3.1 OVERVIEW
This section describes procedures for disassembling the main components of EPSON Stylus Color 600. 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 Color 600.
WARNING
Disconnect the power cable before disassembling or assembling the printer. Wear protective goggles to protect your 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 selon les lois et les règles de sécurité en vigueur.
CAUTION
Rev. A
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 Color 600 has no lower housing as previous EPSON printers, the printer mechanism can be taken out by only removing the upper housing. 1. 2. Open the printer cover and set the PG adjust lever on the right-hand side to (+) position. 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 reinstalling it. (Especially 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: C200 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. 2. 3. 4. 5. Remove the upper housing (Refer to section 3.2.1) Remove 5 screws (No.1 / three at the back of the printer mechanism and one each at both sides of the printer mechanism) 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". Fully separate "SHIELD PLATE, M/B" from the printer mechanism and remove all cables connected to the connectors on the main board; C200 MAIN. If you need further to remove each electric circuit board from "SHIELD PLATE, M/B", remove the screws fixing each board and remove it.
C200 MAIN BOARD: C206 PSB/PSE BOARD:
10 screws (No.1 = 7 screws, No.6 = 3 screws) 4 screws (No.1)
Also disconnect the cable from the connector; CN10 (locking type) on the C200 MAIN, when you remove the C206 PSB/PSE BOARD.
WORK POINT
Unlock the connector CN6/7 on the C200 MAIN by pulling its lock before disconnect the cables, and be sure to lock it when reconnecting the cables.

3.2.5 Disassembling the Printer Mechanism
This section describes the procedures for removing the main components consisting the printer mechanism.
3.2.5.1 Printhead Removal
1. Removing the upper housing. (Refer to section 3.2.1) 2. Rotate "Gear, 67.2" (largest gear at the left-hand side of the printer mechanism) toward the front to disengage the carriage lock mechanism, and move the carriage assembly to the middle of the printer. 3. Remove both black and color ink cartridges. 4. Remove both carriage cover assemblies from the carriage. 5. Remove "Twist Spring, 49" at left-hand side of the carriage and remove 1 screw (No.3) fixing "FASTNER, HEAD". Then, remove "FASTNER, HEAD" from the carriage. 6. Unhook the flat cables from the carriage assembly and tae out the printhead unit from the carriage. 7. Disconnect the cables from the connector of the printhead unit.
WORK POINT
Notice that the grounding plate is installed in correct position. (there are two fixing pins in the carriage) Be sure that fixing pin of the carriage is correctly located into the cut out of the printhead unit.
CAUTION
Once the ink cartridge is removed, it is not re-usable and always install brand-new ink cartridge before returning the printer to the user. When returning the printer to the user, be sure that the ink cartridge is installed and the carriage is at the capping position. (Turn the printer off while the carriage is at the capping position and pack it)
This part should be touching the CR axis receiver. Make sure that this protrusion is in the U ditch of the priht head side.
Make sure that protrusion of carriage is in the hole of the earth board.

3.2.5.2 Pump Assembly and Cap Assembly Removal
Removing the upper housing. (Refer to Section 3.2.1) Removing the control panel assembly. (Refer to section 3.2.3) Removing "Waste Ink Pad Assembly". (Refer to section 3.2.4) Loosen 2 screws (No.1) fixing the exit frame assembly and disengage the frame from the side frames. Then, put the printer mechanism on its back as you see the bottom of the mechanism. 5. At the right-hand of the mechanism, unhook the cap assembly by releasing one hook and take out the cap assembly by lifting up the right end of it. (Note that the cap assembly is still connected to the pump assembly by the ink tube.) 6. Remove 2 screws (No.5) fixing the pump assembly to the frame. 7. Unhook the pump assembly by releasing one hook and slide the pump assembly to the right direction to remove it. 1. 2. 3. 4.
CAUTION
Be careful not to damage rubber part of the cap assembly. (Damaging the rubber part causes incomplete capping and the nozzle condition become unstable.) Be careful with the followings when you handle "CLEANER, HEAD": Do not handle it with bare hands and avoid attaching any oil or dust. Make sure that the rubber side of "CLEANER, HEAD" is facing to the right.
WORK POINT
Be careful not to popping the components from the pump assembly when you remove it from the mechanism, as there is a spring inside the pump assembly. Be sure that the ink tube from the cap assembly is routed to the correct position and not pinched by the cap assembly ad the frame. Verify that "CLEANER, HEAD" moves smoothly by rotating "GEAR, 67.2" after you re-assemble the pump assembly. (Hold the cap assembly to the right while you rotating the gear for check)
