Systems and methods for monitoring and managing documents printed by an imaging device. A cooling and recirculation system recirculates a second part of the exhaust gas from the gas exhaust passage into the gas intake passage via a recirculation passage while cooling the second part of the exhaust gas. Embedded capacitors are vertically connected to vias or other conductive structures within the package. The determination of a need for a connection may be made by request from an application, or automatically determining that a connection does not exist and needs to be set up.
