Here's what we hear you saying: * Trying to repair a printed circuit board assembly * There's a problem replacing a 57 pin, 20 thou connector * Can't get enough solder paste on the connector leads * Printing paste, replacing the connector, then reflowing the assembly

If so, try either: * Open up the apertures of your stencil ... OR * Use a thicker stencil ... OR * In addition to what you're presently doing, use a manual paste dispense gun to lay a line of paste over the connector leads. Then reflow

If not, give us more detail
