ABSTRACT:
An improved ink stick supply assembly is provided for a solid ink color printer which reliability feeds solid ink sticks from an ink stick loading bin to ink stick melt plates which melt the ink sticks on demand and guide the molten ink into individual color ink reservoirs in the printer print head. Low ink and empty ink level sensors are provided which advise the printer operator when to replenish the ink stick supply. A low friction material and spring loaded pusher blocks facilitate travel of the inks through the ink stick feed chutes to the melt plates.
