Function test device for optical print head heaters in thermal bubble printers
A function test device for optical print head heaters in thermal bubble printers, which includes: a test end power supply to provide the power needed for the test device; a linear optical coupling device serially connected between a pulse power supply for driving a print head circuit and the print head heater to detect variation of a triggering current; and an amplification circuit to amplify an output signal of the linear optical coupling device and send the signal to a microprocessor.
