8. Tighten the three screws whilst the motor is under tension.

9. On completion re-fit the printhead mechanism to the print carriage refit the

drive belt cover plate and re-connect all leads to the print carriage, left

hand side.

10. Refit the squeegees.

Fitting the

Squeegees

It is usual to fit two trailing edge squeegees and use the machine in the Print/

Print mode.

When fitting a single squeegee (trailing edge or diamond section) to the

machine, it must be fitted to the front squeegee mount only.

The following procedure describes a double trailing edge squeegee

configuration fit to the machine printhead mounting assembly.

1. From the Ready page, select Product Changeover.

2. Select Change Squeegees.

3. The print carriage is driven to the front position.

4. Open the front printhead cover.

5. Fit the rear squeegee to the rear squeegee mount tightening the thumb-

screws finger tight.

NOTE

The locking thumbscrews on the rear squeegee are positioned wider apart

than those fitted to the front squeegee and the keyway slot is positioned on the

left hand side of the rear squeegee.
