Purge mode
In the purge mode, the motor rotational torque is transmitted to the purge gear, purge bevel gear,
and planetary arm to drive the pump switching unit or tube pump (depending upon the motor
rotational direction).

When the head/carriage unit moves left from the purge position, the tab on the carriage rear panel
releases the mode switching lever, allowing the switching lever spring to force the mode switching
lever and the clutch gear to the left (see the illustration on the previous page). The switching lever
spring is stronger, so forces the clutch gear spring back, disengaging it from the purge gear.
