NOTE:
When storing the head/carriage unit for a long period, be sure to put an air buffer cap
on the head/carriage unit and store the unit in the head casing, as shown below. Leaving the
head/carriage unit out of the casing will cause the print nozzles and ink supply ports to dry up,
resulting in a damaged head.
