electronic microswitch sends a signal to the marker's electronic board telling it to begin the firing sequence. The board then actuates the solenoid which is provided with air from the LPR. When the solenoid valve is actuated, air that normally holds the hammer in the full-back position is re-routed through the ram assembly and now drives the hammer forward at a rapid rate. The hammer then pins open the valve for a period of 6-16ms (this time is called the dwell). Since the marker's bolt is linked to the hammer, it travels forward at the same time carrying a paintball forward, passed the detents, into the firing position. Air travelling upwards through the, now open, valve is routed through the bolt and the paintball is shot out the barrel through a combination of air pressure and kinetic energy imparted from the bolt movement. Once the dwell time has passed, the solenoid returns the hammer (and thus the bolt) to the full-back position by routing the LPR-sourced air back through the default passage.
