(5) Air removing mechanism
Another position of the purge cam shifts the slide cams, producing vertical motion of the air vent
rods. Pushing up the air vent rods opens the shut-off valves inside the air vent unit of the
head/carriage unit. Simultaneously adding negative pressure from the tube pump removes air
trapped in the damper assemblies.
