Ok, there's a slot on my printer that I put my digi cam's memory card in and it recognizes it and a window pops up so I can up my pics onto my computer. Well just recently when I pop it in, it doesn't do shit.
Make sure its in all the way and jiggle it a little. If that doesn't work, then shut down your computer, turn the printer off, unplug the printer from the wall and the computer, then reconnect and restart.
