(2) Release the left end of the switching lever guide from the maintenance unit (viewed from the
rear) and remove the guide.
(3) If the ink absorber box has not been removed, pull out the main drain tube and air vent tube
from the ink absorber box.
Note Pinch the end of each tube with a clip in order to prevent drained ink from leaking and the
•
machine from getting stained with leaked ink.
When the main drain tube has been removed from the ink absorber box, you can cut the
•
tube tip and reuse the tube once. Use clean scissors to cut the tube 10 mm vertically. Make
sure that the cut surface of the tube is free of oil. If it is the second time that the tube is
pulled, you will need to replace it with a new one.
(4) Remove the four screws (three "a" screws and one "b" screw) to separate the maintenance unit
from the engine unit.
