摘要:
A media cassette adapted to hold multiple media types and an imaging apparatus which includes the media cassette. The media cassette includes a device for identifying the type of media loaded in the cassette to permit an adjustment of printer electronics based on the identified media in the cassette. The cassette comprises a cover that includes a section that is adapted to identify a a type of media. The identifying section can include a reflective surface or label which cooperates with a sensor in the imaging apparatus to detect and/or not detect light that is reflected back to the sensor. This signal is then used by the imaging apparatus to identify the type of media in the cassette, and adjust imaging operations based on the type of media in the cassette.

A thermal printer capable of preventing crease formation in a dye transfer area of a dye donor web that can cause a line artifact to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver, includes a print head having a bead of selectively heated resistive elements that make contact across the dye transfer area of the dye donor web and opposite edge areas of the dye donor web that are alongside the dye transfer area as the dye transfer area and the edge areas are progressively advanced under a longitudinal tension over the bead of resistive elements. Also, a control is adapted to selectively heat those resistive elements that make contact with the dye transfer area to effect a dye transfer from the dye transfer area to a dye receiver, and adapted to variably heat those resistive elements that make contact with the edge areas alongside the dye transfer area to effect a gradual drop in heat substantially from respective boundaries between the dye transfer area and the edge areas to an outer edge of each edge area that is spaced from the dye transfer area. As a result, when the heated transfer area and edge areas are subjected to a longitudinal tension, a relative resistance to being stretched will steadily increase towards each outer edge to maintain strength at each outer edge, but to avoid a sharp transition at the boundaries in order to prevent crease formation that can cause a line artifact.

A thermal printer is adapted to prevent crease formation in successive dye transfer areas of a dye donor web that can cause line artifacts to be printed on a dye receiver during dye transfer from each dye transfer area to the dye receiver in a dye transfer printer.

A method of reducing uneven use of the total number of printing elements on a print head in a printer, when selectively using the printing elements to make different size color image prints on respective similar size receiver mediums, comprises: selectively using the total number of printing elements to make color image prints substantially the same size as the receiver mediums; and selectively using a particular number of printing elements less than the total number of printing elements to make similar size color image prints smaller than the receiver mediums, but alternating which ones of the total number of printing elements can be selectively used to make each print so that the placement of each print on a receiver medium is alternated, whereby, since those printing elements that can be selectively used to make each print smaller than a receiver medium are alternated, uneven use of the printing elements is reduced.

摘要:
A method of reducing uneven use of a series of heating elements on a print head in a thermal printer comprises: selectively using certain ones of the heating elements to effect yellow, magenta and cyan dye transfers superimposed on a dye receiver medium to create a color image print smaller than the size of the receiver medium and leave a non-image non-color margin area along at least one side of the color image print; and using other ones of the heating elements to effect yellow, magenta and cyan dye transfers superimposed on a non-image non-color margin area left along at least one side of the color image print to make the margin area a shade of substantially gray or black, whereby, since those heating elements which are not to be selectively used to effect the dye transfers to create the color image print are instead used to effect the dye transfers to make a non-image non-color margin area left along at least one side of the color image print a shade of substantially gray or black, uneven use of the heating elements on the print head is reduced.
