Do you know why my solder paste sticks to the squeegee so much that it mis-prints and how can I prevent it from happening. I can only get about 3/4 prints before this happens.

Hi, Check to make sure your paste is not dried up, and it should roll across the stencil, not slide. Also, if your running in a cold environment, then that can stiffen up the paste, and it will still to the blades, and not roll over the stencil corr
