Abstract (en)
A print mechanism is described which has a constant current driven solenoid (22) acting against an arch-shaped hammer (10) to power the hammer (10) through an arc of powered flight followed by an arc of free flight. The solenoid/hammer engagement point (24) removes the solenoid to a position which does not obstruct print line visibility and the hammer (10) rest position is withdrawn to improve print line visibility.
