The procedures for changing the ink combination from 4C+W model to 4C model are as follows:

4C Model

IE: Ink End Detection

When installing, make sure to insert tubes and stoppers correctly.

When routing tubes, be careful not to bend the tubes or make scratches on the tubes.

  1. Remove the rear left cover. (Removing the Rear Left Cover)
  2. Remove the left upper cover [A]. (Changing the Joints of Branch Section and Connecting Circulation Tubes)
  3. Attach the sealing materials (MTLLP-2) [B] to the joint [A] of the tube extending from the ink end detection [IE2].
  4. Connect the joint [E] branching from the T-shaped joint [D] and the joint [C] of the tube extending from the solenoid valve [V2].
    The picture below shows the solenoid valve V1/V2.

    Connect tubes of the other solenoid valves (V3/V4, V5/V6, and V7/V8) in the same procedure.

  5. Attach the sealing materials (FTLLP-1) [B] to the joint [A] of the tube extending from the ink end detection [IE2].
  6. Connect the joint [D] branching from the T-shaped joint [C] and the joint of the filter upper side [E].

    Connect tubes of the other ink end detections (IE3/IE4, IE5/IE6, and IE7/IE8) in the same procedure.

  7. Loosen all the screws retaining the joint branch unit [A] by rotating about from one to one and half times with a driver.
  8. Connect the eight tubes for solenoid valve [A], the eight tubes for joint section [B], and the 12 stoppers for joint section [C] as shown below.

    • The eight tubes for solenoid valve [A]
    • The eight tubes for joint section [B]
    • The 12 stoppers for joint section [C]
  9. Tighten all the loosen screws in step 7.
  10. Fix the tubes.

    Be careful not to bend the tubes.

  11. Attach the left upper cover.
  12. Attach the rear left cover.
