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