Back end components and their main roles
- Damper assemblies
Each assembly has two roles: dampening the ink pressure fluctuations* in the ink supply tube as
the carriage moves and collecting air bubbles that grow in the ink flow path.
*
Ink pressure fluctuations: As the head/carriage unit travels, inertia means that the ink remains in the
same place, temporarily raising or lowering the pressure in the right chamber.
- Air vent unit
At regular scheduled intervals, this vents any air bubbles that have accumulated in the damper
assemblies. The air vent rods in the maintenance unit push up the shut-off valves, opening the air
vent flow paths.
