that the printed text changed color.
