A toner cartridge according to one example embodiment includes a housing having a reservoir for holding toner. A first electrical contact and a second electrical contact are positioned on a first longitudinal end of the housing. The first electrical contact is electrically connected to processing circuitry positioned on the housing. The second electrical contact is electrically connected to an imaging component positioned on the housing. The first electrical contact is positioned higher than the second electrical contact. A first drive coupler and a second drive coupler are positioned on a second longitudinal end of the housing. The first electrical contact and the second electrical contact are positioned higher than a first rotational axis of the first drive coupler. The first electrical contact is positioned higher than a second rotational axis of the second drive coupler and the second electrical contact is positioned lower than the second rotational axis.
