Abstract
A cartridge is provided with a supply housing having at least one exterior surface defining a supply area adapted to receive a donor ribbon of predetermined width and a take-up housing having a main wall that defines a take-up area for receiving donor ribbon of predetermined width. A take-up projection on the take-up housing and the main wall jointly define a take-up window therebetween through which donor ribbon passes into the take-up area. The take-up projection includes at least one tensioning feature so as to pre-load the take-up projection such that the take-up projection is inhibited from warping toward towards the main wall.

A cartridge comprising:
- a supply housing having at least one exterior surface defining a supply area adapted to receive a donor ribbon of predetermined width;
- a take-up housing having a main wall defining a take-up area for receiving donor ribbon of predetermined width;
- and
- a take-up projection on the take-up housing, said take-up projection and said main wall jointly defining a take-up window there between through which donor ribbon passes into the take-up area, the take-up projection including at least one tensioning feature so as to pre-load the take-up projection to inhibit the take-up projection from warping towards the main wall, said at least one tensioning feature being located at one end of the take-up projection.

- a take-up housing having a main wall defining a take-up area for receiving donor ribbon of predetermined width;
- and
- a take-up projection on the take-up housing, said take-up projection and said main wall jointly defining a take-up window there between through which donor ribbon passes into the take-up area, the take-up projection including at least one tensioning feature so as to pre-load the take-up projection to inhibit the take-up projection from warping towards the main wall;
- wherein:
- the take-up projection has two ends and extends in a direction transverse to the path, the take-up projection being longer than the width of received donor ribbon;
- and
- the at least one tensioning feature is positioned on the take-up projection between the lateral edges of received donor ribbon and the end of the take-up projection.

A cartridge comprising:
- a supply housing having at least one exterior surface defining a supply area adapted to receive a donor ribbon of predetermined width;
- a take-up housing defining a take-up area;
- a connecting portion between the supply housing and the take-up housing, said connecting portion providing a printing path for the donor ribbon from the supply area to the take-up area;
- and
- a main wall and a take-up projection extend between the take-up housing and the connecting portion to define a take-up window there between through which the donor ribbon passes from the connecting portion into the take-up area, the take-up projection including at least one tensioning feature so as to pre-load the take-up projection to inhibit the take-up projection from warping towards the main wall, said at least one tensioning feature being located at one end of the take-up projection.
