摘要:
A detector assembly for detecting registration marks on a printed sheet when different color printing on different colored sheets is present has a pair of light sources and a light sensor. The light sources are of different colors selected to be complimentary such that one light source or the other will be capable of detecting a substantial range of contrasting registration marks placed on sheets that can be of various colors. Controls are used for selecting the light source that provides an output sensed by a light sensor when passing over the registration marks.

A method of controlling a thermal print head having a plurality of resistive heaters to compensate for the effects of latent heat from the resistive heaters is disclosed. The plurality of resistive heaters are arranged in a line on a substrate with each of the plurality of resistive heaters corresponding to a pixel position on a medium such as paper. A compensation value is determined for each pixel in a line such that the effects of latent heat from the corresponding heater and from adjacent heaters are compensated. A compensated gray level for each pixel of the line is calculated as a function of a desired gray level for the particular pixel in the line and as a function of the associated compensation value. Finally, the heaters are driven as a function of the compensated gray levels to print the corresponding pixels of the line.

Identification card manufacturing security restricts use of an identification card manufacturing system with only authorized supplies. In accordance with one aspect of the invention, a supply-specific security code (SSSC) and supply-specific data are stored in memory of the supply. The SSSC is translated using the supply-specific data. Finally, the supply is authorized for use with the identification card manufacturing system only when the translated SSSC is found to be valid. In accordance with another aspect of the invention, an identification card manufacturing system is configured to operate only with supplies having corresponding customer-specific security codes (CSSC). A supply CSSC and supply-specific data are retrieved from memory of the supply. Additionally, a system CSSC and system-specific data are retrieved from memory of the identification card manufacturing system. The supply CSSC and the system CSSC are translated using the supply-specific data and the system-specific data, respectively. Finally, the supply is authorized for use with the identification card manufacturing system when the translated system CSSC and the translated supply CSSC correspond.

A printer includes a substrate input, a substrate transport, a printhead, a removable ribbon cartridge, a ribbon cartridge receiver, and a substrate output. The substrate transport is configured to feed a substrate from the substrate input along a print path. The printhead is positioned below the print path and is configured to print an image on a surface of the substrate. The ribbon cartridge is received in the ribbon cartridge receiver and contains a supply of print ribbon that extends between supply and take-up spools and over the printhead. The substrate can then be discharged through the substrate output.

The present invention relates to a protective film for application to a card member and forming identification cards having protective films. The method of applying protection to a card member includes providing a protective film. The protective film includes a protective overlay and an ink-receptive material. The ink-receptive material includes an ink-receptive coating on a backing layer. The ink-receptive coating is bonded to the protective overlay. The method also includes removing the backing layer from the ink-receptive coating and laminating the ink-receptive coating to a surface of a card member.

The present invention is directed to an identification card printer that can be used with a card cartridge that protects a stack of cards stored therein from environmental contamination and establishes a card transport plane, from which other components of the identification card printer can be aligned, independent of the card cartridge. The identification card printer includes a cartridge receiver adapted to receive the card cartridge and a card transport mechanism. The card transport mechanism includes a pair of feed rollers, portions of which extend to the cartridge receiver and define the card transport plane.

In a method of forming an identification card printer a sheet feed printer is provided having a printhead and a sheet feed mechanism that is driven by a sheet feed drive to feed paper sheets to the printhead for printing. Next, the sheet feed mechanism is replaced with a card transport mechanism that is used to feed cards from a card supply to the printhead for printing. The card transport mechanism is then linked to the sheet feed drive through a feed drive link. Finally, a master controller for controlling the operation of the card transport mechanism is installed. Additional aspects of the present invention relate to an identification card printer formed in accordance with the above-described method.

A roller support includes a body member, a bushing member, and a step member. The body member includes a first guide roller receiver that is adapted to receive an end of a first guide roller. The bushing member extends from a surface of the body member and has a central bore that extends through the body member. The step member is positioned adjacent the bushing member and extends from the surface of the body member in the direction of the bushing member.

An ink jet card printer is disclosed that includes an ink jet printhead and a transport mechanism. The ink jet printhead is adapted to print on portions of a surface of a card that are presented in a print position along a print path. The transport mechanism includes at least one cantilevering mechanism that is positioned to a side of the print position along the print path. The cantilevering mechanism is adapted to unobstructively present the surface of the card to the printhead in the print position.

A printer providing time coded heating energy applications to printhead resistors to provide variable volmetric densities. Variable densities can also be provided through integrating dithering with the varying of volumetric densities. The printer can provide either one of two kinds of printing technologies by selection.
