Caution regarding Assembling Disassembling of the Printer Mechanism and How to Ensure of Quality on Reassembled Product

On current low end models, we 've basically forbidden 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.

For this reason, 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 Waste Ink Pad with a new one.

Therefore, we clarify caution regarding assembling/disassembling of the printer mechanism without Housing, Lower, and how to ensure of quality on repaired products in this section.

[Caution regarding assembling/disassembling of the printer mechanism] 1) Main frame

(a) Control of assembled standard position. [Reason]

The assembled 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.

[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 tabs.

(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 failure/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 failure/operation failure occurs.

[Service treatment]

Hold the opposite side with hand while you are installing the above parts.

- 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.

2) Front frame

(a) Control of vertical level [Reason]

There is a possibility that printing failure 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 occurs in user's further 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.
