I just won an Epson V500 on eBay for $50. As I was paying for it, I read the fine print and noticed that it didn't have a power adapter, or USB cable. Not a big deal as I'm sure I can get the USB from Best Buy, and the driver/software I'm sure I can download from the Epson site.
My question is about the power supply. I know it's a 24v 1.5a output, and 100-240v input, but can you find these generically as well?
If you go on their website, you'll find the AC adapter is Epson part # 2124947, costs $39.30, and as of this posting, is backordered. You might be able to find it from other places as well now that you know the part # to look for. I don't have a V500, so I don't know what the dimensions of the plug are for finding a generic replacement. Note, if you don't already have one, you'll need to order the AC cord that plugs into the "brick" separately. Compass has them for about $5.
No affiliation with Compass other than being a happy customer.
Have you tried Epson support? When the power supply on for my V500 failed (out of the warranty period), they sold me a new one for 10 including postage. That was in the UK, but presumably Epson USA has a similar scheme and similar prices.
Second-hand stores often have a variety of power supplies. Make sure such supplies have the correct voltage, adequate current output, and the correct polarity and connector.
