(a)Installing carriage drive wires

When replacing the carriage drive wires with new wires, proceed as illustrated below:

				Motor pulley
	Carriage 2 pulley		Carriage drive wire	2GT-Z26 (26 tooth)

Idler pulley			Wire take-up pulley/motor speed reduction pulley
			φ 27.37/2GT-Z43
φ 20

(b)Adjusting the carriage drive wires

Since the wires are applied with proper tension by tension springs, there is no need for tension adjustment.

Note:

Check that the wire tension is identical for both front and rear wires and is properly applied.

(c) Adjusting the positions of carriages 1 and 2

1.Loosen 2 screws (one each on the front and rear) which are fixing carriage 1 to the wires, and another 1 screw (on the front) which are fixing carriage 2 to the wires.

2.Move carriage 2 to the exit side. Insert the car- riage jigs into the jig-insertion holes, one each on the front and rear sides of carriage 2, and fasten the screw on the front side of carriage 2.

3.While placing the protruding parts of carriage 1 against the carriage jigs, fasten carriage 1 to the wire on both front and rear sides.

4.Pull out the carriage jigs.
