Amazon.com Product Description:
Hobbyists and small offices will gain equal benefit from the HP Scanjet 4890. With non-optimized resolution of 4,800 x 9,600, 48-bit color, and 256-level grayscale, every image or text document comes out sharp and clear. The built-in adapter allows you to quickly produce sizable batch scans of 16 slides, 30 negatives, multiple medium format film frames, or a single 4" x 5" film negative, making short work of archiving old treasures or processing professional shots.

For bulky items, HP designed a lid that allows clean scans from a sleek scanner--with the lid in its normal position, the scanner measures just 4 inches tall. The scan bed is large enough to process standard 8" x 12" photos.

The 4890 has four front-panel buttons that give you one-touch access to copies or scanning directly to specific formats. Enlargement/reduction is available onscreen in a range of 10 to 2,000 percent in increments of one percent.

Compatible with both Macintosh and Windows operating systems, HP software includes features designed to improve yesterday's photos along with slides from your childhood--dust and scratch removal, color restore, brightening dark areas of a shot and red eye removal are all included. A hi-speed USB connection (cable included) is compatible with USB 2.0 ports and offers exceptionally fast data transfer--about 26 seconds for a single 4" x 6" photo and about 28 seconds for a text document to Word. HP includes a one-year warranty covering parts and labor and provides free telephone support.

Rating : - Get Something Else
I've had mine for about one year. Slide scanning: Unacceptable. B&W negative scanning: Unacceptable. Color neg scanning: passable. Print scanning: Excellent. Removing the glass for cleaning the underside: Nearly impossible. Software for Mac: Unacceptable. Scanning at high resolution: Unacceptable and not recommended by HP. Scanning documents as text: Unacceptable - you'll have to scan it as an image file.
If your medium goes into a TMA, the results will be inferior. I bought it specifically for slide scanning, and it is worthless for that.
