Compact USB-powered flatbed scanner

The Ambir DS490-PRO is a slim flatbed scanner designed for desktop users who need occasional colour and monochrome digitisation of documents up to legal size. Its dual linear CMOS CIS sensor captures images at up to 600 dpi optical resolution with 48-bit colour depth and 8-bit greyscale depth. The unit draws power directly from a USB 2.0 port, which is also backward compatible with USB 1.1, so no external power supply is required.

Thermals noise and power draw

Because the scanner is entirely USB-powered, its power consumption stays within the limits of a standard USB 2.0 port and produces no measurable heat or fan noise during operation. Scanning a single-sided page at 200 dpi takes about seven seconds in monochrome mode, while duplex scanning requires roughly ten seconds per page. The low energy profile makes it suitable for continuous use on laptops or small-form-factor PCs without thermal concerns.

Build integration and space savings

Measuring 2.10 inches high, 2.60 inches wide and 12.20 inches long, the scanner occupies roughly the footprint of a three-hole punch and weighs 1.30 lbs, freeing valuable desk space compared with traditional flatbed units. It supports media up to 8.50 by 14.00 inches and 1.00 mm thick, covering letter and legal formats. The package includes AmbirScan Pro software on a CD for Windows 7, 8 and 10, and the device carries RoHS and WEEE environmental certifications.

Questions about this item

How do I install the DS490-PRO and which step do users often miss?

Connect the USB 2.0 cable to the computer, then run the AmbirScan Pro installer from the included CD before placing any documents on the glass.

What part of the DS490-PRO will need replacement first with regular use?

The dual linear CMOS CIS sensor and the feed rollers are the only moving or optical components; either may wear after heavy daily scanning.

What limit appears first when scanning continuously at 200 dpi?

The 7-second-per-page speed in mono mode and the 10-second duplex cycle set the throughput ceiling; the USB 2.0 bus does not bottleneck at this rate.
