Outline of Operation
While the power is off or the printer is standby, the BJ head ejection
face is covered by a Restoration tub to prevent clogging and sticking
dust (capping position).

After printing operation completes, the head is returned to the
capping position by the opposite operation to the above.
The head holder unit is driven by the head motor (M3), and the
capping position and the printing position are controlled by the
number of pulses driving the motor signal from the reference
position detected by the head home position sensor.
The restoration tub unit is driven by the cap motor (M4), and the
capping position and the evacuated position are controlled by the
cap home position sensor 1 and the cap position sensor 2.
