the envelope selector. When the air level sensors
detect that there is air in a tank, the system activates
the air release solenoid to suck air from the tank. The
partial vacuum pulls in the sides of the tank. This
changes the position of the feeler on the side of the
tank (used for ink level detection) and pulls ink into the
tank from the ink supply tube.
