Abstract
An apparatus and method disclosed for delivering solid-ink pellets in an image-forming device comprises a hopper that houses solid-ink pellets. The hopper defines a vent and is provided with a mechanism to regulate the passage of the solid-ink pellets through the vent. A restrainer member configured to receive the solid-ink pellets defines a restrainer surface and a spreading arrangement to evenly spread the solid-ink pellets on its surface. Positioned below the vent, the restrainer retains the solid-ink pellets and is configured to transmit heat to solid-ink pellets causing them to melt evenly.
Claims7
A system for delivering solid-ink pellets in an image forming device, the system comprising:
- a hopper for retaining solid-ink pellets, the hopper having inwardly sloped sides defining a vent between their closest edges for passage of solid-ink pellets therefrom;
- a rotary vane, disposed in the vent, including a spindle comprised of multiple vanes, space between adjacent vanes being sized to accept the solid-ink pellets;
- a roll restrainer disposed beneath the hopper vent, having a first surface and a second surface, the first surface including spreading members, and the second surface heated to a temperature sufficient to melt the solid-ink pellets disposed on the first surface;
- and
- a spreader baffle slantingly disposed between the hopper vent and the roll restrainer, having a first edge and a second edge such that the first edge is fixed to one of the sloped sides of the hopper and the second edge is suspended above the roll restrainer.
