7.2.4 Y Drive Belt Damage

 Outline

The driven pulley tilt over the acceptable range caused by assembly error may slip the Y belt onto the flange and

damage the belt. When this problem occurred, replace the belt and adjust the pulley tilt with shim.

We also recommend you to check this at the regular maintenance.

 Tools

 Phillips screwdriver

 Shim: Y-T Spacer L0.4 (M511789)

 Procedure

1. Remove the covers in the following order.

1. ICU Cover 30

2. Maintenance Cover L30

3. Left Cover 30

4. C Y-T Cover

2. Move the head in full width from the right (left) to the left

(right) manually. Check the Y-belt condition on the Y-T pulley.

When the Y-belt has gap on both sides, or when the belt moves

up and down in conjunction with the head, adjustment with the

shim is not required.

Be sure to turn OFF the MAIN power to prevent an unexpected movement of the printer while perform-

ing these procedures.

Cautions for adding the shim

 Make sure to add only one piece of the shim. Adding more than two pieces may deform the Y-T pulley

BKT ASSY.

 Additional adjustment is not required because the shim is made to fulfill a proper alignment with one.

The alignment cannot be measured on site. Follow the instructions below.
