ABSTRACT:
An ink-jet printer for ink-jet printing onto a print media. The printer has an ink-jet cartridge for ejecting ink onto a print medium during printing operations. A rotating drum platen holds a print medium on an outer surface thereof, the drum platen having an interior volume defined therein and an end wall extending transversely to the outer surface. A carriage holds the cartridge in a closely arranged position relative to the external surface of the drum. A drum drive apparatus rotates the drum to move the print medium in relation to the printhead of the cartridge. The printer further has a printer controller mounted in a fixed position relative to a printer chassis, and an electronic circuit disposed in the interior volume of the drum platen. A data communication link passes data between the printer controller and the electronic circuit. The data link includes a capacitor comprising a first capacitor ring structure mounted to the end wall concentric to an axis of rotation of the platen, and a second capacitor ring structure mounted in fixed relation to the drum platen adjacent the end surface and in close proximity to the first capacitor ring structure.
