Honeywell Bull Italia S.p.a.

Franco Fattori

Control circuit for a dot matrix printing head of the permanent magnetic type or simple electromagnet type, wherein a printing element is subjected to a variable magnetic flux, owing to an energization current and/or to a movable armature movement, which causes an energization current to be established in the printing element for its actuation. The energization current is switched off for the deactivation of the printing element and which thereafter establishes a shorting path letting a current, induced in the printing element by mangetic flux changes due to the movable armature movement, to flow in the printing element, with a damping effect on the armature movement.
