Abstract
A dot matrix print head has a heat sink substantially surrounding the head for dissipating heat therefrom. A print head carriage includes a pivot or bearing assembly on one side of the print head and includes a bail type clamp pivoted on the carriage on the other side of the print head. The arrangement allows the heat sink to swing from a covered print head operating position to an uncovered position for servicing or for removing the print head.
