I have a Benq scanner 5000 and have lost its power cable.Please tell me what adapter to buy! input = 220v
The power cable and adapter will probably be unique to the scanner. You'll have to order the right one from HP, or through a computer store. The USB cable should be standard. Most printers and scanners use a USB cable with a Type A connector (flat) on one end, and a Type B connector (squared-off) on the other end. They're easy to find at Staples, as well as at computer stores.
