Abstract: A method of feeding solid ink sticks to a melting device in a phase change ink imaging device enables the solid ink sticks to move through the ink delivery system without buckling or being diverted from the feed path. The ink sticks fed to the ink delivery system have first and second contoured ends that complement the feed path to resist buckling due to feed forces and the bosses of one contoured end nest in the boss recesses of another contoured end of an adjacent ink stick to resist the effects of the feed forces as well.

Abstract: A solid ink printer includes a melt plate configured to melt solid ink. A heater is connected to the melt plate in order to raise the temperature of the melt plate. The temperature of the melt plate is detected by a temperature sensor that is provided away from the surface of the melt plate but is configured to sense the temperature of the melt plate. A mount is positioned on the melt plate between the temperature sensor and the melt plate. The mount includes a mica layer and at least one polyimide film layer. The mount is arranged on the melt plate such that the mica layer of the mount may be adjacent to the melt plate and the polyimide film layer may be adjacent to the temperature sensor. A pressure sensitive adhesive may be used to connect the mount to the melt plate.

Abstract: A solid ink printer includes a solid ink transportation control system that helps ensure a continuous supply of solid ink to a melting device within a printer.

Abstract: A solid ink delivery system provides solid ink sticks to a melting device in a printer. The delivery system includes a guide for guiding the stick in a prescribed path. The guide defines an inlet for receiving the stick. The inlet provides unobstructed passage of the stick through the inlet. The guide also defines a channel having a first end and a second end. The first end extends from the inlet. The channel provides unobstructed passage of the stick through the channel. The channel is adapted to contain a plurality of sticks in the channel. The guide further defines an outlet extending from the second end of the channel. The outlet provides unobstructed passage of the stick through the channel. The outlet is positioned below the inlet whereby only gravity is used to advance the sticks from the inlet to the outlet.

Abstract: A solid ink stick adapted for use with solid ink printers is provided. The stick includes a body defining a longitudinal axis of the body. The body defines an external periphery of the body. The external periphery has a groove formed on the periphery. The groove extends in a direction generally along the longitudinal axis of the body and at least a portion of the groove length is non linear.

Abstract: An ink stick for use in solid ink printers is provided. The ink stick is for use in a solid ink delivery system for delivering ink to a melting unit to melt the solid ink. The ink stick has opposed first and second stick external surfaces. At least one of the first and second stick external surfaces is arcuate.

Abstract: An ink stick for use in an ink delivery system of a phase change ink imaging device comprises an ink stick body having first and second opposed end surfaces and first and second opposed lateral side surfaces. The ink stick body is rotationally symmetric about a vertical central axis of the ink stick body. The ink stick body includes an interlocking face on the first end surface and a complementarily shaped interlocking face on the second end surface. A key is on each of the first and second side surfaces. The keys of the first and second side surfaces are similarly shaped. The key on the first side surface and the key on the second side surface are rotationally symmetrically positioned with respect to each other about the vertical central axis.
