Purge mechanism
The paper feed motor drives the purge mechanism.
The counterclockwise rotation of the paper feed motor drives the purge cam that aligns the
pump switching unit with either the black or color ink drain position.
Next, the paper feed motor reverses to activate the tube pump, producing negative pressure to
drain the air and old ink from the head nozzles and channels into the ink absorber box.
