40496501TH Rev.1 36(2) Motion of Printhead (Fig.2-14)The armature usually looses the armature sprint with a permanent magnet, making it to beattracted by the core. In this time, the print wire integrated with the armature is also in resetstate, When the magnet coil is energized by a print command sent from the device controller,a magnetic flux will generate in the opposite direction against that of the permanent magnetand a restoring force of the armature in the opposite direction against the core, and then theprint wire impinge on the platen. There is a paper and ink ribbon between the platen and printwire, so this impinging motion allows the ink of ink ribbon to be transferred (printed) to thepaper.(i) When printing(ii) When not printingWire guide Armature assemblyThermistorCoilCoreMagnet assemblySpacerYokePrint wireWire guidePlatenPaperPlatenPaperFigure 2.21
