2. Disconnect the following connectors from the print carriage, left hand side:

• Rear Squeegee Motor

• Front Squeegee Motor

• Home Sensors

• Squeegee Pressure Amplifier

3. Remove the printhead mechanism by unscrewing the four screws secur-

ing the unit to the print carriage.

4. Placing the unit on a secure surface, slacken off the three screws securing

the left hand motor to the support plate.

5. Fit the new belt in position.

6. Using a cable tie wrap or similar, provide a loop around the top of the body

of the motor enabling the motor to be pulled using a force meter. Ensure

that the force meter is pulled in the direction which the drive belt is fitted,

Rear Squeegee Motor Tensioning figure example refers.

7. Pull the force meter until a tension of 3 to 4kgs is monitored on the meter.

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.

6. Fit the front squeegee to the front squeegee mount ensuring the thumb-

screws are tightened finger tight.

NOTE

The locking thumbscrews on the front squeegee are positioned closer together

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

right hand side of the front squeegee.

7. Close the front printhead cover.

8. Press the System button.

9. Select Continue.

10. Select Back.

11. Carry out Squeegee Reference Height calibration, Calibrations section of

Mounts to Lateral

Squeegee Mounts

NOTE

The lateral squeegee - squeegee mechanism, is identical to a standard

squeegee mechanism. Refer to the sections: Fitting The Squeegee Printhead

Mechanism and Squeegee Drive Belt Replacement procedures.

To change from a printer with standard squeegee mounts fitted to having

lateral squeegee mounts fitted proceed as follows:

1. Power up the printer to allow it to initialise. The squeegees move to their

home positions.

2. Power down the printer.

3. Open the printhead front cover.

4. If fitted, remove and stow the standard squeegee blades safely away.

5. At the bottom of the squeegee mounts locate the three M4 cap headed

screws.

6. Using a 3mm Allen key, remove both squeegee mounts and stow them,

with their screws, safely away.
