What printer model cord have you being using since I have the same problem and wondering if someone has figure it out the dc pins. ThanksI do not have the DC power cord. I've been using a printer power cord onto the AC pins.
Don't know if it helps any, but the diagram of the "Sears 6" power socket over at Kens Electronics seems to agree with your pic.

I've been using one from a Canon printer. I think the printer was a M3600G. I don't recall the exact model number since it went to electronics recycling last summer after taking a short flight across the room.What printer model cord have you being using since I have the same problem and wondering if someone has figure it out the dc pins.

I can verify the AC pins are correct. The DC pins I haven't tried.
