Support bars, so essentially the board is sitting ontop of beams that make a table. Fully supported with no soft spots

It could be the nozzles themselves causing the contamination. The coating could be worn off and oxidizing. Or it could be residue on the board or components that wasn't washed off.

Your post leads me to believe you always solder and flux each component individually, not in series. I have had great success fluxing the entire board, and then soldering. Maybe the cycle time would not allow for this method but that is almost always

Hi Dima, I use Speedprint printers mainly, and sometimes for some boards I encounter the same problem. Do you use pads or fiducials for alignment? Regards, Tamas

Every year, an engineer from the local service center comes to us and performs the necessary maintenance and calibration.

We had sucessful removed the solder mask by laser machine and got good result and quality without damage the copper layer. You may refer to youtube here by https://youtu.be/cQHaE3_fiqw

Based on these pictures, please check Board/Stencil co-planarity. Sometimes there might be a distance/gap between them helping this phenomenon(solder mask might be too thick). Also decreasing print speed, might help to mitigate it. You might be too f

Also check the ribbon cord connecting to the motherboard it's a PCI board.

I agree, and also, assuming you have SPI (if the solder paste roll is measured by laser) the SPI should not fail a board for such amount of missing paste.
