A FRU assembly (10) comprises a melt chamber (20) including multiple subchambers (30) in which sticks of phase change ink (38, 40) are inserted and melted. Melted ink flows through apertures (54) to a reservoir (28) comprising multiple compartments (56). Each compartment contains a channel (90) and a siphon plate (114) that allow a siphon action that siphons melted ink in the compartments to an orifice (100) that leads to an ink jet print head (16). Heaters (52, 82, and 142) under the control of a CPU (154) melt the ink and keep the melted ink at a desired temperature during various modes of operation.
