ABSTRACT:
A color thermal printer has a thermal head (18) for printing a full-color image in frame-sequential fashion to a color thermosensitive recording sheet (12), which includes at least yellow, magenta and cyan thermosensitive coloring layers (26-28) for developing yellow, magenta and cyan colors. Two transport rollers (22) nip and transport the recording sheet (12) while a thermal head (18) records to the recording sheet (12). At least one first fixing lamp (30, 70, 76) generates ultraviolet rays associated with the yellow coloring layer (28). At least one second fixing lamp (31, 71, 77) generates ultraviolet rays associated with the magenta coloring layer (27). The recording sheet (12) is fixed in a fixing station by the first and second fixing lamps (30, 31; 70, 71; 76, 77), which are supported by a fixer support device (35, 72, 74) in fashion selectively settable in the fixing station. The two fixing lamps (30, 31; 70, 71; 76, 77) are arrangeable substantially equally near to the two transport rollers (22) when set in the fixing station.
