Air removing mechanism
Other two positions of the purge cam shift two slide cams--one for black ink, the other for color
inks, producing vertical motion of a single air vent rod for black ink and three air vent rods for
color ink, respectively.
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.
