Ambir ImageScan Pro 490i Duplex Scanner

The Ambir ImageScan Pro 490i is a compact duplex document scanner designed for home and small-office users who need to digitise standard paperwork and ID cards. It captures both sides of a page in a single pass and connects via a single USB cable that also supplies power. The lightweight unit measures 2.10 by 2.60 by 12.20 inches and weighs 1.29 lbs.

USB 2.0 interface limits speed and OS support

The scanner uses a USB 2.0 connection that falls back to USB 1.1 speeds on older ports, so throughput is capped by that legacy interface. Driver support is listed for Windows 7, 8 and 10 only, leaving newer operating systems without guaranteed compatibility. Scan times vary with resolution and material, so the quoted rates are best-case figures.

600 dpi optical resolution defines image detail

The single specification that determines whether this scanner meets your needs is its maximum optical resolution of 600 dpi. This resolution governs the clarity of text and photo captures for archiving, ID verification or PDF creation. If your workflow demands higher detail, this model will not satisfy that requirement.

Questions about this item

Should I choose the DS490-AS model for both standard documents and ID cards?

Yes, the DS490-AS handles standard documents up to 8.5" x 14" and ID cards in full-color, grayscale or black-and-white, scanning both sides in one pass.

What does the 600 dpi optical resolution mean for my scanned files?

It captures fine text and photo detail on documents up to 8.5" x 14" so archived records, insurance cards or tax pages remain sharp and legible.

How does the USB 2.0 interface affect scanning speed and power?

The USB 2.0 cable supplies power and data, so no AC adapter is needed; simplex scans reach 7 seconds per page at 200 dpi while duplex runs at 10 seconds per page.
