3.2.4.3 Removing the Pump Assembly and Cap Assembly

1. Remove the housing. (See Section 3.2.1.)

2. Remove the control panel. (See Section 3.2.3.)

3. Remove waste ink drain pad tray assembly A. (See Section 3.2.4.2.)

4. Loosen 2 screws on the edges of the paper eject frame assembly, and float the paper eject assembly.

5. Raise the printer mechanism toward the ASF side, so you can see the bottom of the printer mechanism.

6. On the right side of the frame, remove the hook holding the cap assembly, and release 2 protrusions

attached to the frame. Lift up the right side of the cap assembly, and then take it out toward the bottom of

the printer mechanism. Remember that the cap assembly is still connected to the pump assembly by the

ink tube at this point. (See the figures on the next page.)

7. Remove 2 screws (No. 5) securing the pump assembly to the frame. (See the figures on the next page.)

8. Release the hook securing the pump assembly to the frame and remove the pump assembly, moving it

toward the right. (See the figures on the next page.)

;

Do not damage the rubber part (black square) of the cap installed in the cap assembly. (If this gets

damaged, it will not be able to adhere closely to the surface of the printhead and may cause a

malfunction in operation.)

;

When replacing the head cleaner built into the pump assembly, be careful of the following points:

• Do not touch the head cleaner with your bare hands. Use gloves or tweezers.

• Do not let oil or grease touch the head cleaner.

• When installing the head cleaner, insert the rubber side (darker black side) toward the right side of

the frame.

;

When installing the pump assembly, do not tighten the screw more than the necessary torque.

;

There is a spring among the gears in the pump assembly, so be careful that the parts do not pop out

during disassembly and assembly.

;

When assembling, be careful not to crush or stretch the ink tube connecting the pump assembly and

cap assembly.

;

After installing the pump assembly, make sure the cleaner parts can move forward and back by

rotating the gear (67.2 mm).
