Hewlett Packard C7671B ScanJet XPA transparency adapter *new*

C7671B ScanJet XPA Transparency Adapter is an accessory designed for select HP ScanJet scanners. It allows users to scan transparent media, such as slides, film negatives, and overhead projector transparencies, by providing an additional light source specifically tailored for such materials. This transparency adapter is an invaluable tool for anyone needing to digitize transparent media with precision and ease.

In a DIY spirit, this can be used for backlighting objects, for example, when tracing onto paper by placing the reference image between the paper and the backlight. It can also be utilized in photography as an even light source or, for example, in reverse-engineering circuit boards to try to examine the internal layers of a multilayer PCB (assuming the internal layers are not completely solid).

Features:

• Transparency Scanning:
  • Enables high-quality scanning of transparent materials, which standard flatbed scanners cannot capture effectively.
  • Suitable for slides, film negatives (35mm and larger formats), and overhead transparencies.
• Enhanced Light Source:
  • Includes a built-in backlight or illumination system optimized for transparent media, ensuring accurate color reproduction and sharp detail.
• Compatibility:
  • Designed to work seamlessly with specific HP ScanJet scanner models, enhancing their functionality.
  • Check the scanner’s documentation for compatibility with the C7671B model.
• Plug-and-Play design:
  • Easy to install and integrate with the scanner.

Applications:

• Photographers and designers:
  • Ideal for digitizing old photographs, slides, and film negatives for editing or archival purposes.
• Education and business:
  • Useful for scanning overhead transparencies for presentations or digitizing archival material.
• Home users:
  • Enables easy conversion of family film negatives and slides into digital formats.
• DIY users:
  • PCB reverse engineering
  • Drawing with backlight
  • Using this with photography (jewellery, macro photography and so on)
  • Lighted ad or picture frame

Technical specifications of the light:

• Mini-DIN connector pinout:
  • 1: +24VDC
  • 2: GND
  • 3: GND
  • 4: GND
• Light source:
  • 2x L-shaped CCFL (cold cathode fluorescent lamp)
• Operating voltage:
  • 24VDC (most likely; compatible scanners use a 24V power supply. At 12V, the light is far too dim. Inside, there is a 35V electrolytic capacitor. All this suggests a 24VDC operating voltage, but we cannot confirm this with absolute certainty.)
• Max current:
  • 625mA
• Illuminated area size:
  • 143x1163mm
• Perfect size of paper, which fits inside the raised corners:
  • 172x208mm
• Max width of media if you want to feed it through and in between of the raised corners:
  • 132mm or 168mm
• Compatible with the following HP Scanjet models:
  • 5100Cxi
  • 5200Cxi
  • 5300C
  • 6100C
  • 6200Cxi
  • 6300 Series
  • 6300C
  • 6300Cxi
  • 7400C
