Abstract
A serial printer having a platen (5) and a carriage (4) having a printer head (6) with a plurality of aligned print needles close to the platen (5) for mosaic printing is disclosed. According to the present invention, an ink ribbon is in a detachable ribbon cartridge (3) under tension, and the printer head (6) has a smooth slope at the top of the head (5) that slopes towards the platen, thus, when the ribbon cartridge is put on the printer, the ink ribbon is temporarily twisted at the top of the slope on the head (6), and by swinging the printer head (5) a few times along the platen (6), the ink ribbon (1) at the top of the slope slides down along the slope into the narrow gap between the head (6) and the platen (6), and thus, the ink ribbon (1) is positioned in front of the print needles.
