An ink stick push block for use in a system for feeding solid ink sticks in a phase change printer, wherein each solid ink stick has an ink stick face surface having an ink stick face surface contour and an ink stick rear surface having a nonplanar ink stick rear surface contour, the ink stick push block. The push block includes an ink stick push block face having a nonplanar ink stick push block face contour, wherein at least a portion of the nonplanar ink stick push block face contour is the complement of at least a portion of the nonplanar ink stick rear surface contour.

A method and an apparatus for processing an image transparency entails the application of an intermediate transfer surface of a layer of sacrificial liquid to a supporting surface and the deposition of a phase change ink onto the liquid layer. The inked image is then contact transferred to an optically transmissive final receiving substrate, such as a plastic transparency.
摘要:
A printer having a paper printing mode and a transparency printing mode detects a leading edge portion of an image-receiving sheet. Based on detection of an opaque leading edge portion of a transparent sheet, the paper printing mode is disabled and a sheet size having boundaries is selected. The printer deposits ink on the transparent sheet within the boundaries of the selected sheet size.

A fixing and developing apparatus in which sheet material to be treated is passed through a high pressure nip defined by a pair of rollers. At least one of the rollers may have a composite construction. The composite roller includes an elongated tubular shell with a pressure applying external surface, an elongated core positioned within the tubular shell, and an elastomeric material disposed between the core and shell to support the shell on the core. The core may be of a number of configurations and may increase in transverse cross-sectional dimension from the respective ends of the core toward the center of the core. The core may taper continuously or in discrete steps from its center toward its first and second ends. In addition, the core may have a longitudinal cross-section with a crown in the shape of a beam deflection curve for a simply supported, uniformly constant cross-section beam. The shell may be similarly configured along its interior surface. Also, the elastomer may be compressed at the center of the roller relative to the ends of the roller to preload its center portion.

A method for producing a light-transmissive phase change ink printed substrate is described which comprises providing a substrate, and then printing on at least one surface of the substrate a predetermined pattern of a light-transmissive phase change ink which initially transmits light in a non-rectilinear path. The pattern of solidified phase change ink is then reoriented to form an ink layer of substantially uniform thickness. This ink layer will, in turn, produce an image which then will transmit light in a substantially rectilinear path.In one aspect of the invention, the substrate is light transmissive, and the reoriented printed substrate exhibits a high degree of lightness and chroma, and transmits light in a substantially rectilinear path. In this way, the reoriented printed substrate can be used in a projection device to project an image containing clear, saturated colors.
摘要:
A printer accurately controls the passage of print media therethrough and maintains the print media taut as the print media passes through a printing zone while the media is printed by an ink jet printer. The print media sheet is preferably carried by a rotating drum in a first direction through the printing zone, with the drum being reversed to cause the exiting of the print media sheet from the printer. A pressure fixing or fusing apparatus may be positioned to flatten ink spots on the print media as the print media exits from the printer. The pressure fixing or fusing mechanism is preferably used in the case of a hot-melt or phase-change ink jet printer.
摘要:
Methods and apparatus for processing printed substrates having a phase change ink layer of non-uniform thickness are disclosed. Application of a combination of heat and pressure reorients the printed ink layer to provide a layer having a substantially uniform thickness and flat surface conformation, at least in the area of each discrete color. A release surface (55) is positioned adjacent the printed ink layer during processing. A resilient contact surface (56) is also provided to facilitate reorientation of the printed ink layer. Mechanical buffing of the processed, printed substrate improves image quality. Application of a light transmissive, protective coating that overlays the printed ink layer also improves image quality.

Systems and methods are presented for generating consumable orders for document processing devices and for verifying approved source consumable usage in document processing devices, in which a customer computer receives electronic reports from the devices and from these ascertains whether particular devices will need replacement consumables and also whether non-program consumable products are being used in particular devices. If a replacement will be required, the customer computer presents a proposed order to the customer via prompting content customizable by a reseller. The customer can then accept, modify, or reject the proposed order, and any accepted or modified order is forwarded to an account manager system for automatic placement for consumable shipment from a manufacturer or distributor. If the device has a non-program consumable installed, the customer computer notifies the account manager system and may warn the customer that continued usage may void one or more warranty extensions or other program incentive.
