Disassembly and Assembly

3.2.4 Disassembling the Printer Mechanism

Since the EPSON Stylus COLOR 400 does not have a lower housing, the printer mechanism is already

removed. Therefore, this section explains procedures for disassembling major parts or units of printer

mechanism.

1. Remove the housing. (See Section 3.2.1)

2. Rotate the flat gear (67.2 mm) toward yourself (front of printer), and release the carriage lock

mechanism. Then move the carriage to the left edge.

3. Take both black and color ink cartridges out of the printhead unit.

4. Remove the blue covers for black and color ink cartridges from the carriage assembly.

5. Remove the torsion spring (49 g) and 1 screw (No. 3), and take the head fastener out.

6. Remove the FFC being placed on the carriage assembly, and take the printhead unit out of the carriage.

7. Disconnect the FFC from the connector on the driver board built into the printhead unit.

;

Make sure the earth board is installed in the carriage correctly. (There are 2 location pins.)

;

When you put the printhead into the carriage, make sure the location pin on the carriage side is

placed in the notch in the printhead.

;

Since damage may occur once the ink cartridge is taken out, it cannot be used again. Be sure to

install a new ink cartridge when you return the printer to the user.

;

Pack the printer for transport with the new ink cartridge installed and the carriage in home position.

1. When you replace the printhead unit, perform the following adjustments. (See Chapter 4 for details):

1. Initial ink charge (See Chapter 4, Section 4.2.2.2.)

2. Write VH voltage ID (See Chapter 4, Section 4.2.2.3.)

3. Head angle adjustment (See Chapter 4, Section 4.2.2.4.)
