HP 6310 All-in-One Printer - identify power connector

The power adapter for my HP 6310v "All-in-One" printer rubs against the cabinet when I slide the printer shelf in and out of my cabinet. I'd like to extend or replace the power cable that plugs into the back of the printer with a right-angle (90 degree) one, but I can't identify what type of connector it is. Can anyone help with this?

The power adapter with the connector attached is model# Q7211-60261. I just can't figure out a way to identify the connector. If anyone knows a good website to identify connectors, let me know and I'll have a look.

Here's some pics of the unidentified power connector...

I'd be willing to send a check for approx $10 to the first person to correctly help me identify this connector. This problem is becoming a grain of sand in my shoe... small, but very annoying.
