Komori Spica 429P Form Rollers Stay on plate

When I finish printing, the water rollers disengage from the plate but the ink forms remain on the plate, I have to raise the rollers with a tool near the adjustment screws, as if the air pressure remains partly in the cylinders. Does anyone have any idea what the problem is?

 

Is it happening on all units or just one? Which year is the machine?

 

Air Pressure Problem! It's Ok now, compressor not enough pressure.
