One scan showed obvious streaks along a side-apparently the result of light leaking in along the edge of the scanner cover, since they disappeared when we moved the photo to a different position. Surprisingly, the 4890 also had some problems with photographic prints, which don't need the same bit depth or level of resolution as film. On less challenging slides, the scanner did an acceptable job. On a particularly hard-to-scan slide, much of a dark tree line that was against a bright sky became a solid mass of black.
The 4890 also loses more detail in dark areas than the 8400F and 3490, which is another way to say that its dynamic range-the ability to distinguish subtle differences in shading from white to black-isn't as good as you'd expect for the claimed 48-bit color depth.
The output was blurry compared with the 2,400-ppi results from less-expensive models, notably the Epson Perfection 3490 Photo and 4490 Photo, as well as our Editors' Choice Canon, the CanoScan 8400F. On our standard 2,400-ppi slide test, it simply didn't deliver the level of detail it should have for the claimed resolution. Unfortunately for the 4890, quality, not speed, is the most important concern with photos, and that's where this scanner stubs its toe badly. Most flatbed scanners take over twice as long. For slides, this was also by far the fastest flatbed scanner we've seen-it took just 26 seconds, at 2,400 by 2,400 ppi, for one slide.

In our tests with 35mm slides, the software did an excellent job of finding each slide and scanning it into its own file. To scan, you simply remove the mat from the top cover to reveal the transparency adaptor, place the template on the flatbed, and put the film in the template. There are three included templates: one for up to 16 35mm slides, one for 5 strips of 35mm film, and one for 120 and 220 medium-format and 4- by 5-inch film. The 4890 makes the mechanics of scanning film-both positives (such as slides) and negatives-surprisingly easy. The flatbed can accept originals up to 8.5-by-12.25 inches. Accuracy was reasonably good, though: We got no errors reading Times New Roman text at 10 points and Arial text at 8. Choices include RTF and searchable PDF, which gives the package some (highly limited) document-management capability, although that, as well as OCR capabilities are limited by the lack of an automatic document feeder. To use the software's integrated optical character recognition (OCR), you only have to select a text format for the output file. You can easily change the settings for a given original as needed and can redefine the defaults for the future simply by making changes and marking a check box.

Start a scan from HP's Solution Center, and it will launch the Twain driver with appropriate settings for the type of scan you picked-a photographic print, document, or film. The other included software is also impressively easy.
