Abstract: In some examples, an apparatus can include a supply reservoir including print substance, and a rotary valve having a central rotary axis, where the central rotary axis is perpendicular to a height of the supply reservoir, where the rotary valve is in a closed position such that the print substance is unable to be supplied from the supply reservoir.
