To its credit, the unit performed well in the 4-by-5-inch grayscale (600-dpi) print test, thanks to accurate brightness and contrast and good rendering of details. When tested at default settings, it didn't perform as well in capturing the challenging geometric patterns and small text of our monochrome line art print test. In our image quality tests, however, the 4890 wasn't as impressive. Equally outstanding was the 4890's performance in our informal film scan tests, with the unit taking just 91 seconds to complete a 4800-dpi scan of a 35mm slide. Digitizing our 4-by-5-inch photos was equally quick: the 4890 barely needed 11 seconds to scan the color print at 100 dpi, and 18 seconds to scan the grayscale print at 600 dpi. Using its Hi-Speed USB 2.0 interface, the 4890 delivered full-page color and black-and-white documents in about 17 and 14 seconds respectively, which is lightning fast. But our tests also found that the 4890's overall image quality and scanning software left something to be desired. When it comes to speed, this dual-purpose flatbed stands head and shoulders above many other scanners we have reviewed. If you need to produce a large number of scans as quickly as possible - especially on a routine basis - the HP Scanjet 4890 Photo Scanner may be the right choice for you.
