ABSTRACT:
A printing system includes a print head to deliver ink to an image receptor and at least one ink reservoir to deliver ink to the print head. Driving circuitry provides signals to the print head to control delivery of the ink and a flexible circuit interposed between the print head and the ink reservoirs connects the driving circuitry to the print head. The flexible circuit may include a heater to provide heat to the ink reservoirs. Alternatively, the flexible circuit may be replaced with a rigid substrate having a heater within its layers.
