Abstract
A cartridge for hot melt or phase change ink is tubular, having a cover at one end and an opening at the other end. Upon engagement and cooperation between the cartridge and a reservoir, solid ink is dropped under the influence of gravity through the opening in the cartridge. Solid ink is retained in the cartridge until such cooperation, which includes keying the cartridge to the reservoir and forming a seal of the inlet to the reservoir between the cartridge and the reservoir.
