1.1 Overview
This section describes procedures for disassembling the main components of the Stylus C63/64/83/84. Unless otherwise specified, disassembly units or components can be reassembled by reversing the disassembly procedure. Things, if not strictly observed, that could result in injury or loss of life are described under the heading “Warning”. Precautions for any disassembly or assembly procedures are described under the heading “CAUTION”. Chips for disassembling procedures are described under the heading “CHECK POINT”.
If the assembling procedure is different from the reversed procedure of the disassembling, the procedure is described under the heading “REASSEMBLY”.
Any adjustments required after reassembling the units are described under the heading “ADJUSTMENT REQUIRED”. When you have to remove any units or parts that are not described in this chapter, refer to the exploded diagrams in the appendix.
Read precautions described in the next section before starting.
1.1.1 Precautions
See the precautions given under the handling “WARNING” and “CAUTION” in the following column when disassembling or assembling EPSON Stylus PC63/64/83/84..
WARNING Disconnect the power cable before disassembling or assembling the printer.
If you need to work on the printer with power applied, strictly follow the instructions in this manual.
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.
Always wear gloves for disassembly and reassembly to avoid iujury from sharp metal edges.
To protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components.
Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off with soap and water immediately. If irritation occurs, contact a physician.
WARNING Avant de commencer, assure vous que l’imprimante soit eteinte et que le cordon d’alimentation soit debranche.
Veillez a jeter les piles usagees selon le reglement local.
CAUTION 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.
When transporting the printer after installing the ink cartridge,
CAUTION be sure to pack the printer for transportation without removing the ink cartridge.
Use only recommended tools for disassembling, assembling or adjusting the printer.
Observe the specified torque when tightening screws.
Apply lubricants and adhesives as specified. (See Chapter 3 for details.)
Make the specified adjustments when you disassemble the printer.
(See Chapter 5 for details.)
Make sure the tip of the waste ink tube is located at correct position when reassembling the waste ink tube. Otherwise it will cause ink leakage.

1.2Caution regarding assembling/disassembling of the printer mechanism, and how to ensure of quality on re-assembled product
On current low end models, we basically forbided to remove Housing (Lower) from Printer mechanism in your repair. This is because there is a possibility of main frame deformation when a part (such as Ink system) is removed from Printer mechanism without Housing (Lower).
Therefore, if you want to replace Ink system/PF motor, we recommend to replace with new Printer mechanism with Housing (Lower).
On these models, you have to remove Housing (Lower) from printer mechanism when replacing [Porous Pad] with new one.
Therefore, we clarify caution regarding assembling/disassembling of the printer mechanism without Housing (Lower), and how to ensure of quality on repaired productsin this section.
[Caution regarding assembling/disassembling of the printer mechanism]
1)Main frame
(a)Control of assembled standard position. [Reason]
The assembed accuracy of each part composed of Printer mechanism is based on Housing (Lower).
[Service treatment]
Confirm that there is no gap between main frame and Housing (Lower). [Reference]
To ensure the assembled accuracy, you have to control the assembled standard position of main frame against X/Y/Z-axis direction. [X-axis direction]
-Make sure that main frame is correctly placed on the groove of Housing (Lower).
-Make sure that there is no gap between main frame and Housing (Lower). [Y-axis direction]
Make sure that cut-out portion of main frame is correctly placed on the square protrusion of Housing (Lower).
[Z-axis direction]
-Make sure that there is no gap between main frame and Housing (Lower).
-Make sure that the left side of Printer mechanism is correctly fixed by two hooks.
(b)Control of vertical level of guide rail (Guide rail means the portion latched by hooks of IC holder & Print head assy..)
[Reason]
There is a possibility that printing failre/operation failure occurs by guide rail deformation.
[Service treatment]
-Do not remove [Mounting Plate, M/B] from Printer mechanism.
-Hold up the specified position of main frame to avoid the deformation.
(c)How to assemble of ASF unit/Circuit board/Paper guide upper
[Reason]
There is a possibility that main frame deformation is caused extra force in assembling. As the result, printing failre/operation failure occurs.
[Service treatment]
Hold the opposite side by by hand while you are installing the above parts.
2)Front frame
(a)Control of vertical level [Reason]
There is a possibility that printing failre occurs by front frame deformation. [Service treatment]
Handle Front frame in assembling/disassembling carefully.
3)IC holder
(a)Handling of IC holder
[Reason]
If IC holder is damaged in assembling/disassembling of your repair, there is a possibility that vital problem occus in user’s futher operation.
[Service treatment]
Released two hooks of IC holder from the inside of IC holder by the tweezer.
[How to ensure of quality on re-assembled product]
We judge that the quality of re-assembled product is ensured if there is no problem about the print result by adjustment program..
