Disassembly/Reassembly

Detailed Disassembly/Reassembly Procedure for each Part/Unit

Confidential

Ink Supply Unit

To prevent ink leakage, make sure not to separate the ink tubes from the I/C Holder Unit or the Ink Selector by removing the screws (x2). Loosening
the screws even just once will cause ink leakage, therefore, make sure to replace the Ink Supply Unit with a new one.



When removing the Ink Supply Unit, follow the procedure below.
1. Release the Head FFC from the hooks (x2 each) of the Ink Tube Holders (x2). Be careful not to damage the Head FFC then.
2. Remove the screws (x2) that secure the Ink Selector, and remove the Ink Selector from the CR Unit.
3. Disconnect the Decomp Tube from the I/C Holder Unit.

on the Main Board, and then release the FFCs from the Cable Holder Rear and Cable Holder Left.

5. Remove the screws (x3) that secure the I/C Holder Unit, and remove the I/C Holder Unit.



When removing the Ink Selector on the way to the target part, perform only Step 1 and 2 above. Be careful not to contaminate the surroundings
with ink from the Ink Selector when taking subsequent steps.



When removing the I/C Holder Unit on the way to the target part, perform only Step 3 to 5 above. Place the removed I/C Holder Unit on the 0-
