Abstract
A print head has a print roller carrying one or more type holders thereon for imprinting a work piece movable between the print roller and a support roller, and has dual hot ink rollers carried on an ink roller support member which is movable so as to simultaneously engage one of the ink rollers with the printer roller for inking the type thereon and to move the other ink roller to a position away from the printer roller permitting replacement of the ink roller without stopping the printing operation. The support member carrying the dual ink rollers may be manually movable or may be movable by a hydraulically actuated rack and pinion or by an air cylinder. The printer roller may be equipped with a counter for providing a signal after a specified number of revolutions indicating a change of inking rollers is necessary. In the automatic embodiments, the counter may be connected to a control unit for automatically moving the support member to engage a fresh inking roller.
