Kofax KF-7300 Image Capture Card ISA Bus Scanner Interface PC

Kofax KF-7300 Image Capture Card ISA Bus Scanner Interface PC

The Kofax KF-7300 is a full-length ISA bus image capture card designed to interface document scanners with PC-class computers. It connects to compatible Kofax document scanners via a DB50 (50-pin D-Sub) connector on the card bracket, allowing the host system to acquire scanned image data through the ISA expansion bus. The card's PCB is densely populated with processor, memory, and logic ICs supporting the image data transfer and buffering functions required for production document capture workflows.

Applications

Kofax was a leading provider of document capture and imaging technology throughout the 1990s and into the 2000s, and the KF-7300 was part of their line of hardware accelerator and scanner interface cards used in high-volume document scanning environments — financial institutions, insurance companies, government agencies, and records management operations. These ISA-bus capture cards allowed flatbed and ADF document scanners to connect directly to a PC workstation, offloading image processing from the host CPU to dedicated onboard logic. The ISA bus (Industry Standard Architecture) was the dominant PC expansion standard from the mid-1980s through the mid-1990s, making this a card suited to 286, 386, 486, and early Pentium-class AT-form-factor desktop systems running DOS or early Windows environments. Today the KF-7300 is primarily of interest to legacy Kofax system maintainers, document imaging historians, and collectors of 1990s-era PC expansion hardware.
