3.3.2 Structure of purge unit
1) Purge drive gear
The purge drive gear is driven via the transmission arm gear by the feed roller,
which is, in turn, driven by the paper feed motor. The purge drive gear operates the
cam that controls the pump operation and wiping. The cam position is sensed by
the purge sensor.
The purge drive gear switches between purging and wiping depending on its
direction of rotation.
