Thank you Ken T, but this doesn't seem to work as it should. I have performed the steps as indicated (I used a half black and half white sheet of paper) but the camera still fails to autofocus. I have also tried resetting all settings to default, including any custom settings, assuming that the autofocus may have been adjusted accidentally when my wife was playing with it. Bear with my attempt at describing the situation but, I put the camera to face the black/white paper, utilized the center focus setting, centered the paper in the view (ensuring the contrast was in the center of the frame), and the autofocus very quickly makes the "whir-whir" sound of the autofocus a couple times when the shutter button is half pressed, sometimes even going into and out of focus, but never stops in focus (visual [not visually in focus] and digital confirmation [blinky focus light]). Not sure if this is helpful or not, but as an additional detail, it seems like the AF mechanism stays in a very tight band of its focusing range, as opposed to the amount of focusing "distance" I have manually (I apologize for the inability to speak in "camera", I'm a computer guy by trade, and though I think I can fall in love with photography, I am unfamiliar with it's lingo). I'm worried the camera is malfunctioning, I have not yet been able to utilize the AF feature of the camera successfully yet (due to the old lens issue in my first post, and what seems to be broken AF now). I live in Hawaii, and there is not a photo repair shop on Island, but I will be traveling to San Diego this weekend, is it possibly a camera malfunction? Is there an AF sensor I can clean?

Hello all,
Here's my long frustrating story. I purchased a k20d for my wife to upgrade her from film to digital. I was originally told the 300mm lens that I had purchased for her old camera would work on the new one. Long story short, none of the old camera's lenses AF worked with the new one. So we proceeded to purchase a new lens, the one in the title; Pentax SMC-DA 18-55mm. Now here is where the real frustration starts. On trying to get the autofocus to work on this lens, which is brand new, the auto-focus jumps back and forth but cannot focus (it gives up after a few seconds and shows the blinky focus indicator (meaning not focused). Any help here would be greatly appreciated. I have tried upgrading from 1.00 to 1.04, cleaning the connections. One thing to note, if i go to manual focus, focus the frame, and then set it to auto focus, it realizes that it is focused, and lets me take the picture. PLEASE HELP.
