[ 3 ] Mechanisms constituting the head maintenance mechanism

(1) Head capping mechanism
When the power is off or the machine is not printing, this mechanism fits the head cap unit (which
contains two head caps) tightly over the print head to prevent the head nozzles from drying up and
to keep dust off the head nozzle surface.
This mechanism is driven by the head/carriage unit. When the head/carriage unit returns to its home
position, it presses against the head cap holder in the maintenance unit. The lift arms in the
maintenance unit raise the head cap unit, fitting it tightly over the head nozzle surface to protect it.
