4.  Loosen 2 screws (No.1) fixing the exit frame assembly and disengage the frame from the side
 frames. Then, put the printer mechanism on its back as you see the bottom of the mechanism.
5.  At the right-hand of the mechanism, unhook the cap assembly by releasing one hook and take out
 the cap assembly by lifting up the right end of it. (Note that the cap assembly is still connected to
 the pump assembly by the ink tube.)
6.  Remove 2 screws (No.5) fixing the pump assembly to the frame.
7.  Unhook the pump assembly by releasing one hook and slide the pump assembly to the right
 direction to remove it.
Be careful not to damage rubber part of the cap assembly. (Damaging the rubber part causes
   incomplete capping and the nozzle condition become unstable.)
Be careful with the followings when you handle “CLEANER, HEAD”:
•E
Do not handle it with bare hands and avoid attaching any oil or dust.
•E
Make sure that the rubber side of “CLEANER, HEAD” is facing to the right.
Be careful not to popping the components from the pump assembly when you remove it from the
   mechanism, as there is a spring inside the pump assembly.
Be sure that the ink tube from the cap assembly is routed to the correct position and not pinched
   by the cap assembly ad the frame.
Verify that “CLEANER, HEAD” moves smoothly by rotating “GEAR, 67.2” after you re-assemble
   the pump assembly. (Hold the cap assembly to the right while you rotating the gear for check)
