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

What size paste roll do you have on your stencil? It should be about 1/2" in diameter. What type of paste are you using? I have found that certain Mfgrs have this problem with some of their formulations. What typoe of printer and what is your squ

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.

Are you changing heads because of pastes or just changing widths ? Changing the head w/o cleaning is fairly straight forward. (Actually it's Pretty easy.) We have two widths - 8" & 12". We switch twice a day with very few problems but, we don't have

We will be using the same paste for all boards. We would need to change head because of board widths. Is the amount of time changing heads comparable to the time changing squeegee blades?

If you visit the Cookson web site you will find a detailed list of trials of pastes and how they performed within the pump.
