The seller has listed the item as being complete and in working order as per the eBay listing guidelines ;

"Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections"

The power supply is definitely not in the picture and it is useless without it. I have two scanners, one with a power supply and one without. I've not been able to track down a replacement power supply.

I will look into the availability of the power supply, as it would be good to have a spare. These scanners are awesome.
