Caution Regarding Assembling/Disassembling Of The Printer Mechanism, And How To Ensure Of Quality On Re-Assembled Product - Epson C63, C64, C83, C84 Service Manual

EPSON Stylus C63/64/83/84
1.2 Caution 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.
Disassembly and Assembly

Caution regarding assembling/disassembling of the printer mechanism, and how to ensure of quality on re-assembled product

(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..
