  • Patent number: 6530655
    Abstract: A drip plate design is provided for a solid ink color printer which reliably directs on-demand ink flow and securely retains solidified ink. The drip plate design includes a combination of one or more sized and shaped cutouts and protrusions for anchoring a solidified ink stick when the printer is not in operation and protrusions that impede downward movement of independent portions of an ink stick so that they remain in contact with a heated melt plate long enough to substantially melt, thereby inhibiting the unchecked sliding off of large separated slivers and chunks of ink during melt and delivery.
