1.2.1 Ink passages
Be careful not to touch the ink passages of the printer or to allow ink to stain the
workbench, hands, clothes or the printer under repair.
The ink flows through the ink bottle unit, sub-tank unit, carriage unit, purge unit,
nozzle check unit, waste ink tank unit and the ink tubes that relay ink to each unit.
Among these passages, the ink bottle unit and waste ink tank unit have sensors to
detect leakage of ink at the bottom of the unit.
