Abstract
Each ink stick of a set of ink sticks for a phase change ink jet printer has formed on the top of the ink stick a three dimensional visually recognizable symbol. At least a portion of the visually recognizable symbol on each of the ink sticks is different, so that the printer user can distinguish which ink stick is intended for each of the ink feed channels of the ink jet printer.
Claims14
A set of ink sticks comprising:
- an ink stick, the ink stick comprising:
- an ink stick body having a plurality of surfaces, including a face surface;
- and
- a visually recognizable symbol formed on the face surface of the ink stick body;
- wherein the ink stick is adapted to be inserted in an insertion orientation into a feed channel of a phase change ink printer;
- wherein when the ink stick is in the insertion orientation, the face surface having the visually recognizable symbol is directed away from the feed channel;
- wherein when the ink stick is inserted in the insertion direction into the feed channel, the face surface having the symbol enters the feed channel last;
- wherein the visually recognizable symbol occupies less than a majority of the face surface;
- wherein the visually recognizable symbol has a dimension substantially perpendicular to the remainder of the face surface;
- wherein a majority of the shape of the visually recognizable symbol is not parallel to the edges of the face surface having the visually recognizable symbol;
- wherein the ink stick is adapted to move in a feed direction along the feed channel of the phase change ink jet printer;
- and
- wherein the feed direction is substantially perpendicular to the insertion direction;
- the set of ink sticks additionally comprising a second ink stick body having a plurality of surfaces, including a face surface, wherein:
- the second ink stick body has a visually recognizable symbol formed on the face surface of the second ink stick body;
- the second ink stick body is adapted to be inserted in an insertion orientation into a second feed channel of the phase change ink printer;
- when the second ink stick body is in the insertion orientation, the face surface having the second visually recognizable symbol is directed away from the second feed channel;
- the second visually recognizable symbol occupies less than a majority of the face surface of the second ink stick body;
- the second visually recognizable symbol has a dimension substantially perpendicular to the remainder of the face surface of the second ink stick body;
- and
- a majority of the shape of the second visually recognizable symbol is not parallel to the edges of the face surface having the second visually recognizable symbol.

A set of ink sticks for use in a solid ink feed system of a phase change ink jet printer, wherein the solid ink feed system has a plurality of feed channels, each feed channel identified with a different visually recognizable symbol, the set of ink sticks comprising:
- a plurality of ink sticks;
- wherein each of the ink sticks comprises:
- an ink stick body having a plurality of surfaces, including a face surface;
- and
- a visually recognizable symbol embossed on the face surface of the ink stick body;
- wherein the ink stick body is adapted to fit into one of the feed channels so that the face surface is last to enter the feed channel;
- wherein the visually recognizable symbol corresponds to one of the visually recognizable symbols that identifies one of the feed channels;
- and
- wherein the visually recognizable symbol embossed on the face surface encompasses less than a majority of the face surface;
- wherein at least a portion of each of the ink stick visually recognizable symbols has a dimension perpendicular to another portion of the face surface;
- and
- wherein a first one of the ink sticks has a first visually recognizable symbol embossed on the face surface thereof;
- wherein a second one of the ink sticks has a second visually recognizable symbol embossed on the face surface thereof;
- wherein the second visually recognizable symbol is different from the first visually recognizable symbol;
- and
- wherein the first and second visually recognizable symbols form a pattern of symbols.

A set of ink sticks for use in a solid ink feed system of a phase change ink jet printer, wherein the solid ink feed system has a plurality of feed channels, each feed channel identified with a different visually recognizable symbol, the set of ink sticks comprising:
- a plurality of ink sticks, each comprising an ink stick body having a plurality of external surfaces;
- wherein:
- one of the external surfaces of each ink stick body is a face surface;
- each ink stick body is adapted to fit in an insertion direction into one of the feed channels so that the face surface is last to enter the feed channel as the ink stick is inserted in the insertion direction into the feed channel;
- the face surface of each ink stick includes a symbol surface portion and a background surface portion;
- the symbol surface portion of each face surface has an elevation in the insertion direction relative to the background surface portion;
- the symbol surface portion of each face surface has a symbol surface area;
- the symbol surface portion of each face surface forms a visually recognizable symbol on the face surface;
- the symbol surface area of the symbol surface portion of the face surface is smaller than surface area of the background surface portion of the face surface;
- the visually recognizable symbol of each ink stick body corresponds to one of the visually recognizable symbols that identifies one of the feed channels;
- the symbol surface portion of the face surface of a first one of the ink sticks forms a first visually recognizable symbol;
- the symbol surface portion of the face surface of a second one of the ink sticks forms a second visually recognizable symbol;
- the second visually recognizable symbol is different from the first visually recognizable symbol;
- and
- the first and second visually recognizable symbols form a logical pattern of symbols.
