2.2Caution regarding assembling/disassembling the printer mechanism, and how to ensure the quality of reassembled product

For the existing Low End models, it is basically forbidden to remove "Housing, Lower" from "Printer Mechanism". This is because the strength of "Frame, Main" is not strong enough, therefore, "Frame, Main" may be transformed when removing/ reinstalling it from/to "Housing, Lower".

For that reason, when replacing "Ink System" or "PF Motor", it is recommended to replace not only "Housing, Lower" but also "Printer Mechanism".

For this printer, it is necessary that "Housing, Lower" be removed from "Printer Mechanism" when replacing "Waste ink Pads" or "Ink System".

Therefore, this chapter specifies the disassembly/assembly of "Printer Mechanism" which "Housing, Lower" has been taken out in order to secure the quality of the repaired items.

†Caution for disassembly/assembly of Printer Mechanism

1."Printer Mechanism" with "Housing, Lower"

•Do not hold "Guide Plate, CR" ⇒ Transforming of "Frame, Main" and "Guide Plate, CR" may give some bad influence to PG or printing.

•Do not touch "CR Guide Shaft" and/or the surface of the head nozzle.

2."Printer Mechanism" without "Housing, Lower"

•Manage the standard values for installation. (See below)

•First, remove "Support Plate, Frame, Main". Then, remove "Roller PF Assy.", "Roller EJ Assy." and "Paper Guide, Front".

•Make sure to manage "Waste Ink Tube".

•Be careful with the interconnection of "Star Wheel/CDR Sensor" connector cable.

•Assemble "Cam, CR, Left" while gearing with the APG gear.

„Management of the reference position for installation

[Reason]

Accurate installation for each component of "Printer Mechanism" is on a basis of "Housing, Lower".

[Support for Service]

Check if there is no gap between "Frame, Main" and "Housing, Lower".

[Reference]

In order to ensure the accuracy for installation, it is necessary to manage the reference position for installation in X, Y and Z direction.

[X-axis]

•Check if "Frame, Main" is correctly set to the groove of "Housing, Lower".

•Check if there is no gap between "Frame, Main" and "Housing, Lower".

[Y-axis]

•Check if the slot of "Frame, Main" is correctly attached to the projection of "Housing, Lower".

[Z-axis]

•Check if there is no gap between "Frame, Main" and "Housing, Lower".

•Check if correctly secured with the hooks (2 on the left, 1 on the right, 1 on the right front) of "Printer Mechanism".

„Management of the perpendicular accuracy of "Guide Plate, CR" (The standards of the guide rail's perpendicular direction is on the basis of the hooks of "Carriage Unit" and "Print Head".)

[Reason]

Deformation of "Guide Plate, CR" may cause the defective print/operation.

[Support for Service]

Specify the correct raising position for "Main Frame" so that it will not be deformed.
