  • Page 24: Mechanical Operation

    2.2 MECHANICAL OPERATION 2.2.01 The Printhead Mechanism The Microline 395 uses a highly efficient stored energy type printhead. Power is not consumed until the printwires are activated, thereby extending the printhead life to approximately 200 million characters. The printhead uses 24 printwires (two columns of 12 wires each). Each wire is welded to an armature.
