To avoid even in rotor-stator dispersion machines with high suction power that the drawn liquid is set into a rotational movement whereby the dispersion performance is impaired, the invention provides transitional elements, such as an intermediate piece, for establishing the connection between a rotor-stator dispersion machine and a container. In one embodiment, the cleaning composition is substantially free of alkyl phenol ethoxylates. The presenter has a home position adjacent to the printer document exit path.
