3.1 OVERVIEW

This section describes procedures for disassembling the main components of EPSON Stylus Photo. Unless otherwise specified, disassembly units or components can be reassembled by reversing the disassembly procedure. Therefore, no assembly procedures are included in this section. Precautions for any disassembly or assembly procedure are described under the heading “WORK POINT”. Any adjustments required after disassembling the units are described under the heading “REQUIRED ADJUSTMENT”.

3.1.1 Precautions for Disassembling the Printer

See the precautions below when disassembling or assembling EPSON Stylus Photo.

WARNING



Disconnect the power cable before disassembling or assembling the printer.



Wear protective goggles to protect y our eyes from ink. If ink gets in your eye, flush the eye with fresh water and see a doctor immediately.



If ink comes into contact with your skin, wash it off with soap and water. If irritation occurs, contact a physician.



A lithium battery is installed on the main board of this printer. Be sure to observe the following instructions when servicing the battery:



Keep the battery away from any metal or other batteries so that electrodes of the opposite polarity do not come in contact with each other.



Do not heat the battery or put it near fire.



Do not solder on any part of the battery. (Doing so may result in leakage of electrolyte from the battery, burning or explosion. The leakage may affect other devices close to the battery.)



Do not charge the battery. (An explosive may be generated inside the battery, and cause burning or explosion.)



Do not dismantle the battery. (The gas inside the battery may hurt your throat. Leakage, burning or explosion may also be resulted.)



Do not install the battery in the wrong direction. (This may cause burning or explosion.)

CAUTION

Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacture. Dispose the used batteries according to government’s law and regulations.



Risque d’explosion si la pile est remplacée incorrectment. Ne remplacer que par une pile du même type ou d’un type équivalent recommandé par le fabricant. Eliminer les piles déchargées s elon les lois et les règles de sécurité en vigueur.

CAUTION



Never remove the ink cartridge from the carriage unless manual specify to do so.



When transporting the printer after installing the ink cartridge, be sure to pack the printer for transportation without removing the ink cartridge.



Use only recommended tools for disassembling, assembling or adjusting the printer.



Apply lubricants and adhesives as specified. (See Chapter 6 for details.)



Make the specified adjustments when you disassemble the printer. (See Chapter 4 for details.)

3.2.1 Housing Removal

Since the EPSON Stylus Photo has no lower housing as previous EPSON printers, the printer mechanism can be taken out by only removing the upper housing.

1. Open the printer cover and set the PG adjust lever on the right-hand side to (+) position.

2. Remove 4 screws (No.2) and remove the upper housing.

WORK POINT

Pull the front end of the upper housing while lifting up the upper housing to remove it.

CAUTION

Be careful not to pinch the cables with the posts of the upper housing when reins talling it. (Espec ially with the cables from the motors and doing so causes fatal damage to the mechanism and the electric circuitry.)

3.2.2 Circuit Boards Removal

The electric circuit boards of the printer (Main control circuit board: C209 MAIN / Power supply circuit board: C206 PSB/PSE) are both installed on single metal chassis and attached to the printer mechanism. Therefore, first detach the metal chassis from the printer mechanism to remove the electric circuit boards.

1. Remove the upper housing (Refer to section 3.2.1)

2. Remove 5 screws (No.1 / three at the back of the printer mechanism and one each at both sides of the printer mechanism)

3. Slightly pull out “SHIELD PLATE, M/B” (metal chassis) from the printer mechanism and take out the cable holders inserted to the edge of “SHIELD PLATE, M/B”.

4. Fully separate “SHIELD PLATE, M/B” from the printer mechanism and remove all cables connected to the connectors on the main board; C209 MAIN.

5. If you need further to remove each electric circuit board from “SHIELD PLATE, M/B”, remove the screws fixing each board and remove the board.



C209 MAIN BOARD: 10 screws (No.1 = 7 screws, No.6 = 3 screws)



C206 PSB/PSE BOARD: 4 screws (No.1)

Also disconnect the cable from the connector; CN10 (locking type) on the C209 MAIN, when you remove the C206 PSB/PSE BOARD.

WORK POINT

Unlock the connector CN6/7 on the C209 MAIN by pulling its loc k before disconnect the cables, and be sure to lock it when reconnecting the cables.

REQUIRED ADJUSTMENT

Be sure to perform the following adjustments when the C209 MAIN board is replaced:

1) VH Setting (Refer to Chapter 4 / Section 4.2.2.4.)

2) Head Angular Adjustment (Refer to Chapter 4 / Section 4.2.2.5.)

3) Bi-D Alignment Adjustment (Refer to Chapter 4 / Section 4.2.2.6.)

3.2.3 Control Panel Removal

1. Remove the upper housing (Refer to Section 3.2.1)

2. Remove 2 screws (No.1) and remove the “PANEL, ASSEMBLY” and “HOUSING, PANEL, LEFT” from

the printer mechanism and disconnect the flat cable from the connector of the panel assembly.

WORK POINT

By removing the control panel assembly, the stacker assembly is also detached from the printer mechanism since it is held by the control panel assembly.
