Unless there is something wrong with the film advance, spacing problems or missing frames are likely to be the result of loading error.

When you load the camera, the large arrows on the film backing should line up with the red dot inside the camera, and the counter should be on "S". Then close the back, and advance to "1".

Do not push the shutter button to advance the counter past "S" until you close the back. If you do, you need to advance the counter all the way around back to "S" before loading the film and closing the back.
