VueScan works with the Epson Perfection 4990 on Windows, Mac OS X and Linux.
If VueScan isn't working with the Firewire cable, try a USB cable, try a different Firewire port or a different Firewire cable.
This scanner has an infrared lamp for scanning film. VueScan's 'Filter | Infrared clean' option can be used to remove dust spots from film scans. This is similar to (and we think better than) the ICE and FARE algorithms.
It scans with visible light in the first pass and with infrared light in the second pass.
Infrared cleaning works well with all types of color negative and color slide film, including Kodachrome. However, silver-based black/white film doesn't work with infrared cleaning because the silver particles look the same in visible light and infrared light.
If you're using Windows and you've installed a Epson driver, VueScan's built-in drivers won't conflict with this. If you haven't installed a Windows driver for this scanner, VueScan will automatically install a driver.
You can use this scanner on Mac OS X and Linux without installing any other software.
On Linux, you need to set up libusb device protections.
Epson sold this scanner in some countries as the GT-X800.
