Pulling the CR Linear Scale from the right side of the Carriage

Unit may damage the Extension Spring 1.494. Therefore, always

remove the Spring 1.494 first, then remove the right end of the CR

Linear Scale, and pull the CR Linear Scale from the left side of the

Carriage Unit.

Refer to Figure 4-72, "Removing the CR Linear Scale".

When reinstalling the CR Linear Scale, do not twist the leg of the

Extension Spring 1.494.

Refer to Figure 4-72, "Removing the CR Linear Scale".

Reinstall the CR Linear Scale with the cut portion of its left end

facing upward as viewed from the printer front. (To install its

front and rear sides precisely)

Refer to Figure 4-72, "Removing the CR Linear Scale".

When reinstalling the Carriage Unit, connect the FFC to the

Encoder Sensor Board in advance, then fit the Carriage Guide

Shaft A to the Carriage Unit and fix the Carriage Unit to the

Printer Mechanism. If you attempt to fit the FFC after reinstalling

the Carriage Unit and Carriage Guide Shaft A as in the reversal of

the disassembly procedure, the FFC cannot be connected correctly

or may be damaged.

Refer to Figure 4-73, "Removing the FFC".

Before connecting the FFC to the CR Encoder Sensor Board, hitch

it on the hook of the Carriage Unit.

Refer to Figure 4-73, "Removing the FFC".

When reinstalling the Driven Pulley Stopper Holder, provide a

clearance by inserting a 0.3mm thickness gauge between the

Driven Pulley Holder and Driven Pulley Stopper Holder.
