(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.
Note: If the main drain tube and air vent tube are disconnected from the ink absorber box,
they are reusable only one time by trimming their ends vertically 10 mm with scissors clear
and free of oil. Check that their cut surfaces are free of oil. If it is the second time for those
tubes to be disconnected, they need to be replaced.
(4) Remove the four screws (three "a" screws and one "b" screw) and detach the maintenance
unit from the engine unit.
